CAS 57-85-2 Androgenic Anabolic Steroids Testosterone Propionate Injection / Oral
What is Testosterone propionate ?
Testosterone Propionate is the shortest estered testosterone preparation available. The added propionate extends the activity of the testosterone but it is still comparatively much faster acting than other testosterone esters such as Cypionate and Enanthate.
For strength and muscle mass gains, Testosterone propionate is quite effective. It is also indicated for Hormone replacement therapy.
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.

Testosterone Propionate dosage and cycle :
Due to Testosterone Propionate possessing a brief active-life of 2-3 days, many athletes involved in tested competitions liked the stuff...a lot. Testing is usually based upon testosterone Epitestosterone levels. Though most individuals have a much lower ratio, athletes can have natural ratios of up to 6:1. This is considered a negative test for steroids¡ usually. By injecting Propionate up to 36 hours before competition, plasma Testosterone levels remained elevated while urine concentrations usually fell within the 6:1 levels. Of course IOC testing protocols would detect any plant origin AAS today. But several groups still simply test for the ratio only.
Testosterone Propionate is considered a fast acting testosterone due to effects beginning in about 1 day. The drug reportedly has all the benefits of other testosterones (quick strength and muscle mass increases, increased training aggressiveness, fast post-training recovery) but caused a distinctly lower level of water retention. Users noted an improved muscle pump and increased appetite after one to two days of administration.
Even with a high rate of aromatization, propionate did not cause gyno as often as other testosterone esters. Users who realize this normally did so due to less frequent injections: Not due to some special quality of the drug. I liked propionate because an increase in IGF-1 was common during liver deactivation. Also because use could be discontinued at the first sign of overt side effects (thus allowing the chemical to no longer be the cause after 2-3 days post-discontinuance).
A high quality muscle gain has been achieved with 50-100mg Testosterone propionate every 1-2 days, 50mg Winstrol Depot every 2nd day, and 20-25mg of Oxandrolone daily. If Parabolan (76mg every other day) was substituted for Winstrol and Proviron is utilized as an anti-estrogen, this became an excellent pre-contest cycle providing superior hardness. Those who had used Primobolan only and no longer made progress at 200-400 mg weekly made consider progress by stacking 200-400mg Primobolan Depot weekly with 50-100mg of Testosterone Propionate every second day.
Improved vascularity was common due to increased in red blood cell count as well. Women who did use testosterones considered propionate to be the superior choice over any other. 25-50mg of Propionate every 5-7 days stacked with any high anabolic such as Anadur, or especially Durabolin caused a dramatic result with less virilizing characteristics. As always, women who are extremely sensitive to androgens reported the use of 1mg Finasteride daily lowered DHT conversion of Propionate.

The Benefits of Testosterone Propionate :
The benefits of Testosterone-Propionate are truly great and in short the benefits most anyone would desire to hold if anabolic steroids were being used. Through the use of Testosterone-Propionate we aptly create a playing field perfect for almost any situation be it bulking, cutting or simply trying to provide an added athletic edge. Through its use the individual can expect to see increases in lean tissue and strength, decreased body fat due to improved metabolic function as well as a greater ability for healing and recovery.
A common misconception is that Testosterone Propionate is only well-suited during a cutting cycle and while it is definitely perfect for a cutting cycle it is perfect because it is testosterone, not because it has the Propionate ester attached. The truth is simple, any testosterone form can be used in a cutting cycle or bulking cycle with equal effectiveness, however, there are variances to consider. As a short ester steroid Testosterone Propionate must be necessarily administered at a minimum of every three days with every other day being far more optimal; because many will be using other short ester steroids during a cutting cycle often it makes sense to use Testosterone-Propionate during this time and simply administer them all at once. However, because peak levels are so easy to control with the use of Testosterone-Propionate due to the short ester being attached many, especially in the competitive bodybuilding world use Testosterone-Propionate in their off-season as well.
