How it works

Each pouch is dissolved into a stock solution first: 1 g of GHK‑Cu or AHK‑Cu in 20 mL of distilled water (5%), or 1 g of SNAP‑8 in 100 mL (1%). The calculator scales the dose printed on the pouch, per 100 g of finished product, to your batch. Measure small amounts with a ⅛ teaspoon, or count drops: about 20 drops make 1 mL.
