- The table below compares three standard GHK-Cu formulation approaches used in cosmetic research, with exact calculator inputs for a 5mg peptide vial.
- 0.5% w/v
- 5mg/mL
- 1.0mL
- Broad facial application studies, sensitive skin protocols, wound healing assays
- 28 days at >92% potency
- Best for first-time formulations. Lower copper load reduces oxidation risk and extends working time during application
- 1.0% w/v
- 10mg/mL
- 0.5mL
- Standard anti-aging research formulations, collagen stimulation studies, daily-use protocols
- 28 days at >90% potency
- Industry standard. Balances bioactivity with stability, most published dermatology studies use this concentration
- 2.0% w/v
- 20mg/mL
- 0.25mL
- Targeted photoaging research, intensive treatment protocols, short-duration high-dose studies
- 21 days at >88% potency
- Maximum bioactivity but reduced stability window. Use only when research design requires high copper delivery in minimal volume
- The 1% formulation (10mg/mL) represents the optimal balance between efficacy and shelf life for most cosmetic research applications, which is why it appears most frequently in peer-reviewed trials examining GHK-Cu's effects on collagen synthesis, elastin production, and matrix metalloproteinase inhibition.
