Testosterone Caproate

Testosterone Caproate is mostly known to the steroid-using world for being the longest acting form of esterfied testosterone found in Omnadren. Other than being found in Omnadren, I'm unaware of it appearing on the legitimate pharmaceutical market. That's not to say that it hasn't appeared on the black market, as it's been available in raw hormone powder for quite some time, and several enterprising underground labs have added it to their product list.

Essentially, what we're looking at here is a long acting version of testosterone similar to enanthate, for the most part. In this specific case, the parent hormone (testosterone) is bound to a long fatty acid (the ester) to delay its release into the body. The caproate ester gives us a nice long active life in the body, and there's no reason to inject this more than once every week. In practical terms, this stuff will give you the same release and effects as testosterone cypionate or enanthate.
