Testosterone Propionate is an excellent anabolic steroid. It is highly versatile, tremendously beneficial, well-tolerated by most all adult men and affordable. The added propionate ester will slow the rate in which testosterone is released from the injection site. Testosterone propionate is, therefore, comparatively much faster-acting than other testosterone esters such as cypionate or enanthate, and requires a much more frequent dosing schedule. Still, those who are not bothered by the frequent injection schedule find testosterone propionate a powerful mass building drug, capable of producing rapid gains in both muscle size and strength.
