Interactive calculator on the page: reconstitution, blend. It runs in the browser and never suggests an amount.

## Web or app?

|  | This site in Chrome | Peptide Library Android 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) |
| Tracking, reminders, inventory | No | Yes |

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