ghk-cu naturally occurring in human plasma levels decline with age REPAIR being the clue!!! What if aging skin isn't just about “losing collagen”… but losing the body's ability to communicate repair? ✨ Meet GHK- Cu — the copper tripeptide quietly becoming one of GHK-Cu - Peptide for Collagen,
Description
,

The thinking is that by concentrating the peptide in the inflamed or damaged areabe it the lower back near the compressed nerve root or the gluteal area for piriformis syndromeyou maximize its local effects before it enters systemic circulation

Tripeptide-Copper Complex GHK-Cu Stimulates Collagen Production and Elastin Repair in Cultured Human Dermal Fibroblasts
We present data on the molecular mechanisms underlying hair growth stimulation, including activation of the Wnt/-catenin, AKT, and MAPK/CREB signaling pathways and induction of growth factors

If it lasts more than a week or is severe, inform your doctor
