- 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
