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.
Testosterone propionate is a commonly manufactured, oil-based injectable testosterone compound. The propionate ester will slow the rate in which the steroid is released from the injection site, but only for a few days. Testosterone propionate is therefore much faster acting than other testosterone esters such as cypionate or enanthate, and requires a much more frequent dosing schedule, in order to maintain stable blood levels. While cypionate and enanthate are injected on a weekly or bi-weekly basis, propionate is usually injected every second. The propionate ester can be very irritating to the site of injection. In fact, many sensitive individuals choose to stay away from this steroid completely, their body reacting with a pronounced soreness and low-grade fever that may last for a few days.
