Enter how many milligrams are in your vial and how much bacteriostatic water you're adding. You'll get the concentration straight away, plus the mark to draw to on a standard 100-unit insulin syringe. It's just arithmetic on your own numbers — nothing is recommended.
Pure arithmetic on the numbers you type — nothing is recommended, stored, or sent anywhere. Always follow the instructions supplied with your own vial.
Two numbers decide everything: how much peptide is in the vial, and how much water you add.
Not weaker overall — the vial still holds the same total peptide. More water just spreads it across more volume, so each unit on the syringe carries less. Many people add a bit more water on purpose because larger marks are easier to read and measure accurately. Less water means fewer units for the same amount, which can be fiddly.
The maths is exact, but the real world isn't: a little liquid always clings to the vial and needle, and syringe markings have their own tolerance. This tool shows the ideal figures for the numbers you enter — it doesn't tell you what to take, and it isn't a substitute for the instructions that came with your product.
Peptide Wizard stores each vial you reconstitute — the mg, the water, the concentration and the date you mixed it — so the units are always there when you need them and you're never redoing the sum. It also tracks cost per dose, warns you before a mixed vial expires, and reminds you when a dose is due.
