Testosterone Propionate is an injectable testosterone-based steroid notable for its potency. It is essentially a blend of two esters, which means that it has greater benefits than most other steroids. What’s more, the blend of two esters gives it a long half-life and thus saves the user frequent injections. It is mostly used by body builders to increase muscle mass, but athletes also find it useful for increasing endurance.
There are various brands of Testosterone Propionate.
