Testosterone Propionate is a pure testosterone hormone. Although synthetic it is a perfect replica of the primary naturally produced male androgen testosterone. By design, the hormone is attached to the Propionate (propionic acid) ester, a small/short ester that enables the hormone’s release time to be controlled.
Testosterone propionate, or test prop as the gym bros may call it, is currently the shortest-ester testosterone steroid available on the black market.
Testosterone propionate, sold under the brand name Testoviron among others, is an androgen and anabolic steroid (AAS) medication which is used mainly in the treatment of low testosterone levels in men. It has also been used to treat breast cancer in women. It is given by injection into muscle usually once every two to three days.
Testosterone Propionate is an injectable testosterone dissolved in oil with an attached propionate ester. The propionate is a so-called “short-term ester”, which means that on the one hand it gives a rapid onset of action, but the half-life on the other hand is relatively short.
Because Testosterone Propionate is a slower releasing anabolic steroid with a shorter half-life of 4.5, it holds the capability for allowing users to run short Testosterone Propionate cycles in the range of 8 – 10 weeks (and sometimes as short as 6 weeks).
Within medicine, Testosterone Propionate is primarily utilized for the treatment of androgen deficiency in adult males (hypogonadism or andropause).The original prescription guidelines stated that Testosterone Propionate doses for such a condition are that of 25mg 2 – 3 times weekly.
Testosterone Propionate is the shortest commonly ester attached to the Testosterone hormone. This means it takes your body the least amount of time to rid itself of the ester and release the parent hormone into the body. Due to its short active life, testosterone propionate typically needs to be injected every other day at a minimum.
