From powder to finished formula
You will need distilled water, a measuring teaspoon, a clean glass jar, and a serum, cream or lotion to use as your base. The same instructions are printed on the card supplied with every order.

≈ 0.12% GHK‑Cu, the standard dose. Add it as the final step, once any heated phase has cooled below 104°F (40°C), and stir until even.

General guidance
- Use distilled water and clean glass or plastic utensils. Metal can react with copper peptides.
- Add actives last, below 104°F (40°C), and stir rather than shake.
- Patch-test each new formulation on a small area of skin for 24 hours before regular use.
- Label every preparation with the active, its strength and the date it was made.
