Those who do not mind frequent injections will find propionate to be quite an effective steroid. As with all testosterones, it is a powerful mass drug, capable of producing rapid gains in size and strength. At the same time the buildup of estrogen and DHT (dihydrotestosterone) will be pronounced, so typical testosterone side effects are to be expected.

As with any form of testosterone, Testosterone Propionate, once in the body, is partially converted to both estrogen as well as Dihydrotestosterone. These are often the cause of many side effects such as gynocomastia, water retention, hair loss and prostate enlargement. Also, as with most steroids, injected testosterone propionate will inhibit your natural testosterone levels and HPTA (Hypothalamic Pituitary Testicular Axis). The advantage with testosterone propionate, in this respect, is that it will clear your system more quickly than other versions, and allow you to begin recovery more rapidly.

Also unavoidable with a testosterone are androgenic side effects like oily skin, acne, increased aggression and body/facial hair growth. Those who may have a predisposition for male pattern baldness may also find that propionate will aggravate this condition. To help combat this one may choose to Propecia/Proscar, which will reduce the buildup of DHT in many androgen target tissues. This will help minimize related side effects (particularly hair loss) although it offers us no guarantees. And as with all testosterone products, propionate will also suppress endogenous testosterone production.

Although Propionate, like all other Testosterones, has a high conversion into estrogen, androgenic side effects are less pronounced, probably due to the fact that blood levels do not build up as high. Thus gynecomastia and water retention are lower and users report more muscle hardnes than with other Testosterones. It also has a profound ability to protect your hard earned muscle from the catabolic (muscle wasting) gluco-corticoid hormones and increase red blood cell production, which improves endurance through better oxygenated blood.
