Saizen (HGH, Human Growth Hormone) [Somatropin]

Saizen click.easy, is a recombinant human growth hormone (rHGH) for injection. It is a liquid consisting of the identical sequence of 191 amino acids of human growth hormone. The molecular formula is C990H1528N262O300S7. Its molecular weight is 22,125 Daltons.

As with no other doping drug, growth hormones are still surrounded by an aura of mystery. Some call it a wonder drug which causes gigantic strength and muscle gains in the shortest time. Others consider it completely useless in improving sports performance and argue that it only promotes the growth process in children with an early stunting of growth. Some are of the opinion that growth hormones in adults cause severe bone deformities in the form of overgrowth of the lowerjaw and extremities. And, generally speaking, which growth hormones should one take the human form, the synthetically manufactured version, recombined or genetically produced form and in which dosage? All this controversy about growth hormones is so complex that the reader must have some basic information in order to understand them.

The growth hormones is a polypeptide hormone consisting of 191 amino acids. In humans it is produced in the hypophysis and released if there are the right stimuli (e.g. training, sleep, stress, low blood sugar level). It is now important to understand that the freed HGH (human growth hormones) itself has no direct effect but only stimulates the liver to produce and release insulin-like growth factors and somatomedins. These growth factors are then the ones that cause various effects on the body. The problem, however, is that the liver is only capable of producing a limited amount of these substances so that the effect is limited. If growth hormones are injected they only stimulate the liver to produce and release these substances and thus, as already mentioned, have no direct effect.

The use of these STH (somatotropic hormone) compounds offers the athlete three performance-enhancing effects. STH has a strong anabolic effect and causes an increased protein synthesis which manifests itself in a muscular hypertrophy (enlargement of muscle cells) and in a muscular hyperplasia (increase of muscle cells.) The latter is very interesting since this increase cannot be obtained by the intake of steroids. This is probably also the reason why STH is called the strongest anabolic hormone. The second effect of STH is its pronounced influence on the burning of fat. It turns more body fat into energy leading to a drastic reduction in fat or allowing the athlete to increase his caloric intake. Third, and often overlooked, is the fact that STH strengthens the connective tissue, tendons, and cartilages which could be one of the main reasons for the significant increase in strength experienced by many athletes. Several bodybuilders and powerlifters report that through the simultaneous intake with steroids STH protects the athlete from injuries while inereasing his strength.

You will say that this sounds just wonderful. What is the problem, however since there are still some who argue that STH offers nothing to athletes? There are, by all means, several athletes who have tried STH and who were sadly disappointed by its results. However, as with many things in life, there is a logical explanation or perhaps even more than one:
1. The athlete simply has not taken a sufficient amount of STH regularly and over a long enough period of time. STH is a very expensive compound and an effective dosage is unaffordable by most people.

2. When using STH the body also needs more thyroid hormones, insulin, corticosteroids, gonadotropins, estrogens and what a surprise androgens and anabolics. This is also the reason why STH, when taken alone, is considerably less effective and can only reach its optimum effect by the additive intake of steroids, thyorid hormones, and insulin, in particular. But we must point out in this case that STH has a predominantly anabolic effect. There are three hormones which are needed at the same time in order to allow for maximum anabolic effect. These are STH, insulin, and an LT-3 thyroid hormone, such as, for example, Cytomel T3. Only then can the liver produce and release an optimal amount of somatomedin and insulin-like growth factors. This anabolic effect can be further enhanced by taking a substance with an anticatabolic effect. These substances are-everybody should probably know by now-anabolic/androgenic steroids or Clenbuterol. Then a synergetic effect takes place.`Are you still wondering why pro bodybuilders are so incredibly massive but, at the same time, totally ripped while you are not. Most athletes have tried STH during preparation for a competition in that phase when the diet is calorie-reduced.

The body usually reacts by reducing the release of insulin and of the L-T3 thyroid hormone. And, as was described under point 2, this is not an advantageous condition when STH is expected to work well. Well, we almost forgot. Those who combine Clenbuterol with STH, should know that Clenbuterol (like Ephedrine) reduces the body`s own release of insulin and L-T3. True, this seems a little complicated and when reading it for the first time it might be a little confusing; however it really is true: STH has a significant influence on several hormones in the human body; this does not allow for a simple administration schedule.

As said, :ST: is not cheap and those who intend to use it should know a little more about it. If you only want to burn fat with STH you will only have to remember user information for the part with the L-T3 thyroid hormone as is printed by Kabi Pharmacia GmbH for their compound Genotropin:

“The need of the thyroid hormone often inereases during treatment with growth hormones.”

3. Since most athletes vho want to use STH can only obtain it if prescribed by a physician, the only supply source remains the black market. And this is certainly another reason why some athletes might not have been very happy with the effect of the purchased compound. How could he, if cheap HCG was passed off as expensive STH?

Since both compounds are available as dry substances, all that would be needed is a new label of Serono`s Saizen or Lilly`s Humatrope on the HCG ampule. It is no longer fun when somebody is paying $200 for 5000 I.U. of HCG, only worth $ 12, and thinking that he just purchased 4 I.U. of STH. And if you think this happens only to novices and to the ignorant, ask Ben Johnson. “Big Ben,” who during three tests within five days showed an above-limit testosterone level, was not a victim of his own stupidity but more likely the victim of fraud. According to statistics by the German Drug Administration, 42% of the HGH vials confiscated on the North American black market are fakes. In addition to a display of labels in the Dutch or Russian language the fakes are distinguished from the original product, in sofar as the dry substance is not present as lyophilic but present as loose powder. The fakes confiscated so far use the name “Humatrope 16” under the name of Lilly Company (with Dutch denomination) or “Somatogen” (in Russian).” Nowhere can this much money be made except by faking STH. Who has ever held original growth hormones in his hand and known how they should look?

4. In a few very rare cases the body reacts by developing antibodies to the exogenous STH, thus making it ineffective. The question of the right dosage, as well as the type and duration of application, is very difficult to answer. Since there is no scientificresearch showing how STH should be taken for performance improvement, we can only rely on empirical data, that is experimental values. The respective manufacturers indicate that in cases of hypophysially stunted growth due to lacking or insuffieient release of growth hormones by the hypophysis, a weekly average dose of 0.3 I.U/ week per pound of body weight should be taken. An athlete weighting 200 pounds, therefore, would have to inject 60 I.U. weekly. The dosage would be divided into three intramuscular injections of 20 I.U. each. Subcutaneous injections (under the skin) are another form of intake which, however would have to be injected daily, usually 8 I.U. per day. Top athletes usually inject 4-16 I.U./day. Ordinarily, daily subcutaneous injections are preferred. Since STH has a half life time of less than one hour, it is not surprising that some athletes divide their dail dose into three or four subcutaneous injections of 2-4 I.U. each.

Application of regular small dosages seems to bring the most effective results. This also has its reasons: When STH is injected, serum concentration in the blood rises quickly, meaning that the effect is almost immediate. As we know, STH stimulates the liver to produce and release somatomedins and insulin like growth factors which in turn effect the desired results in the body. Since the liver can only produce a limited amount of these substances, we doubt that larger STH injections will induce the liver to produce instantaneously a larger quantity of somatomedins and insulin-like growth factors. It seems more likely that the liver will react more favorably to smaller dosages. If the STH solution is injected subcutaneously several consecutive times at the same point of injection, a loss of fat tissue is possible.

Therefore, the point of injection, or even better, the entire sisde of the body should be continuously, changed in order to avoid a loss of local fat tissue (lipoathrophy) in the injection cell. One thing has manifested itself over the years: The effect of STH is dosage-dependent. This means either invest a lot of money and do it right or do not even begin. Half-hearted attempts are condemned to failure Minimum effective dosages seem to start at 4 I.U. per day. For comparison: the hypophysis of a healthy; adult, releases 0.5-1.5 I.U. growth hormones daily.

The duration of intake usually depends on the athlete`s financial resources. Our experience is that STH is taken over a prolonged period, from at least six weeks to several months. It is interesting to note that the effect of STH does not stop after a few weeks; this usually allows for continued improvements at a steady dosage. Bodybuilders who have had positive results with STH have reported that the build-up strength and, in particular, the newly-gained muscle system were essentially maintained after discontinuance of the product. It remains to be clarified what happens with the insulin and LT-3 thyroid hormone.

Athletes who take STH in their build-up phase usually do not need exogenous insulin. It is recommended, in this case, that the athlete eats a complete meal every three hours, resulting in 6-7 meals day. This causes the body to continuously release insulin so that the blood sugar level does not fall too low. The use of LT-3 thyroid hormones, in this phase, is carried out reluctantly by athletes. In any case, you must have a physician check the thyroid hormone level during the intake of STH. Simultaneous use of anabolic /androgenic steroids and/or Clenbuterol is usually appropriate. During the preparation for a competition the use of thyroid hormones steadily inereases. Sometimes insulin is taken together with STH, as well as with steroids and Clenbuterol.

Apart from the high damage potential that exogenous insulin can have in non-diabetics, incorrect use will simply and plainly make you “FAT! Too much insulin activates certain enzymes which convert glucose into glycerol and finally into triglyceride. Too little insulin, especially during a diet, reduces the anabolic effect of STH. The solution to this dilemma? Visiting a qualified physician who advises the athlete during this undertaking and who, in the event of exogenous insulin supply, checks the blood sugar level and urine periodically.

According to what we have heard so far, athletes usually inject intermediately-effective insulin having a maximum duration of effect of 24 hours once a day. Human insulin such as Depot-H-Insulin Hoechst is generally used. Briefly-effective insulin with a maximum duration of effect of eight hours is rarely used by athletes. Again a human insulin such as H-Insulin Hoechst is preferred. The undesired effect of growth hormones, the so-called side effects, are also a very interesting and hotly-discussed issue. Above all it must be said: STH has none of the typical side effects of anabolic/androgenic steroids including reduced endogenous testosterone production, acne, hair loss, aggressiveness, elevated estrogen level, virilization symptoms in women, and increased water and salt retention.

The main side effects that are possible with STH are an abnormally small concentration of glucose in the blood (hypoglycemia) and an inadequate thyroid function. In some cases antibodies against growth hormones are developed but are clinically irrelevant. What about the horror stories about acromegaly, bone deformation, heart enlargement, organ conditions, gigantism, and early death? In order to answer this question a clear differentiation must be made between humans before and after puberty. The growth plates in a person continue to grow in length until puberty.

After puberty neither an endogenous hypersection of growth hormones nor an excessive exogenous supply of STH can cause additional growth in the length of the bones. Abnormal size (gigantism) initially goes hand in hand with remarkable body strength and muscular hardness in the afflicted; later, if left untreated, it ends in weakness and death. Again, this is only possible in pre-pubescent humans who also suffer from an inadequate gonadal function (hypogonadism). Humans who suffer from an endogenous hypersecrehon after puberty and whose normal growth is completed can also suffer from acromegaly. Bones become wider but not longer. There is a progressive growth in the hands and feet and enlargement of features due to the growth of the lower jaw and nose. What the authorities like to do now is to present extreme cases of athletes suffering from these malfunctions in order to discourage others and to drum into athletes the fact that with the exogenous supply of growth hormones they would suffer the same destiny. This, however, is very unlikely, as reality has proven.

Among the numerous athletes using STH comparatively few are seven feet tall Neanderthalers with a protruded lower jaw, deformed skull, claw like hands, thick lips, and prominent bone plates who walk around in size 25 shoes. In order to avoid any misunderstandings, we do not want to disguise the possible risks of exogenous STH use in adults and healthy humans, but one should at least try to be openminded. Acromegaly, diabpetes, thyroid insuficiency, heart muscle hypertrophy, high blood ressure, and enlargement of the kidneys are theoretically possible if STH is used excessively over prolonged periods of time; however, in reality and particularly when it comes to the external attributes, these are rarely present.

Some athletes report headaches, nausea, vomiting, and visual disturbances during the first weeks of intake. These symptoms disappear in most cases even with continued intake.

The most common problems with STH occur when the athlete intends to inject insulin in addition to STH. The substance somatropin is available as a dried powder and before injecting it must be mixed with the enclosed solution-containing ampule. The ready solution must be injected immediately or stored in the refrigerator for up to 24 hours. It is usually recommended that the compound be stored in the refrigerator. With the exception of the remedy Saizen the biological activity of growth hormones is usually not impaired when storing the dry substance at 15-25 C (room temperature); however, a cooler place (2-8° C) is preferable.On the black market the price for 4 I.U. each of the compounds Genotropin, Humatrope, Norditropin, and Saizen, in Europpe is $80-120 for a prick-through vial including the solution ampule. As already mentioned, there are many fakes. It is noted that for the U.S.-American growth hormones compounds, the substance content is not given in I.U.(International Units) but in mg (milligrams).

Since l mg corresponds to exactly 2.7 I.U. the 5mg solution of the compound Humatrope by Lilly contains exactl 13.5 I.U. of Somatropin. The 10 mg solution of the Protropin compound by the Genentech therefore contains 27 I.U. of Somatropin.

In American powerlifting and bodybuilding circles Humatrope is usually preferred over Protropin. The reason is that Humatrope is synthesized from a chain of 191 amino acids and thus is identical to the amino acid sequence of the human growth hormones. Protropin, on the other hand, consists of 192 amino acids, one amino acid too many. This might be the explanation for why more antibodies are developed with Protropin than with Humatrope. growth hormones are on the doping list but they are not yet detectable during doping tests.

Jintropin (HgH – Human Growth Hormone)

HGH is being produced by pituitary gland in the human body. This peptide plays vital role in human body and is responsible for many different things, including muscle and bone development. As one gets older, the level of endogenous HGH in the body decreases. Normal growth is impossible without this hormone and it acts throughout the whole life. Jintropin HGH injections are still beneficial for adults, especially to competing sportsmen. For elderly people HGH replacement therapy is a part of anti-aging therapy. Injections raise HGH levels back to the youth-like ones thus improving muscle growth, weight loss and defeating aging.

Jintropin  is one of the purest and the most famous recombinant human growth hormone (rHGH) brands, it’s quality is par to very expensive American-made Humatrope although notably cheaper. Jintropin kit contains 10 vials, each one 10IU or 4 IU  (this is new version) thus making 100IU or 40IU per kit, respectively.

Jintropin comes as a white lyophilized powder (it should not look as a distinct disk) consisting of the 191 amino acids sequence identical to endogenous human growth hormone. Various HGH brands differ in quality (purity) of substance, the more pure it is the less is possibility of developing antibody resistance, which may in theory decrease effectiveness of the drug. Some of the cheapest rHGH brands consist of 192 amino acids formula, which differs from natural. It works more or less for vast majority of people but for some could be completely ineffective. There’s also liquid version called Jintropin AQ.

Jintropin export from China officially ceased since Spring 2008 due to US pressure on Chinese government in connection with Olympic Games. Most of Jintropin on the Western over-the-counter market is fake! Only big pharmaceutical companies with official import license are able to purchase from GenSci now. Therefore, you can find this product only with prescription in legal retail pharmacies, not from various overseas online stores. However, we do not say that absolutely all Jintropin on the black market is fake. There is still limited number of channels available through domestic Chinese resellers at huge price.

The website of the manufacturer is GeneScience Pharmaceutical Co., Ltd.  and their code-checking center A clone website is FAKE and has no relation to Gensci, as well as plenty of other fake sites.

Peptides play vital role in human’s body and are related among themselves in various ways. HGH is a part of following chain GHRH (or artificial CJC-1295 with DAC hormone) -> HGH->IGF1->MGF. Growth Hormone Releasing Hormone initiate producing of HGH. HGH itself has several positive effects and also works by increasing the volume of another peptide called IGF-1 (insulin-like growth factor) . IGF-1,in turn, increases the number of muscle cells and produces MGF (mechano growth factor), which works towards repairing damaged cells. As a result muscle density is notably increased, body fat decreased and ageing process is being slowed down.

Combinations like CJC-1295 plus GHRH-6 or HGH along with IGF-1 Long R3 or HGH+IGF-1 LR3+MGF at sufficient dosages  produces unbelievable synergetic effect, which could not be reached simply by increasing HGH dosage. Most likely the reason is maintaining higher and more stable hormone levels in the blood for a long time, which is impossible to maintain with HGH only due to quite short halflife. However, in most occasions even using HGH standalone at proper time of a day is sufficient to reach athlete’s goals, one just must consider level peaks and downs.

After puberty, it became more difficult to increase number of muscle fibers, training mostly increases number of muscle cells for existing fibers or their volume due to water retention. HGH assists in raising levels of IGF-1 back to their pre-pubescent level, hence helping muscle fibers to split and creating new ones thus making more relief and more determination of all muscles.

HGH allows athletes to develop and maintain the ideal muscle density. Unlike steroids which may cause you to gain so-called water weight, it promotes only lean muscle growth. Thus HGH indirectly but very effectively increases lean body mass, shortens recovery time in-between workouts, and enhances the overall performance with less risk of detection than steroids. In addition, it strengthens joints and ligaments and cures damaged tissue. Also HGH promotes protein synthesis abilities, increases volume of insulin a body can effectively use. It well complements steroids improving their effectiveness, so in most cycles HGH comes together with anabolics.

HGH raises person’s energy levels and increases metabolism, so adults can benefit the same energy as they did when they were young. An increased metabolism also means an increased burning of fat. In fact, HGH (Jintropin and other brands) can cause weight loss even without exercise.


Human growth hormone is one of the most effective drugs in this area. With age production of all hormones including HGH falls down, body becomes less and less able to repair damaged cells and produce new ones. HGH improves cells restoration as well as new cells production thus making it useful virtually in any system of the body. Jintropin HGH promotes smoother and less-wrinkled skin by repairing damaged skin cells. Also it helps in strengthen bones , even those that have been damaged by osteoporosis. In addition, it can repair damaged brain cells and hence prevent memory loss. It’s anabolic (muscle-improving) effects have been already discussed.

HGH History

Human growth hormone is not new thing in medicine. Some major pharmaceutical companies have been manufacturing HGH for many, many years. However, it was extremely expensive and only prescribed to the children with low or non-existent endogenous HGH. Bodybuilders have to acquire it on the black market; Jintropin is very potent brand of HGH, it is similar to American brand Humatrope, but much less expensive.

HGH in the sport (bodybuilding)

HGH provides plenty of benefits to the athletes. It’s safer than using steroids and it well complements steroid cycles. Human Growth Hormone stimulates growth of many body tissues, mostly due to increase in cell number rather than size. This includes skeletal muscle tissue, and with the exception of eyes and brain all other body organs. It improves the transport of amino acids, as well as the rate of protein synthesis.

Actually, most of these positive effects are caused by IGF-1 (insulin-like growth factor). This is  a highly anabolic hormone produced in the liver and other tissues in response to GH. Maximum levels of IGF-1 are observed approx. 20 hrs after HGH administration. HGH itself stimulates triglyceride hydrolysis in adipose tissue, which leads to notable melting of fat. Also it increases glucose output in the liver, and induces insulin resistance by blocking the activity of this hormone in target cells. A shift is seen where fats become primary source of energy, further enhancing fat loss.

Strength of connective tissues, cartilage and tendons is also enhanced thus reducing possibility of injures during training with heavy weights.

Usage of HGH

This is very dosage-dependent drug. Using low dosages or low frequency of injections is a waste of money!  Also, it should be applied long enough to become effective – 8-12 weeks at least, better more. If you fail to meet these requirements, the results will be very poor. If you cannot afford full-scale HGH cycle, you should really avoid using it.

The average male athlete daily dosage ranges between 5 to 10 I.U. to achieve the best results. On the low end perhaps 2 to 6 I.U. can be used ED (or 8 I.U. EOD, administered during ‘training’ days).

Daily dosing is important, as HGH has a very short life span in the body. Peak blood concentrations are noted quickly (2 to 6 hours) after injection, and the hormone isquickly cleared from the body with a half-life of only 20-30 minutes. Some athletes advise using it EOD (duplicate dosage) as it is more effective like this. The trick is to use it during workouts, not days-off. If you are using let’s say 5 IU ED then EOD dosage comes to 10 IU.

The effects of this drug are also most pronounced when it is used many months long. Shorter HGH cycles (4 weeks) are effective for fat-burn but not muscle-growth.

This drug can be injected both – intramuscular and subcutaneous. “Sub-Q” injections produce localized melting of fat, thus requiring to change injection spots to even out the effect. General fat-burn also takes place, it appears more quickly and is less dependent on dosage.

Although it’s not absolutely necessary, using of supplemental drugs could produce even better effects. HGH injections suppress endogenous thyroid and insulin production, while your body requires increased amount of thyroid hormones, insulin and androgens during treatment.

Adding thyroid hormones like T3 (cytomel, tiromel brands) and T4 (synthroid) also known as liothyronine and levothyroxin substances, will greatly increase the thermogenic effectiveness of a cycle. The more powerful T3 is usually preferred at daily dosage of 25 mcg.

Insulin could be also very useful. Aside from replacing lowered insulin levels, use of this hormone is important as it can increase receptor sensitivity to IGF-1, and reduce levels of IGF binding protein-1 thus allowing more free IGF in the blood.

Adding HGH derivatives – IGF (Insulin-like Growth Factor) and MGF (Mechano Growth Factor) to the cycle produces synergetic effect.

Steroids also proved to be very effective to benefit full anabolic effect of HGH. It’s better to use something with a strong androgenic component, for instance testosterone or trenbolone (parabolan) if estrogen levels matter. While HGH increases cell count, androgens increases cell volume. Using of AAS may also increase free IGF-1 levels.

The combination of all mentioned drugs – HGH (maybe along with IGF/MGF), anabolic steroids, insulin and T3 proved to be the most effective combination with great synergetic effect and clearly amplified results. However, one should always consider potential risks related to the usage of thyroid hormones and insulin, which could cause serious health problems unless used wisely.

Resume: HGH could very effective drug if athlete well understands what he is using it for. Standalone it will not turn you into “freaky monster”, if all you need is mass – better go to classic bulking steroids. If you need to cut down – better use special fat-burning drugs. Also, if comparing $ to $ investments, anabolic steroids could do the job cheaper. Using peptides and especially HGH is like a different side of coin with its own pros and cons – more expensive and less sides.

The most prominent results are achieved when combining both types of products – one can benefit from great shape, excellent  physique and marvelous performance. But for an amateur sportsmen using of HGH is often like overkill, it mostly necessary for competing athletes where substantial investments are well justified.

More quality HGH brands like Jintropin act much quicker than let’s say Serostim with regards to the results.


Anti ageing: feeling of well being, some moderate fat-burn, improved skin appearance – 2 IU daily
General treatment: moderate fat-burn, improved sleep, more energy: 3 IU daily
Fitness: improved muscles, advanced fat-burn – 4 IU/ED
Sport: muscular hypertrophy, great feeling of a wellbeing, superman energy – 5 IU and more daily. Duplicate dosage could be administered EOD during workouts.

Daily dosage for more effect should be better split on two shots – 8 a.m. (or after wake up) and approx 1 p.m. (or after workout, but not too late). Do not admiister before sleep – it’s a waste. Such schedule allows to get the most profit from combination of endogenous and exogenous Growth Hormone. If splitting is not possible – inject it all in the morning

Side effects

Hypothalamus releases GHRH (growth hormone releasing hormone, i.e. precursor of GH) and SST (somatostatin). They both stimulate or inhibit the output of GH by the pituitary. GH has direct effects on many tissues, as well as indirect effects via the production of IGF-1. IGF-1 also causes negative feedback inhibition at the pituitary and hypothalamus. Therefore, heightened release of somatostatin affects not only the release of GH, but insulin and thyroid hormones as well.

Human Growth Hormone by itself carries certain risks. The most feared and the most discussed side effect would be acromegaly, or a noticeable thickening of the bones, especially the feet, forehead, hands, jaw and elbows. The drug can also enlarge vital organs such as heart and kidneys, and has been linked to hypoglycemia and diabetes (presumably due to its ability to induce insulin resistance). In theory, excessive usage of this hormone can lead to a number of conditions, some of them life threatening. Fortunately, such problems are extremely rare and unlikely to occur if used periodically in moderate dosages. Among the many athletes using growth hormone, there are very few documented cases of a serious health problems developed.

Of course, if there are any noticeable changes in bone structure, skin texture or normal health conditions HGH therapy must be ceased immediately.

Detection and doping control.

Not long ago it was absolutely “safe” drug for testing. However, recently some test have been invented. It’s difficult to evaluate yet how accurate they are and how long is detection time (must be very short, like several days). However, HGH is still advisable for competing athletes, risks are much less comparing to using of steroids.


Although this was a big issue in the past, most of modern HGH brands could sustain under room temperature for about a month thus making transportation possible without using dry ice as it was in the past. It is still recommended, however, to decrease “hot” time as much as possible and keep it refrigerated between 2 – 8 degrees Celsius. But never freeze!

For instance, Eurotech brand cannot be kept at room temperature indeed, while Jintropin™ is made according to a special patented technology, so it can withstand temperatures up to 37 degrees Celsius for over a month and 45 degrees Celsius for over a week, which is incredible, unbelievable time. In proper storage conditions it’s good for over a year (until exp. date indicated on the package).

After reconstitution liquid has to be refrigerated. With Jintropin maximum storage time comes to 20 days, with other brands 2-5 days.


Water for solution always comes with more expensive Growth Hormone kits, with cheaper brands you have to acquire it separately. When mixing HGH and other peptides into solution, two types of water could be used – either sterile or bacteriostatic one.

Sterile (distilled) water solution meant to be used within a 48 hour period. Bacteriostatic water contains very small volume of acid which allows Growth Hormone to be kept for a longer period of time. The acid makes the bond between the molecules more stable. The sterile water just weakens this bond quickly thus making molecules to become unstable.


For peptides it’s more convenient to use insulin syringes. At-first, they have thin and convenient for this purpose pin. At-second, the syringe itself allows much more precise measuring than “regular” syringes.

1 ml insulin syringe contains 100 marks (100 “clicks”). When you dissolve full HGH bottle in this volume, you can count how much to inject.

Hygetropin 8 IU bottle – every click equals 0.8 IU. In order to make 4 IU injection you have to utilize half of the syringe, i.e. 50 clicks

Jintropin or Kigtropin 10 IU bottle: In this case, every 10 clicks equals 1iu, for 4 IU injection you have to use 40 clicks.


When mixing water with the powder always release it slowly downside the glass. This ensures that the compound remains intact since HGH molecule is long and fragile. Once you filled it with water, gently swirl the solution until dissolved. NEVER SHAKE!


It is to be injected virtually anywhere, preferably sub-q. The inner thigh is the area which suits the most for good absorption although many people prefer abdomen area instead due to convenience of the process (however, fat may slow down absorption).

When injecting sub-q set a needle at 45° angle towards the skin surface, carefully pinch a small fold and inject in the middle.


Growth Hormone does not directly causes muscle growth, it rather works indirectly by increasing protein synthesis capabilities as well as  increasing volume of insulin and anabolics a body can utilize effectively. HGH might be considered as a precursor to IGF while IFG is a precursor to MGF. Each of them could be used standalone although IGF is a bit more effective in direct effect caused to muscle growth and increasing muscle density. It’s difficult to say if any product is “better”. Combining two or all of them together could bring marvellous synergetic effect, just make sure to use versions, which are stable in the blood – Long R3 IGF-1 and pegMGF (pegylated).

GenSci ceased export in 2008 under US pressure in connection with the Olympic Games. Most (although not all) of Jintropin available nowadays on the over-the-counter market is fake. Consider using other top pharm-grade products like Saizen HGH
