Testosterone propionate is similar to enanthate, cypionate, and sustanon. However, compared to enanthate or cypionate, propionate is a much shorter ester and will release more quickly into the bloodstream. As a result of its short action, more frequent (daily) injections are required to prevent steroid blood levels from tapering down and becoming ineffective. An injection schedule of every third day is about the longest you would want to perform using propionate to achieve good results. For best results - daily injections are more suitable given the nature of this agent. Peak propionate levels take place after 24-36 hours and taper down from there. As a result of the frequency of injections required of propionate, it is not a very attractive steroid for those who are doing their first cycle or those who do not like intra-muscular injections to begin with. For a first cycle, a longer acting, single ester testosterone such as enanthate or cypionate or preferred because in both cases few injections can be made while maintaining stable blood levels and thereby optimizing results. Respectively, enanthate should be injected twice weekly and cypionate once weekly. Since both yield similar results, the first time user would more likely enjoy either of those two compounds over propionate. The benefits of propionate may not be worth the additional energy required for the injections. Propionate is also a relatively painful steroid to inject with uses complaining that the same spots become aggravated with additional injections which require injecting in several different places for prevention of this pain. The injection site may become irritated and users have complained of long lasting pain caused by the injections. For these reasons, propionate is not such a good idea for the first time steroid user, however, enanthate and cypionate are not without their share of complications and all factors should be assessed before beginning with any steroid cycle. If propionate is the steroid of choice, ancillary drugs such as nolvadex, proviron and arimidex are advised to have on hand during the cycle in case symptoms of gyno arise (or if you wish, you can run these drugs during the cycle for prevention). All testosterones will aromatize, although some have a lesser chance of it. Propionate may be one of those drugs, but proper precautions should be taken, nevertheless.
Testosterone propionate has a short active life of 2-3 days. It has a short half life and is active in the system only a day after injection. Propionate is one of the componenets of the four testosterone ester blend sustanon, and, along with phenylpropionate, is the reason why more frequent injections are required with sustanon (to take full advantage of all esters in the blend). Propionate has the same benefits of every other testosterone along with the advantage of being fast acting. Another advantage of propionate when compared to other steroids is that the level of water retention and water based gains on cycle are lower when compared to counterparts such as testosterone enanthate or testosterone cypionate. The benefits of testosterone, such as improved muscle pumps can be seen very soon after propionate is administered due to its short half life and related length of activation.
Propionate does have a high rate of aromatization, similar to any other testosterone, and as a result, ancillary drugs such as nolvadex or its weaker counterpart clomid should be kept on hand during a cycle where propionate is included to stop gyno from occurring.
