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. Without an ester, the hormone would disperse and dissipate rapidly post administration. By attaching the ester, this promotes a controlled release and allows the individual to inject the hormone less frequently. Once Testosterone Propionate is injected, the ester slowly begins to detach from the hormone. As the ester is detached the testosterone hormone begins to release into the blood. The half-life of Testosterone Propionate is approximately two days, which is substantially longer than ester free testosterone, which carries a half-life a little less than 24 hours.
It’s no secret there exist a strong anti-steroidal population and as this “anti” feeling is often so emotionally based it can produce some laughable claims. If you’ve been around the performance enhancing game for any length of time you’re familiar with all the names and acronyms so this will probably make you laugh. Yes, there are a few street names for steroids such as juice or roids but those are some very generic terms and really don’t point to anything specific. We went to a handful of the anti-steroid websites so desperate to paint anabolic hormones in a bad light and they have made up their own street names for steroids that are quite humorous and they include “Pumpers, Gym Candy, Arnolds, Stackers, Balls and Bulls, A’s, Weight Trainers.” “Weight Trainers” are you serious, Arnolds? If that didn’t make you laugh a little then you don’t have a sense of humor but the sad truth is these websites are real and many of them are funded by your government.
Testosterone Propionate often referred to as just “prop” test-p or “test prop” is a version of testosterone that promotes nitrogen retention in the muscle (6), and the more nitrogen the muscles hold the more protein the muscles store, and the bigger the muscles get. Testosterone Propionate can also increase the levels of another anabolic hormone, IGF-1, in muscle tissue. IGF-1 is alone highly anabolic and can promote muscle growth . It is responsible for much of the anabolic activity of Growth Hormone (GH). IGF-1 is also one of the few hormones positively correlated with both muscle cell hyperplasia and hyperphasia (this means it both creates more muscle fibers as well as bigger fibers).
