ghk-cu 5-alpha reductase inhibition Copper tripeptide (GHK-Cu) | Tripeptide AHK-Cu vs Finasteride for Hair

Patients in their late 30s to early 50s who have begun noticing collagen loss but have not yet developed deep structural atrophy represent the sweet spot

While it may indirectly support overall skin health through its role in glutathione synthesis, it is not typically used as a standalone ingredient specifically for pigmentation concerns

Further work is required to elucidate the significance of DHAR activity and to clarify discrepancies between modelled and experimental data
