best time to inject ghk-cu morning or evening Peptides Before and After: Dosage, Benefits & How It Works for Skin and Hair GHK-CU Peptide Dosage Chart: Complete

They added GHK-Cu in concentrations of 10 M to 10 M and measured: Collagen synthesis (by radioactive proline incorporation) Non-collagen protein synthesis Cell proliferation What they found: Stimulation of collagen synthesis by 70 % at the optimal concentration of 10 M (1 nM) The effect was NOT dependent on increased proliferation, fibroblasts increased production per cell Background: GHK without copper had a dramatically weaker effect , Cu is critical Reversibility: After removing GHK-Cu, synthesis returned to baseline Why it matters: This is the fundamental mechanistic study that documented the effect of GHK-Cu on collagen
