What is Testosterone Propionate?
Testosterone Propionate (Short-acting esterified testosterone (injectable)) is a testosterone propionate ester — C₂₂H₃₂O₃, MW 344.5. Shortest-chain testosterone ester providing rapid onset (peak ~24–36h, active ~2–3 days). Requires more frequent administration than longer esters. Free testosterone activates the androgen receptor (AR). Aromatases to oestradiol via CYP19A1.
