Testosterone Isocaproate got its introduction to the steroid world by appearing in both Omnadren as well as Sustanon 250, the two most popular testosterone blends currently on the market.
From a purely academic point of view, I'm really at a loss to explain why the isocaproate ester would be any different than the caproate ester. It seems to have an extra day added to its active life, even though it's got the same number of carbons, hydrogens, and oxygens, as well as the same molecular weight.
As I just mentioned, this is a form of esterfied testosterone, or in other words, it's the testosterone hormone bound to a fatty acid (the ester) to delay its release into the body. The isocaproate ester has a decently long active life in the body, and consequently there's no reason to inject this more than once every week.
As with all forms of testosterone, this product will cause weight and strength gain, fat loss, a libido increase, an increase in IGF-1 levels, Red Blood Cell count, and of course increased recovery from training. It will also convert to Estrogen and Dihydrotestosterone, causing possible water retention and gynocomastia as well as acne and hairloss, respectively.
As with all forms of injectable testosterone , using this product will shut down your body's own natural production of testosterone. Also, in many cases, cholesterol, immune function, and several other health markers may be adversely affected by the use of this product.
