Sustanon 250 is a trade name for an oil-based injectable blend of four testosterone compounds:
30mg testosterone propionate
60mg testosterone phenylpropionate
60mg testosterone isocaproate
100mg testosterone decanoate
The different testosterone esters have unique half lives. This is with the intention of providing a more stable release of testosterone to the blood.
Sustanon is a very popular anabolic steroid within the world of bodybuilding although some believe this is largely due to the marketing emphasis on its 'time-release' formula.
As with all testosterone products, Sustanon is a strong anabolic with pronounced androgenic activity. It is most commonly used as a bulking drug, providing exceptional gains in strength and muscle mass. Although it does convert to estrogen, as is the nature of testosterone, this injectable is 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 built more slowly, so side effects do not set in as fast.
is that enough research at least i know im not shooting up something like crisco haha
