Enter the vial, the bac water and your dose. It shows how many units to draw, on a mark your syringe really has.

In the app, this math is attached to your real vials. It counts the doses left and tells you before a vial runs out.
Divide the mg in the vial by the mL of bac water. That is the strength. Then divide your dose by the strength and multiply by 100. For example, a 10 mg vial with 2 mL of bac water is 5 mg per mL. A 1 mg dose is 0.2 mL, which is 20 units on a U-100 syringe.
Strength = vial mg ÷ water mL
Units = dose mg ÷ strength × 100
No. Units measure liquid on the syringe, and one unit is 0.01 mL. What a unit holds depends on how you mixed the vial. At 5 mg per mL, 10 units hold 0.5 mg. At 10 mg per mL, the same 10 units hold 1 mg.
The water never changes how much peptide is in the vial. It only changes how many units each dose takes. More water gives a bigger draw that is easier to measure. Less water gives a smaller shot. Many people use 1 or 2 mL, then pick the amount that puts their dose on a clear mark.
All three are U-100 insulin syringes, so one unit is 0.01 mL on each. They hold 100, 50 or 30 units. The two smaller ones have a mark at every unit, and a 1 mL syringe has one every 2 units. So a small dose is easier to read on a smaller syringe.
You can only set the plunger on a mark, so the calculator rounds to the nearest one. On an exact tie it rounds down, so it never tells you to draw more than you asked for. If rounding moves your dose by more than 2%, it says so and suggests an amount of water that puts the dose right on a mark.
Divide the water in the vial by what you draw each time, and round down. With 2 mL of water and 0.1 mL a dose, that is 20 doses. A vial mixed with bac water keeps up to 28 days in the fridge. Mixed with sterile water, it keeps 24 hours. After that, throw out what is left. The storage guide has the rest.
| Mixed with | Keeps in the fridge |
|---|---|
| Bac water | Up to 28 days |
| Sterile water | 24 hours |
Wipe both vial tops with alcohol and let them dry. Let the bac water run slowly down the inside of the glass, then swirl gently until it is clear. Never shake it. The eight-step guide walks through each step.
For a vial you mix, you make it: the mg on the label divided by the mL of bac water you add. A vial that came already mixed prints it, as mg per mL (10 mg/mL) or as a total over a volume (20 mg/2 mL, which is also 10 mg per mL). If the label lists two ingredients, use the number for your medicine, not the added one. For a mixed vial, enter its total mg and total mL above, and go by its label, not this page, for how long it keeps.
Not for a vial you will draw from more than once. Sterile water has no preservative, so a vial mixed with it is for one use within 24 hours. The preservative in bac water is what lets one vial serve many doses. A few peptides are mixed with sterile water on purpose, and the storage guide names them.
1,000 mcg is 1 mg. Vials are usually labelled in mg, and doses are often written in mcg. Mixing them up is a 1,000 times error, so check the unit before every draw. The calculator takes either one.
The count of doses assumes every draw sits exactly on the mark. Drawing one unit past a 10-unit mark each time uses a tenth more, so a vial that holds 20 doses runs out after 18. More water does not add doses either: it spreads the same peptide across more units.
Not on this page. It does one peptide at a time. The Claritide app treats a blend as one vial and works out each part from its certificate of analysis. Go by what the COA says, not the name on the label.
No. This calculator works in mcg and mg. It does not convert IU.
It is free, and there is no account or sign-up. It works in any browser, on a phone or a computer.
No. It does the math on numbers you enter.
