About this tool

Peptide Dose Tool answers one question precisely: what mark do you draw to on the syringe? Enter the peptide in the vial (mg or mcg), the bacteriostatic water you added (ml or syringe units) and the dose you want (mcg or mg). It returns the exact unit count to draw to, the concentration in mg/ml, the injection volume in ml, how many doses the vial holds, and cost per dose if you enter what the vial cost. A drawing of the barrel shows where the plunger lands. Switch between 0.3 ml, 0.5 ml and 1 ml barrels and between the U-100 and U-40 scales, which turn the same volume into a different number. If a dose overflows the barrel it says so and suggests reconstituting at a larger volume, and it can suggest the water volume that puts your usual dose on a round, easy to read mark. Around the calculator sit a reconstitution chart, a printable cheat sheet, compound pages for retatrutide and tirzepatide, and a bacteriostatic water shelf life guide.
