What this record can say

Evidence snapshot

A 2026 ClinicalTrials.gov record describes a recruiting topical wound-healing study, but has no posted results. A planned topical wound study is not evidence for hair, cosmetic appearance, injectable products, or efficacy.

Safety context

Read uncertainty as information

FDA's table addresses injectable GHK-Cu specifically and notes potential immunogenicity related to peptide aggregation plus limited human data for safety considerations.

Tested sport

Anti-doping context

No simplified clearance label is shown. Tested athletes should verify the current List with their anti-doping organisation before relying on any status.

Regulatory scope

Context is not a universal answer

United States: this reflects FDA's discussion of injectable compounded GHK-Cu, not every formulation or a global legal determination.

Study-level evidence

What the individual records actually say.

Every row preserves identity and context. A related molecule, a tissue experiment, or a trial registration cannot become proof for the community claim.
