Peptide Dose Calculator

Reconstitution and U-100 syringe dosing, with a clear guide to mcg, mg and syringe units. Educational tool, not medical advice.

Peptide Dose Calculator turns three numbers into the one you actually need: the exact mark to draw on your syringe. Enter the amount of peptide in the vial, the amount of bacteriostatic water you added, and your target dose. The calculator returns the volume to draw — shown both in milliliters and in units on a U-100 insulin syringe — along with the resulting concentration so you can check the math yourself. WHAT MAKES THIS ONE DIFFERENT Most dose calculators give you a number with no context. This one explains the units, which is where nearly every dosing error starts. - Plain-English guide to mcg, mg, and syringe units — including why "IU" is a misnomer for the marks on an insulin syringe, and why weight and volume only connect through concentration. - A visual U-100 syringe that fills to your calculated draw, so the number on screen matches the barrel in your hand. - Reference table of commonly cited dosing figures for several peptides. - Automatic warnings when a dose exceeds one full syringe, or when it is too small to measure accurately. - Switch between mg and mcg for the dose input.
