Testosterone Propionate is one of the oldest anabolic steroids around, branded under many various names by schering, the company introduced testosterone propionate under the brand name testoviron propionate, which became the first injectible androgen avaliable for prescription in the U.S.
Testosterone Propionate was also avaliable orally by a company called buccal.
Compared to other esterfied preperations like Testosterone Enanthate and cypionate, propionate is relatively fast acting, needing to be injected every 2-3 days to keep up blood plasma concentrations and to maximise gains. Testosterone Propionate will produce massive gains in both size and strength increasing LBM (Lean Body Mass), nitrogen retention and protein synthesis. Some users prefer other testosterone compounds like Sustanon 250 due to the frequent and often painfully administered injections that need to be taken so often.
Bodybuilders are keen to take Testosterone Propionate during dieting or cutting phases of training due to the hardness that it gives to the physique, with notably less water retention gained when compared to other esters such as testosterone enanthate and testosterone cypionate.
The oral compounds are much better than injectable preperations, and all underground laboratory forms of testosterone Propionate cause irritation to the tissues when injected, where as pharmaceutical forms of Testosterone Propionate such as Viromone are less painful.
