Evidence-ranked peptides
| Peptide | Use | Evidence |
|---|---|---|
| GHK-Cu GHK-Cu is an investigational peptide, analogue or research construct with evidence ranging from mechanistic studies to limited human trials. | Hair Loss / Hair Improvement insufficient | Human2/5 Animal2/5 Safety2/5 3 verified refs |
| Acetyl Tetrapeptide-3 A topical cosmetic hair peptide studied mainly as part of multi-ingredient products. Combination-trial evidence does not establish peptide-specific hair-growth efficacy. | Hair Loss / Hair Improvement weak | Human2/5 Animal0/5 Safety2/5 1 verified ref |
| Acetyl Hexapeptide-1 A cosmetic peptide marketed for tanning, photoprotection and hair repigmentation through alpha-MSH-related melanogenesis. Independent human evidence is sparse. | Hair Loss / Hair Improvement insufficient | Human2/5 Animal0/5 Safety0/5 1 verified ref |

Current standard management
conventional medicineEvidence-based non-peptide options — including exercise, sleep, nutrition, physiotherapy and licensed medical treatments — often have stronger human evidence than research peptides.
