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.

During the 1960’s Testosterone Propionate would lose a lot of its popularity in favor of the larger ester base Testosterone Cypionate and Testosterone Enanthate compounds. However, it is still used medicinally today as well as by many performance athletes.

Outside of performance enhancement, Testosterone Propionate has found a number of therapeutic uses. However, like all testosterone forms the treatment of male androgen deficiency such as low testosterone has always been the most common point of use. Testosterone Propionate has, however, also found other points of interesting use over the years in treating menopausal issues, chronic cystic mastitis, excessive lactation and endometriosis.
