RESEARCH SNAPSHOT
Research-associated effects
Areas of effect or outcome that researchers have investigated or reported in the literature. These are research associations, not guarantees of a particular result.
Evidence varies by compound, model, formulation, route, endpoint, and study design. Component-level findings do not automatically establish the same effect for a blend.
RESEARCH NOTE
Topical evidence is not systemic evidence
A topical formulation and an injectable formulation are not interchangeable experiments. Findings about skin or local application should not be used as proof of effects from systemic exposure.
RESEARCH NOTE
What the regulator says
FDA has identified limited human safety data for injectable GHK-Cu and notes potential concerns involving immunogenicity, aggregation, peps-related impurities, and characterization.
RESEARCH NOTE
A better research question
Instead of asking “Does GHK-Cu work?”, specify the model, route, endpoint, and population. That turns a vague claim into a question that can actually be evaluated.
