About this site

peptidereconstitution.net is a free calculator for the arithmetic of reconstituting a peptide vial. You enter the amount of peptide printed on the vial, the bacteriostatic water you add and the dose you have been given, and it shows how many units that is on a U-100 insulin syringe, with the math written out.

The calculator only does arithmetic on the numbers you enter. It never suggests a dose, and nothing on this site is medical advice. Many peptides are not approved drugs; talk to a qualified clinician about anything you put in your body.

The Reconstitution Guide

The guide explains the practical side of handling a vial in plain English: mixing and measuring, storage, injection basics and reading a certificate of analysis. Every article lists the sources it is based on, such as peer-reviewed papers, pharmacopeias and manufacturer documentation, so you can check them yourself.
