Testosterone blend typically contains four different testosterone esters: Testosteronepropionate (30 mg); testosterone phenylpropionate (60 mg); testosteroneisocaproate (60mg); and testosterone decanoate (100 mg), although alower dosed version is also produced. An intelligently "engineered"testosterone, Sustanon is designed to provide a fast yet extendedrelease of testosterone. The propionate and phenylpropionate esters inthis product are quickly utilized, releasing into circulation withinthe first four days. The remaining esters are much slower to release,staying active in the body for about two and three weeks (respectively).

Aswith all testosterone products, Sustanon is a strong anabolic withpronounced androgenic activity. It is mainly used as a bulking drug,providing good gains in strength and muscle mass. Although it doesconvert to estrogen, as is the nature of testosterone, this injectableis noted as being slightly more tolerable than cypionate or enanthate.Such observations are only issues of timing however. With Sustanon,blood levels of testosterone are building more slowly, so side effectsdo not set in as fast. For equal blood hormone levels however,testosterone will break down equally without regard to ester. Alsocorrelating with estrogen, water retention would be noticeable withSustanon, unless steps were taken to minimize estrogen.
Manyindividuals like to use a combination of Nolvadex & Proviron, whileothers use an anti-aromatase like Arimidex, Femara, or Aromasin, tohelp control estrogen related side effects.

Being a strongandrogen, we can expect the typical side effects. This includes oilyskin, acne body/facial hair growth and premature balding. The additionof Proscar/Propecia should be able to minimize such side effects, as itwill limit the conversion of testosterone to DHT (dihydrotestosterone). Sustanon will also suppress natural testosterone production ratherquickly. The use of HCG and/or Clomid/Nolvadex are necessary at theconclusion of a cycle in order to avoid a hormonal crash. Rememberthough, Sustanon will remain active in the body for up to a month afteryour last injection was given. Beginning you post cycle drug therapyimmediately after the steroid has been discontinued will not be veryeffective. Instead, HCG or Clomid/Nolvadex should be delayed threeweeks, until you are near the point where blood androgen levels havedropped significantly.

Although Sustanon remains active in thebody for approximately three weeks, injections are taken at least every10 days. An effective dosage ranges from 250mg (one ampule) a week, to1000mg (four ampules) weekly. Some athletes do use more extreme dosagesof this steroid, but this is really not a recommended practice. Whenthe dosage rises above 750-1000mg per week, increased side effects willno doubt be outweighing additional benefits. Basically you will receivea poor return on your investment, which with Sustanon can besubstantial. Instead of taking unnecessarily large amounts, athletesinterested in rapid size and strength will usually opt to additionanother compound. For this purpose we find that Sustanon stacksextremely well with the potent orals Anadrol and Dianabol. On the otherhand, Sustanon may work better with trenbolone or Winstrol if theathlete were seeking to maintain a harder, more defined look to hisphysique.

Sustanon 250 is probably the most sought afterinjectable testosterone. I must however emphasize that this is not dueto an unusual potency of this testosterone combination however(remember esters only effect the release of testosterone), but simplybecause a "stack" of four different esters is a very good sellingpoint. In many instances you will get a lot more for your money withenanthate, so don't let the fancy stack fool you. Sustanon is howeverstill very abundant on the U.S. black market, and doesn't stay long ondealer's shelves. In fact the high demand for this steroid has stirrednew interest in its manufacture, particularly by veterinary companiesin Mexico.
