Testosterone palmitate, or testosterone hexadecanoate, also known as testosterone 17β-palmitate, as well as androst-4-en-17β-ol-3-one 17β-palmitate, is an anabolic-androgenic steroid (AAS) and an androgen ester – specifically, the C17β palmitate (hexadecanoate) ester of testosterone – which was never marketed.[1][2][3] It is a prodrug of testosterone and, when administered via intramuscular injection, is associated with a long-lasting depot effect and extended duration of action.[1]
Testosterone palmitate is a longer-chain ester of testosterone compared to testosterone undecanoate.[1] Relative to testosterone undecanoate, testosterone palmitate shows higher oral bioavailability.[1] However, no free testosterone was observed after administration of testosterone palmitate, suggesting that it is not hydrolyzed as well.[1] On the other hand, another study found that testosterone palmitate was hydrolyzed in humans.[4]
