Testosterone is responsible for many actions related to the reproductive system, as well. It is the hormone that is chiefly implicated in determining what sex a fetus will become in the womb. After birth, testosterone directs the development of sexual characteristics during adolescence. Bodybuilders, who often use anabolic steroids, rely on the synthetic steroid’s molecular similarity to testosterone to build muscle mass . Steroid hormones are also used in medical applications to treat hormonal disorders and deficiencies. The hormones have been proven to be relatively safe in these medical applications, but overuse has been linked to baldness , certain types of cancer, and liver disease.
While we are familiar with the Propionate ester the remaining three esters that create Sustanon-250 are almost always found as part of a mixture or compounded anabolic androgenic steroid .
Developed by Organon, the original idea behind Sustanon-250 was to provide a testosterone form well-suited for hormone replacement therapy that would only needed to be administered once every few weeks and for all intense purposes the idea was a success. For the performance enhancing athlete Sustanon-250 can be a fine choice but the idea of injecting only once or twice a month is not applicable here. As a performance enhancer this testosterone like all forms will need to be administered on a more frequent basis. This mixture carries with it two fast, short esters, Propionate and Pheylpropionate, a longer more moderate ester Isocaproate and the very slow and long Decanoate ester. In order to keep testosterone levels stable and at their peak most athletes will inject Sustanon-250 at a minimum of every 3 days and more commonly every other day for optimal results.
