Short Active Life
It acts much faster than other testosterone esters such as cypionate or enanthate, and requires a much more frequent dosing schedule, in order to maintain stable blood levels. The main function of Testosterone propionate is to promote metabolism. Anabolic effects include growth of muscle mass and strength, enhancement of bone density and strength, and stimulation of linear growth and bone maturation.
Testosterone Propionate is the shortest commonly ester attached to the Testosterone hormone. This means it takes your body the least amount of time to rid itself of the ester and release the parent hormone into the body. Due to its short active life, testosterone propionate typically needs to be injected every other day at a minimum. Anecdotally, testosterone propionate causes the least side effects and the least bloating; these side effects usually subside very quickly when use is ceased.
The major disadvantage of the short active life is that users will have to inject Test Prop at least every other day throughout its cycle to get proper results. The advantages, however, are less bloating and water retention that longer-estered products and because there is less ester in each vial, there is more actual testosterone per injection, which brings better results.
Testosterone propionate is a commonly manufactured, oil-based injectable testosterone compound. The propionate ester will slow the rate in which the steroid is released from the injection site, but only for a few days. Testosterone propionate is therefore much faster acting than other testosterone esters such as cypionate or enanthate, and requires a much more frequent dosing schedule, in order to maintain stable blood levels. While cypionate and enanthate are injected on a weekly or bi-weekly basis, propionate is usually injected every second. The propionate ester can be very irritating to the site of injection. In fact, many sensitive individuals choose to stay away from this steroid completely, their body reacting with a pronounced soreness and low-grade fever that may last for a few days.
Testosterone Propionate Dosage
The most common dosage schedule for this compound (men) is to inject 50 to 100mg, every day or 2nd day. As with the more popular esters, the total weekly dosage would be in the range of 300-700mg. As with all testosterone compounds, this drug is most appropriately suited for bulking phases of training. Here it is most often combined with other strong agents such as Dianabol, Anadrol, or Deca-Durabolin, combinations that prove to work quite well. Propionate however is sometimes also used with nonaromatizing anabolics/androgens during cutting or dieting phases of training, a time when it’s fast action and androgenic nature are also appreciated. Popular stacks include a moderate dosage of propionate with an oral anabolic like Winstrol (15-35 mg daily), Primobolan (50-150mg daily) or oxandrolone (15-30mg daily). Provided the body fat percentage is sufficiently low, the look of dense muscularity can be notably improved (barring any excess estrogen buildup from the testosterone). One could also add a non-aromatizing androgen like trenbolone or Halotestin, which should have an even more extreme effect on subcutaneous body fat and muscle hardness. Of course with the added androgen content any related side effects will become much more pronounced.
