We cant stress this enough

GHK-Cu and Antioxidative potential A study has investigated the possible mechanisms through which the peptide complex GHK-Cu could influence anti-inflammatory actions, particularly against lung tissue inflammation induced by cigarette smoke (CS)

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

The mechanistic contrast between these two ingredients is the single most important thing to understand, because it predicts almost everything about their benefits and side effects

Once your skin is used to it, you can always move up to a higher percentage if you feel your specific cosmetic goals call for it
