Testosterone propionate was the first androgenic steroid to be synthesized. Over the decades of testosterone propionate usage, bodybuilders have found out that the propionate is really an effective way of gaining body mass and maintaining the body muscles during the cutting period. Testosterone propionate is commonly referred to as ‘prop’ or ‘test prop’ among steroid enthusiasts. The propionate is actually a testosterone ester that is injected to the muscle cells in the form of an injectable suspension. Testosterone, when injected from outside, has to be injected in its ester forms like testosterone propionate or testosterone cypionate. The presence of ester determines the amount of testosterone in 100 mgs of the suspension. For instance, Testosterone cypionate introduces 69.90 mgs of testosterone per 100 mg of the suspension. Testosterone propionate introduces 83.72 mgs of testosterone per 100 mg of the suspension.
Testosterone Propionate is the shortest estered testosterone preparation available on the market currently. It seems to promote less water retention than longer estered versions of the product.
Testosterone is the hormone which served as the base molecule for all anabolic steroids currently on the market today. By adding or subtracting from it, all steroids we see currently in circulation, were developed. It is both a highly anabolic and highly androgenic hormone, having an anabolic (muscle building) as well as anabolic rating of 100 each, respectively. Testosterone exerts the majority of its effects by initiating gene transcription in a very specific manner, thereby promoting increased nitrogen retention in the muscle. Testosterone is also known to increases levels of the growth factor IGF-1 in both the muscle tissue as well as the liver. Testosterone also increases the activity of satellite cells, which are cells that play an active role in repairing exercise-damaged muscle.
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.
Typically, testosterone propionate is stacked with other quick acting injectables, and is usually reserved for cutting cycles, where short esters are preferred. Trenbolone Acetate and Masteron are typically used in such cycles.
