Peptulator

Peptulator is a free reconstitution and dosing calculator for peptides. Enter what is on the vial, how much bacteriostatic water you added and the dose, and it returns the concentration, the volume to draw in mL and the exact mark on an insulin syringe. It also runs backwards, from units drawn to dose.

It covers 27 compounds with presets, handles U-100 and U-40 syringes, and every formula is written out on the page and on a methodology page, so any answer can be checked by hand.

No account, no ads, no vendor links. Published by the team behind Peptide Bureau. It converts units and volumes only: research use, not medical advice.
