ghk cu inhibits 5 alpha reductase Is AHK-Cu a DHT Blocker? Copper Pe Steroidal 5α-Reductase: A Therapeutic Target

We asked how mutation/deletion of Cu-binding sites in PrP-OR, PrP-Ala-1, and PrP-Ala-2 affected PrP endocytosis in ATP7B-KO cells

This is the headline finding and it is remarkable

Clinical trial data from Retatrutide research and from comparable GLP-1 compound trials consistently shows that participants maintaining 80g+ of protein daily preserved lean mass significantly better than those whose protein intake dropped under caloric suppression

GHK-Cu addresses the collagen rebuilding pathway directly, works without the irritation risk of retinol (which many midlife women can no longer tolerate), and has anti-inflammatory properties that benefit reactive, sensitised skin during hormonal transition

That makes it well-suited to skin and general remodeling goals, but it delivers less TB-500 per dose than a standalone injury protocol
