Peptide Dose 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.

What it does

• Three barrel sizes (0.3 ml, 0.5 ml, 1 ml) with a drawn barrel showing where the plunger lands
• U-100 and U-40 scale switch, because the same volume reads as a different number on each
• Overflow detection: if the dose will not fit the barrel it says so and suggests reconstituting at a larger volume
• Round-number water suggestion, so your usual dose lands on a whole unit mark
• A mg/mcg slip guard that flags a dose larger than the whole vial
• Reference content on the page: reconstitution chart, how to read an insulin syringe, common mistakes, FAQ
• Separate pages for a printable cheat sheet, retatrutide, tirzepatide, and bacteriostatic water shelf life
