That's the one question PeptOnyx Calculator answers. You've already got a prescribed dose -- this isn't a dosing advisor and it doesn't recommend protocols. It takes the vial amount, how much you reconstituted it with, and the dose you've been prescribed, and shows you exactly what that translates to on a syringe: the volume in mL and the exact unit mark to draw to.
Show the calculation, don't just trust it
Every result comes with the full working shown underneath -- concentration, volume, and syringe units, step by step -- so you can check the maths yourself instead of taking a black box's word for it. If something about your numbers looks off (a dose bigger than what's left in the vial, a measurement that lands between graduation marks), PeptOnyx tells you before you draw, not after.
