Testosterone Propionate is a fast-acting steroid which requires a more frequent injection schedule in order to keep blood levels as stable as possible. Some bodybuilders also claim that Testosterone Propionate tends to induce far fewer estrogen related side effects such as bloat than do the other esters of this powerful hormone. Testosterone Propionate is the most common anabolic hormone that there is and is also considered the most basic. Due to this, bodybuilders often consider it the base steroid to most all cycles.
Testosterone Propionate is both anabolic and androgenic in nature and users of this steroid will notice a dramatic gain in muscle size and strength, as well as an overall sense of well being and increases libido and sex drive. Testosterone Propionate aromatizes very easily and therefore estrogen buildup and side effects can become an issue for users sensitive to these problems or those choosing to use a high dose of this compound. When using Testosterone Propionate, bodybuilders often choose to incorporate an anti-estrogen such as Anastrozole, Proviron, Tamoxifen to help keep estrogen related side effects to a minimum.
