Test Cyp is one of the most well known testosterone steroids, with a capacity to act faster in the body compared to other kinds of steroids. It is an injectable and is not available in an oral form meaning that it reaches the bloodstream faster and its effects can therefore be seen faster. The difference between Test Cyp 250 and other testosterones is that Test Cyp 250 has been made for slow release into the bloodstream compared to other steroids. This has a good effect in that it will last longer in the body compared to other steroids. This may not be the case when it comes to other steroids which do not necessarily last long in the body compared to testosterone cypionate.
