Short Active Life

It acts much faster than other testosterone esters such as cypionate or enanthate, and requires a much more frequent dosing schedule, in order to maintain stable blood levels. The main function of Testosterone propionate is to promote metabolism. Anabolic effects include growth of muscle mass and strength, enhancement of bone density and strength, and stimulation of linear growth and bone maturation.

Testosterone Propionate is the shortest commonly ester attached to the Testosterone hormone. This means it takes your body the least amount of time to rid itself of the ester and release the parent hormone into the body. Due to its short active life, testosterone propionate typically needs to be injected every other day at a minimum. Anecdotally, testosterone propionate causes the least side effects and the least bloating; these side effects usually subside very quickly when use is ceased.

The major disadvantage of the short active life is that users will have to inject Test Prop at least every other day throughout its cycle to get proper results. The advantages, however, are less bloating and water retention that longer-estered products and because there is less ester in each vial, there is more actual testosterone per injection, which brings better results.
