What is Testosterone Propionate?
Testosterone Propionate is a short-ester testosterone with rapid onset and short active duration (~1–3 days). The propionate ester is hydrolysed rapidly post-dissolution, releasing free testosterone for AR activation. Standard short-ester testosterone reference compound for pharmacokinetic studies, androgen receptor pharmacology, and HPG axis research. Research use only.
