Peptly: Peptide Calculator

Peptly is a peptide reconstitution calculator that replaces guesswork with one clear number.

Enter the vial strength, the volume of bacteriostatic water you are adding and the dose you want, and Peptly shows exactly how many units to draw — rendered on a visual syringe so you can check it against the barrel in your hand before you draw. It handles U-100 and other syringe types, mcg and mg magnitudes, and multi-peptide blends.

Beyond the calculator: log every injection with site and date, save your reconstitutions and reload them in one tap, keep dosing schedules with reminders, and browse 23 research peptide profiles with typical reconstitution notes.

Peptly runs on-device and needs no account. Your log stays on your phone.

Peptly is a calculation and record-keeping tool. It is not medical advice and does not prescribe, recommend or supply anything.
