GHK-Cu

A copper-binding tripeptide investigated mainly in laboratory, wound and topical cosmetic contexts. Evidence does not establish an injectable human regimen.

Evidence context, not a personal protocol

Quantities below reproduce study or label context. They do not assess suitability, product equivalence or individual risk.

Regimens studied

Published laboratory, wound-healing and cosmetic research populations

Formulations and exposure varied substantially across the cited literature

No evidence-backed injectable schedule is presented because the reviewed literature does not establish one.

Evidence summary

GHK-Cu is discussed across cell, animal, wound and cosmetic research. Route and formulation matter, and topical findings cannot be converted into an injection protocol.

Protocol status

RetaCalc deliberately withholds an injectable studied-regimen table until suitable controlled human evidence supports one.

Warnings and contraindications

Topical or laboratory findings do not establish safety for injection.
Copper exposure and product-specific formulation require separate assessment.
