Peptide Calculator for Android
On Android you have two options: this calculator in Chrome, with no install, or the Peptide Library Android app, which includes reconstitution, blend and cycle calculators and saves your calculations alongside schedules and inventory.
Peptide Calculator for Android
The total printed on the vial.
Bacteriostatic water or other diluent, in mL.
The calculator never suggests an amount.
Used to round to the nearest marking you can actually read.
Enter the vial amount, the liquid added and your target amount.
Arithmetic only: it never suggests or assesses an amount. Nothing you type leaves your browser.
Web or app?

|---|---|---|
| Install | None (Add to Home screen optional) | Google Play |
| Account | None | Optional, free |
| Calculators | Reconstitution, concentration, blend, mcg↔mL, mg↔mcg | Single vial, blend, cycle planning |
| Saved calculations | Share link | Saved and synced (some sync features need Pro) |

Both use the same calculation engine, so the same inputs give the same numbers.
