Description
Sustanon 350 is an oil-based injectable testosterone blend, developed by Organon. It typically contains four different testosterone esters: Testosterone propionate; testosterone phenylpropionate ; testosterone isocaproate ; and testosterone decanoate , although a lower dosed version is also produced.
An intelligently “engineered” testosterone, Sustanon is designed to provide a fast yet extended release of testosterone. The propionate and phenylpropionate esters in this product are quickly utilized, releasing into circulation within the first four days. The remaining esters are much slower to release, staying active in the body for about two and three weeks (respectively). As with all testosterone products, Sustanon is a strong anabolic with pronounced androgenic activity. It is mainly used as a bulking drug, providing good 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 building more slowly, so side effects do not set in as fast. For equal blood hormone levels however, testosterone will break down equally without regard to ester. Also correlating with estrogen, water retention would be noticeable with Sustanon, unless steps were taken to minimize estrogen.
