Testosterone Enanthate is one of the oldest
and perhaps the most commonly used anabolic steroid of all time.
Testosterone Enanthate is a slow acting release form of the testosterone
hormone and would be the first large/long ester testosterone form used.
Synthetic testosterone itself would be developed in the 1930’s. The
first batches of testosterone manufactured would have no ester attached
(Testosterone Suspension) and needless to say would be fast acting and
require very frequent injections. In 1937 the first ester controlled
testosterone would hit the market thanks to Schering and their new
Testosterone Propionate product. This would allow for more control over
the testosterone hormone by regulating its time release. However, in the
early 1950’s a larger ester in Enanthate would be attached to the
hormone thereby slowing down the hormone’s activity even more.
Testosterone Enanthate would become the dominating testosterone form in
the medical field and Testosterone Cypionate would join a few years
