Myth: A higher milligram count on a supplement label always means better results
Human research on GHK-Cu is most meaningful in topical skin and wound-healing contexts, with fewer data for injectable use, systemic anti-aging, or hair-loss treatment [2], [3], [7], [8]
In addition, Bissinger et al
No wheat, gluten, soybeans, dairy, egg, fish/shellfish, peanuts/tree nuts or sesame
Toxic solvent residues DMF (dimethylformamide) Known liver toxin Associated with reproductive toxicity Must be removed to extremely low limits in GMP drugs DCM (dichloromethane / methylene chloride) Probable human carcinogen Central nervous system depressant Dangerous even in small amounts if injected TFA (trifluoroacetic acid) Corrosive Can remain in peptides as unmeasured TFA salt Pharmaceutical products often convert TFA salts to safer counterions Without validated HPLC, mass spectrometry, and residual solvent testing, patients may be injected with harmful chemical contaminants
GHK-Cu is one of the very few skincare ingredients where the before-and-after story is backed by genuine science rather than clever photography
