Peptide Stack Calculator

Calculate the per-compound dose for any multi-compound blend or custom stack. Paste a product label to auto-fill, or build your stack manually.

Auto-fill from a product label

Handles most formats — one per line, or separated by |, /, +, commas or semicolons. Dashes and colons between name and amount are fine (GHK-Cu – 65.2 mg), mcg converts automatically, and a missing unit is read as mg. Vial volume is detected when present.
