Testosterone esters were synthesized for the first time in 1936, and were found to have greatly improved potency relative to testosterone.  Among the esters synthesized, testosterone propionate was the most potent, and for this reason, was selected for further development, subsequently being marketed.  Testosterone propionate was introduced in 1937 by Schering AG in Germany under the brand name Testoviron.  It was the first ester of testosterone to be introduced,  and was the major form of testosterone used medically before 1960.  In the 1950s, longer-acting testosterone esters like testosterone enanthate and testosterone cypionate were introduced and superseded testosterone propionate.  Although rarely used nowadays due to its short duration,  testosterone propionate remains medically available. 
According to the manufacturer's data, the steroid Testosterone Propionate has a very specific androgenic effect, namely, it stimulates the development and functionality of the external genitalia, affects the prostate gland, and also has a direct effect on secondary gender characteristics in men. In particular, on the timbre of voice and hair growth. In particular, Testosterone Propionate, the price of which is available to everyone in our store, affects the process of body structure formation, the processes of spermatogenesis, and also increases the level of libido.
Testosterone Propionate also converts to both Estrogen (through Aromatization) and Dihydrotestosterone (through 5a-reduction). Most of the side effects people experience with testosterone use is actually from it’s conversion to these two substrates. Thus, hair loss , water retention, acne, and other side effects are possible with use of this drug. Conversion to these hormones is also responsible for some of testosterone’s ability to build muscle; therefore when many side effects are avoided with the use of ancillary compounds, some of the muscle building properties are also stunted.
