What is Testosterone Propionate
Testosterone propionate like Testosterone Cypionate and enanthate is a widely used steroid by many bodybuilders. The major difference between testosterone propionate and other formulations is the onset and duration of response.
In essence, testosterone is much faster acting and is released from the injected site within 3-4 days. Once absorbed into the blood stream it remains for 24-48 hours. This shorter duration of action compared to the other testosterone formulations also results in lesser side effects.
