  • Topical 0.5–2% GHK-Cu serum (liposomal)
  • 3–5 days
  • 10–14 days
  • 8–10 weeks
  • Requires twice-daily application; pH sensitivity; degrades in light
  • Best for superficial wounds and cosmetic use. Proven penetration, minimal risk
  • Hydrogel patch with GHK-Cu (1–3mg/patch)
  • 24–72 hours
  • 7–10 days
  • 6–8 weeks
  • Single-use cost; occlusion contraindicated in infected wounds
  • Ideal for post-surgical wounds. Sustained release, no compliance burden
  • Subcutaneous injection (0.5–1mg/site)
  • 24–48 hours
  • 5–7 days
  • Requires medical administration; injection site reactions possible
  • Fastest timeline for deep wounds. Direct bioavailability, professional oversight required
  • Generic 'copper peptide' cream (unspecified peptide)
  • Variable or absent
  • Minimal documented effect
  • Not applicable
  • Unknown peptide identity; no HPLC verification; pH often incompatible
  • High risk of inactive formulation. Copper alone without GHK tripeptide lacks mechanism
