How it works

A naturally occurring copper-binding tripeptide that declines significantly with age. Promotes collagen and elastin synthesis, wound healing, stem cell proliferation, anti-inflammatory activity, and antioxidant enzyme expression. Bryan Johnson uses it topically in his Blueprint peptide serum; injectable GHK-Cu achieves systemic effects.

Research summary

Well-studied in wound healing and cosmetic dermatology — over 50 published studies. Strong evidence for topical use in skin repair and hair growth, most visibly used in Bryan Johnson's Blueprint peptide serum. Injectable form extrapolates systemic regenerative benefits from tissue-specific data.

How this connects to your protocol

Higher protein intake in adults over 35 is the strongest dietary intervention against sarcopenia (age-related muscle loss). GH peptide protocols amplify the benefit — but only if protein substrate is available.

Targets are evidence-based estimates. Consult your practitioner for personalised advice.

Risks & side effects

Copper accumulation at very high doses
Skin irritation (topical form)
Limited injectable human safety data
