Finasteride is a pharmaceutical that finasteride's mechanism is mechanistically straightforward but systemically consequential: it is a potent, selective, irreversible inhibitor of 5α-reductase type ii (and, to a…. AHK-Cu is a skin & hair that ahk-cu delivers bioavailable copper ions to follicular and dermal tissues. copper acts as a cofactor for lysyl oxidase (collagen/elastin crosslinking), superoxide dismutase…. The two differ in mechanism, half-life (not reported vs Unknown (topical half-life, follicular retention not well characterized)), and typical dose range. ### Which has the longer half-life, Finasteride or AHK-Cu? Finasteride has a half-life of not reported. AHK-Cu has a half-life of Unknown (topical half-life, follicular retention not well characterized). Longer half-lives generally mean less frequent dosing but slower on/off kinetics. ### Which is cheaper, Finasteride or AHK-Cu? Lowest listed price on BodyHackGuide: Finasteride from $39.99, AHK-Cu from $44.99. Prices are pulled from the vendor listings tracked on BHG and change frequently.
