Testosterone is the major and most important male androgen in the body, which carries many important functions, one of them is muscle growth. This makes testosterone the first steroid for bodybuilding. There is simply nothing more powerful.
Sustanon 250 is a trade name for an oil-based injectable blend of four esterized testosterone compounds:
- 30mg Testosterone Propionate
- 60mg Testosterone Phenylpropionate
- 60mg Testosterone Isocaproate
- 100mg Testosterone Decanoate
Sustanon 100 is similar, though with three esters. The smaller dose is for paediatric use.
- 20mg Testosterone Propionate
- 40mg Testosterone Phenylpropionate
- 40mg Testosterone Isocaproate
The different testosterone esters provide for different half lives. Esterization of the testosterone molecules provides for a sustained (but non-linear) release of testosterone from the injection depot into the blood plasma.
While the intention of the mixed testosterone esters in Sustanon is to provide more stable serum testosterone levels, a single long-ester testosterone, such as testosterone cypionate or testosterone enanthate, may actually provide more stable serum testosterone levels.
Sustanon is a fairly popular anabolic steroid product among those that use anabolic steroids for muscle building purposes.
The mixture of the testosterones are time-released to provide an immediate effect while still remaining active in the body for up to a month. As with other testosterones, Sustanon is an androgenic steroid with a pronounced anabolic effect. Therefore, athletes commonly use Sustanon to put on mass and size while increasing strength. However, unlike other testosterone compounds such as cypionate and enanthate, the use of Sustanon leads to less water retention and estrogenic side effects. This characteristic is extremely beneficial to bodybuilders who suffer from gynecomastia yet still seek the powerful anabolic effect of an injectable testosterone. The decreased water retention also makes Sustanon a desirable steroid for bodybuilders and athletes interested in cutting up or building a solid foundation of quality mass.
Dosage and usage
Inject 1-2 times a week (two times is better to make levels more stable), preferably into big muscles like upper leg or buttocks. Rotate injection spots to prevent inflammation.
Dosages of Sustanon range from 250 mg every other week, up to 2000 mg or more per week. These dosages seem to be the extremes. A more common dosage would range from 250 mg to 1000 mg per week, novice do 250 mg/w, "regular" user 500 mg/week, higher dosages are for competing sportsmen.
A steroid novice can expect to gain about 20 pounds within a couple of months by using only 250 mg of Sustanon a week. More advanced athletes will obviously need higher dosages to obtain the desired effect.
Testosterone is very powerful substance by itself to allow standalone Cycles. So 500-1000mg of testosterone will produce notable results over 8 or better 10 weeks cycle whether used in combo or standalone. Testosterone has so many different activities that other steroids serves merely as an additional supplement. However, stacking is necessary if athlete have serious goals. It helps to reduce the quantity of testosterone and thus negative side effects by adding some milder substances like Primobolan Depot (Methenolone Enanthate), Nandrolone Decanoate (Deca-Durabolin) or Boldabol (Equipoise).
Testosterone is in fact an ideal partner for any other steroid because of its action on androgen receptor in muscle cells and it’s possible to combine it virtually with everything. The best results, however, are achieved when sustanon is combined with Nandrolone Decanoate esters, methandrosterolone or Anadrol/Anapolon (Oxymetholone). Combination of sustanon + Nandrolone phenilpropionate + Methandrosterolone provides bulking "super action". Stacking of testosterone with Trenbolone or Boldabol (Equipoise) produces great results as well.
As it was mentioned before, you can stack testosterone virtually with everything, but Nandrolone Decanoate, Primobolan Depot (Methenolone Enanthate) and Boldabol (Equipoise) are the best options for bulking cycles. As for other gear – you should consider what kind of effect they can add. For instance Anavar (Oxandrolone) will add some strength and might be used in pre-competition cycle when bulking is not necessary. If you are looking only for mass – you may simply increase testosterone dosages and no need to add other compound UNTIL side effects will prevail. Only after this it worth stacking (or if you are looking for milder cycle from the beginning). To explain this thought read following example. For instance, someone wants purely bulking cycle. He tried once, did 250 mg/week and was not satisfied with the results. What to do next time? Not ideal decision would be 250 mg of test in combo with 400 mg of deca. Ideal and simple decision 500 mg of testosterone /week. Another example, someone is looking for a moderate bulking cycle. Not too weak, not with a lot of side effects as well but rather something on the middle. A possible solution is 250 mg of testosterone/week and 200 mg of boldenone/week with PCT, of course. Hopefully you understood what author means.
Common length of sustanon cycles is 8-10 weeks.
A popular "mass" stack is 500 mg of sustanon / week + 400 mg of Nandrolone Decanoate (Deca-Durabolin) / week and strong PCT – you need anti-estrogen during and after cycle and you need to boost natural production afterwards.
For those who are looking for milder bulking stack – the same testosterone dosage in combination with Primobolan Depot (Methenolone Enanthate) 400-600 mg/week is an option. It makes cycle much safer although gains will be also lower because Primobolan has lower anabolic properties comparing to deca, it’s main advantage is non-aromatization. As we already mentioned low estrogen level leads to lower mass gains although the gains you receive will be more lean and dry. Another disadvantage is high price of Primobolan. PCT and anti-estrogen are still needed as always with testosterone.
Third option is sustanon with Boldabol (Equipoise) 200-400 mg/week, which is stronger than Deca-Durabolin and has lower side-effects. This is still bulking stack, however, Boldenone Undecylenate provides more lean and dry mass gains, which is similar to positive effects of Primobolan Depot (Methenolone Enanthate), although much stronger. Furthermore, Boldenone promotes appetite, which is often suppressed by usage of testosterone thus making your nutrition more effective.
Sustanon is a fairly safe steroid, but in high dosages, some athletes may experience side effects due to an elevated estrogen level. With dosages exceeding 1000 mg a week, it is probably wise to use an antiestrogen such as Zymoplex (Tamoxifen Citrate, Nolvadex) or Proviron (Masterlone). The use of Sustanon will suppress natural testosterone production, so the use of HCG (human chorionic gonadotropin) or Clomiphene (Clomid) may be appropriate at the end of a cycle. Sustanon 250 is a good base steroid to use in a stack. Athletes interested in rapid size and strength gains find that Sustanon stacks extremely well with orals such as Anadrol/Anapolon (Oxymetholone) and Dianabol (methandrostenlone). On the other hand, Sustanon also stacks well with Trenabol Depot (trenbolone hexahydrobencylcarbonate), Mastabol (drostanolone propionate), and Winstrol (Stanozolol) for athletes seeking the hard, ripped look. Sustanon 250 is quite abundant on the US black market.
Sustanon will do exactly what other forms of testosterone will do:
Testosterone will cause both muscle growth as well as fat loss. It sends a message to muscle cells to store more contractile protein (called actin and myosin), thus making your muscles grow. It also protects your muscles from catabolic (muscle wasting) glucocorticoid hormones. Thus it is often said that testosterone is not only anabolic, but it is strongly catabolic. Not only does it cause an increase in size of the muscle fibbers (hyperfascia) but it also can change the appearance and the actual number of muscle fibbers (Hyperplasia). Testosterone has the ability to increase erythropoiesis (red blood cell production) in your kidneys, and a higher Red Blood Cell (RBC) count may improve endurance by producing more highly oxygenated blood. More RBCs can also improve recovery from strenuous physical activity. Aggression levels often rise dramatically with the use of any exogenous testosterone . Testosterone improves muscle contraction by increasing the number of motor neutrons in muscle and improves neuromuscular transmission. It also promotes glycogen synthesis
And, since Sustanon is simply a form of (well actually 4 forms of) testosterone, the more you take, the bigger you get… This is true of Sustanon as well as for every form of testosterone, up to a point.
Unfortunately, Sustanon will also do all of the bad things that any form of testosterone is known for:
It will convert to the female hormone estrogen (via a mechanism known as aromatization) by the (you guessed it) aromatize enzyme. Excessive estrogen can lead to unwanted side effects, such as acne, the growth of breast tissue (gynecomastia), fat gain and reduced fat breakdown, loss of sex drive, testicular shrinkage and water retention. Water retention can increase blood pressure weakening blood vessels over time. Unfortunately, this isn´t all it does& it can also interact with the 5 alpha-reductase enzyme. This interaction converts the testosterone to Dihydro-testosterone (DHT), a more androgenic form of the parent hormone. DHT has a high binding affinity to the tissues of the scalp resulting in hair loss in loss in users who suffer from male pattern baldness. DHT can affect the prostate as well, making it larger. This swelling can cause the gland to press against the bladder causing urinary problems. Drugs called 5 alpha-reductase inhibitors can prevent these symptoms without blocking testosterone´s anabolic effects. Higher dosages of test can also negatively impact cholesterol, lowering HDL. Testosterone is probably the safest steroid around, but it can´t be taken lightly, and Sustanon is no different.
It has long detection time as most of testosterones, especially long-acting ones. Doping tests can find it up to three months after the cycle.
Side effects and PCT (Post Cycle Therapy) with testosterone Enanthate
Since testosterone is easily aromatized, its use in high doses may cause side effects such as water retention, acne, female-pattern fat deposits, and gynecomastia ("bitchy tits"). But for most athletes these problems start at high doses of the drug – from 1 gram (1000mg) per week or more. Therefore, it is advised to take some anti-estrogen like arimidex, proviron, tamoxifen or clomiphene. At dosages of 500-600 mg per week, side effects are normally low, but some people are more prone (more sensitive) to these side effects than others, so if problems arise, do 1 tab of clomiphen 50mg or tamoxifen 20mg until problem disappear.
The conversion of testosterone to DHT means a risk of such androgen-related side effects as baldness and prostate enlargement. Again, this only applies to high dosages or to the people with high level of 5-alpha-reductase enzyme.
The use of testosterone, even at doses of more than two grams (2000mg) a week not infringe either the liver or other organs. Recovery of natural testosterone production after a cycle is normally quick and successful.
PCT: 25-50mg of arimidex/day OR 25-50 mg of proviron/day during the cycle. Normally 25 mg is just fine but in case of "heavy" cycles dosages up to 100 mg of proviron might be required. Actually, it’s better to use proviron instead of arimidex along with the testosterone injections since it increases volume of free testosterone in the blood thus promoting gains. Athlete should also consider the following thing – estrogen converted from androgen plays very important role in muscle gains. Thus, more anti-estrogen you use – there are less estrogen-related side effects but also less gains. So, you have to find experimentally what suits the best to your body. People who worry more about gains should use minimal dosage of anti-estrogen, people who worry more about estrogen level should use higher one.
Some people are more concerned about androgen-related side effects such as deep voice, baldness, prostate hypertrophy. These ones should do 1 tab/ED of a product named finasteride (brand names propecia, proscar, fincar, etc.), which blocks 5-alpha-reductaze and thus conversion of testosterone into more aggressive androgenic substance DHT. Again, one should find a balance. DHT is more powerful androgen, maybe 300% stronger than testosterone and it’s positive effects increases along with unwanted side effects. Also, keep in mind that if you are more concerned about androgen-related side effects, you should not use proviron, which is in fact very similar to DHT. Better use arimidex as anti-estrogen in that case.
As you may see, all these things – testosterone, dihydrotestosterone, estrogen and androgen levels, estrogen blockers, etc. are highly related and dependant on each other so there is no single advice for everyone, you should consider what is more important exactly for you and choose appropriate anti-estrogen and dosage basing on it.
When the cycle is over, natural testosterone production is severely suppressed and needs to be restored, otherwise much of gains will be lost and also you’ll have problems with libido and shrinkage of testicles, which is especially true for long cycles. Many bodybuilders of 70es, when steroid science was not so developed felt all these side effects and became big and fatty or small and tiny or had heart problems (heart is also a muscle) which leaded to all these horror stories and prohibition of steroids in many countries. Fortunately, now we all know how to make it safe. Using Human Chorionic Gonadtropin (HCG, Pregnyl) and tamoxifen (nolvadex, cymoplex, cytotam) / clomiphene (clomid, fertomid) plays key role in Post Cycle Therapy. Let’s say 40 mg (2 tabs 20 mg) of tamoxifen equals 150 mg (3 tabs 50 mg) of clomiphene). People still argue, what is more effective. Many people believe tamoxifen is better during cycle and clomiphen is better after it. However, there are also opposite opinions, so if you are in doubts combine tamo+clom during PCT after the cycle is over.
One should start HCG injections on the last week of cycle and do 1500-3000 IU every 5-7 days depending on testosterone dosages during the cycle. HCG serves as an alternative to natural LH, it will boost testosterone production in the body thus restoring size of testicles back to normal. HCG should be used for 2-4 weeks in total. However, it does not eliminate the problem but serves just as a "bridge" between the cycle and post-cycle healers (tamo/clomid). Although it "orders" to the body to start producing testosterone, this is not "natural" production. In fact it even suppresses natural production of the hormone, and usage of HCG should be stopped two weeks before you finish tamoxifen / clomiphen.
Using HCG is strictly advisable, but if you don’t have it, just start with higher then described below clomiphene/tamoxifene dosages, let’s say 3-4 tabs/ED for two weeks.
Two weeks after the cycle (if HCG has been used) start doing 2 tabs of tamoxifen 20 mg or 3 tabs of clomiphene 50 mg or combination of both for two weeks. After this, do two more weeks with 1 tab of tamoxifen or two tabs of clomiphene daily.
A conclusion: Arimidex or Proviron fight estrogen during cycle, tamoxifen and clomid finish this job and also boost natural testosterone production. HCG helps to smoothen critical testosterone production downfall right after the cycle.
It is strictly not advisable for females with normal testosterone level to use testosterone injections for sport-related purposes. External testosterone will simply lead to virilization effects, so women in bodybuilding should stay away from it. There are different ethers like testosterone undecanoate, which fit well for them.
