This is a fast acting oil based testosterone. Unlike cypionate or enanthate which are longer acting which only need to be injected once a week (depending on dosage) propionate need more frequent injections. With propionate, androgenic side effects seem somewhat less pronounced than with the other testosterones, probably due to the fact that blood levels do not build up as high. Users often report less gyno trouble, lower water retention and commonly claim to be harder on prop than with the others. Propionate is used alot in precontest cycles because it works very well if you decide to carry a testosterone into a contest.
Effective Dosage:
For men 50 mg - 100 mg every other day or every third day is common. Taking propionate every day is not unheard of. Alot of people use propionate in a precontest cycle. Only serious woman competitors should use propionate at light dosages if at all.
