Testosterone Propionate USP
Testosterone propionate USP — the shortest-acting commonly used testosterone ester, in a sterile oil base.
Testaron P delivers Testosterone Propionate USP in a sterile ethyl oleate oil base. Propionate is the shortest-chain ester in common clinical use, resulting in a faster onset of action and shorter duration than longer esters.
This pharmacokinetic profile makes it useful in testosterone replacement protocols where more frequent, smaller dosing intervals are clinically preferred.
Testaron P is manufactured and released against full USP identity, sterility, and assay specifications.
