Testosterone Propionate is a single ester testosterone compound and represents one of the most important testosterone compounds every manufactured. When synthetic testosterone was first created it was in its pure form. Simply put there was no ester attached, thereby providing a fast acting compound that would necessarily require a very frequent administration schedule. In 1937 the pharmaceutical giant Schering out of Germany would release the first ester base testosterone in Testosterone Propionate under the trade name Testoviron. The same trade name it would eventually give to its Testosterone Enanthate product. By attaching the Propionate ester to the hormone, this would allow for the hormone’s release time to be controlled and provided a more efficient means in maintaining stable blood levels. Although this was not the first synthetic testosterone preparation created, Testosterone Propionate would become the first commercially available testosterone product. It would also dominate the medical community until the 1960’s and much of the newly born performance enhancing community.

For the performance enhancing athlete there are so many choices and options and while many of these options have a place in just about any cycle there are very few that do in such a true and versatile way. Trenbolone is one of these anabolic steroids as positive Trenbolone effects are so pronounced in a variety of ways throughout the body. Of course it cannot be denied, the adverse Trenbolone effects can be quite brutal and for many men this makes it an anabolic steroid they absolutely cannot use; however, the majority can tolerate it quite well and if you happen to be one of these you will not find a better choice for your performance enhancing needs.
