Supports immune response, detoxification, and skin health
The dominant gut phyla, Bacteroidetes and Firmicutes , produce acetate and propionate (mainly Bacteroidetes ) and butyrate (predominantly Firmicutes ) (57)

Common side effects (minimal) Most people: No side effects GHK-Cu extremely well-tolerated Natural peptide (found in body) Minimal adverse effects Possible minor effects: Injection site stinging (common, harmless) Minor bruising at injection sites Slight blue tint to injection site (copper, temporary) Mild headache (rare) Managing side effects: Stinging: Inject slowly, warm peptide to room temp Bruising: Rotate sites, proper technique Blue tint: Normal, fades within days Headache: Hydrate well, reduce dose Contraindications and cautions Avoid if: Pregnancy or breastfeeding (no data) Active cancer (theoretical copper concerns) Wilson's disease (copper metabolism disorder) Hemochromatosis (iron overload, copper caution) Use caution with: Copper supplements (avoid taking both) High copper foods (monitor intake) Liver disease (copper metabolism) Generally safe for: All ages (adults) Men and women Long-term use Most health conditions Copper toxicity concerns Is copper in GHK-Cu dangerous
