Testosterone propionate is a commonly manufactured injectable form of the primary male androgen testosterone. The added propionate ester will slow the rate in which testosterone is released from the injection site, but only for a few days. 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. By most accounts testosterone propionate is an older and cruder form of injectable testosterone, made obsolete by the slower-acting and more comfortable esters that were developed subsequent to it. Still, those who are not bothered by the frequent injection schedule find testosterone propionate every bit as acceptable. As an injectable testosterone, it is a powerful mass-building drug, capable of producing rapid gains in both muscle size and strength.

How to use : The usual dosage among male athletes is in the range of 50-100 mg per injection, which is given every second or third day. Similar to other esters of testosterone, testosterone propionate is commonly used at a weekly cumulative dosage between 200 mg to 400 mg. This level is sufficient for most users to notice exceptional gains in muscle size and strength.
