Testosterone propionate, after Testosterone cypionate and enanthate, is the third injectable testosterone ester that needs to be described in detail. This makes sense because, unlike cypionate and enanthate, both of which are widely used and well spread in Europe, propionate is little noticed by most athletes.
The main difference between propionate, cypionate, and enanthate is the respective duration of effect. In contrast to the long-acting enanthate and cypionate depot steroids, propionate has a distinctly lower duration of effect.
Women especially like propionate since, when applied properly, androgenic-caused side effects can be avoided more easily The trick is to increase the time intervals between the various injections so that the testosterone level can fall again and so there is an accumulation of androgens in the female organism. Women therefore take propionate only every 5-7 days and obtain remarkable results with it. The, androgenic effect included in the propionate allows better re-generation without virilization symptoms for hard training women.
