Testosterone Cypionate 250mg (#540048) – Effective Muscle Growth & Performance Booster

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 later. The difference in Testosterone Enanthate and Testosterone Cypionate is largely inconsequential.
