ghk-cu tripeptide Copper (GHK-Cu) | Tripeptide Before and after pictures of women who used the ingredients 3% GHK-Cu (Copper Tripeptide-1). Advanced

The peptide combined with LED irradiation (625-635 nm) increased cell viability 12.5-fold, basic fibroblast growth factor production by 230%, and collagen synthesis by 70% compared to LED irradiation alone

Sustained low-level exposure produces more consistent gene expression changes than pulsatile high-concentration delivery

Injectable delivery produces measurable plasma levels and allows the peptide to reach tissues that topical application cannot including deeper wound beds, joint spaces in preclinical models, and scalp follicles below the penetration limit of topical creams

When stacked with GHK-Cu, this duo supercharges recovery, boosts collagen production, enhances skin and improves joint health
