Testosterone propionate gynecomastia

In androgen-responsive target tissues such as the skin, scalp, and prostate, the high relative androgenicity of testosterone is dependant on its reduction to dihydrotestosterone (DHT). The 5-alpha reductase enzyme is responsible for this metabolism of testosterone. The concurrent use of a 5-alpha reductase inhibitor such as finasteride or dutasteride will interfere with site-specific potentiation of testosterone action, lowering the tendency of testosterone drugs to produce androgenic side effects. It is important to remember that both anabolic and androgenic effects are mediated via the cytosolic androgen receptor. Complete separation of testosterone’s anabolic and androgenic properties is not possible, even with total 5-alpha reductase inhibition.

There have been stories the DEA/FDA may frown upon the dispensing of testosterone propionate instead of testosterone cypionate or enanthate by physicians. The reason given: “it is used more often for performance optimization like growth hormone (GH) and is a red flag”. There are numerous physicians prescribing testosterone propionate in their practices without issue. This may warrant further monitoring for any doctor using testosterone propionate. In my book, I recommend 30-50 mg of Testosterone Propionate injected every other day (EOD) as an excellent option for long term TRT administration.

Testosterone esters were synthesized for the first time in 1936, and were found to have greatly improved potency relative to testosterone. [12] Among the esters synthesized, testosterone propionate was the most potent, and for this reason, was selected for further development, subsequently being marketed. [12] Testosterone propionate was introduced in 1937 by Schering AG in Germany under the brand name Testoviron. [8] It was the first ester of testosterone to be introduced, [13] and was the major form of testosterone used medically before 1960. [8] In the 1950s, longer-acting testosterone esters like testosterone enanthate and testosterone cypionate were introduced and superseded testosterone propionate. [13] Although rarely used nowadays due to its short duration, [14] testosterone propionate remains medically available. [8]
