Testosterone is the most potent, naturally occurring androgen that is formed in the human body. It is responsible for characteristics specific to males and their sexual traits. Background Testosterone was first synthesized in 1935. Many pharmaceutical forms have been created since. Most major pharmaceutical houses such as Organon and UpJohn, manufacture Testosterone Cypionate, as do many underground labs. Steroid Action When this long-acting version of testosterone is injected, it becomes stored in what is known as a depot in the body, and slowly released over a short period of time. Peaking within 1-2 days after injection, the testosterone is then steadily released over the next 12 days and completely tapers out after approximately 3 weeks.
