mechanism of action ghk-cu copper peptide hair growth Guide: Protocols & Results for Canadians GHK-Cu (Copper Peptide) Deep Dive:

Oral bioavailability is estimated at approximately 38%

Studies in surgical wounds showed that topical GHK-Cu application reduced healing time, improved cosmetic outcomes, and decreased scar formation

I find the chronic injury situation illustrates an important principle: peptides accelerate natural healing but cannot force tissue to repair that has fundamentally changed over years of dysfunction

This decline may partly explain why wound healing and skin regeneration slow in older adults [4]

The practical takeaway: Injection = high systemic distribution tendons, ligaments, muscle, joints, vascular tissue Oral = high local GI concentration intestinal lining, gastric mucosa, gut repair Nasal = intermediate systemic delivery potential neurological targeting, emerging evidence only Injectable BPC-157: Highest Bioavailability for Systemic and Musculoskeletal Goals Injectable BPC-157 is the best-studied delivery method for healing applications outside the gastrointestinal tract
