What do I mix it with, and where do I draw to?
Put in what your vial says and the dose you want. This works out the volume, the exact mark on the syringe, and shows you where it sits. It does not tell you what dose to take — that number is yours.
The number printed on the label.
Bacteriostatic water you put in.
Per injection, not per week.
Printed on the barrel.
Almost always U-100. Check.
Why this page exists
The most common way people get hurt with injectable peptides is not the compound. It is arithmetic. The FDA has documented people self-administering five to twenty times the amount they intended, and the error that keeps repeating is simple: someone is told to draw five units, and draws fifty. US poison centre calls about this class of drug went from around twelve hundred a year to over eight thousand in 2023, and most were unintentional dosing errors rather than misuse.
That is why the picture is here and not just the number. Fifty units on a U-100 syringe fills half the barrel. Five units is a sliver. A number can be misread by a factor of ten. A picture of where the plunger sits cannot.
Two things this page will not do. It will not choose a dose for you — you bring that number and it converts it. And it will not quote a mix in units without you telling it what is in your vial, because units are meaningless without a concentration: the same "twenty units" is a different amount of peptide in every vial on earth.
