Peptide calculator
Works out reconstitution: how much water to add, the resulting concentration and which mark to fill the syringe to for your dose. Pick a peptide from the catalog — vial content and preset doses fill in automatically — or enter your own values.
How to use the calculator
Choose the syringe you will use: U-100 of 1, 0.5 or 0.3 ml, or U-40. The number of units depends on it.
Find a peptide from the catalog — the vial content fills in. Or tap 2, 5, 10 mg or enter your own.
Enter how much bacteriostatic water you add. Catalog peptides come with a suggestion.
Pick a preset dose or enter your own in mcg or mg.
The calculator shows the syringe mark, volume per dose, concentration and doses per vial.
About the calculation
How is the syringe mark calculated?
Vial amount divided by water volume gives the concentration. Dose divided by concentration gives the volume per dose in ml. A U-100 syringe has 100 units per ml, U-40 has 40: 0.1 ml is 10 units on U-100 or 4 units on U-40.
How much water should I add?
Less water means higher concentration and a smaller volume per dose. More water makes small doses easier to measure. Catalog peptides come with a suggested volume; any value can be entered.
What is the difference between U-100 and U-40?
The size of one unit. U-100 splits 1 ml into 100 units, U-40 into 40, so the same volume takes fewer units on U-40. Choose the syringe you will actually use.
Can I enter my own values?
Yes: vial amount, water and dose can all be typed in — the result updates instantly.
How do I calculate a pen?
Pick a pen from the catalog: the cartridge volume fills in and the calculator shows how many units to dial. 1 unit is 0.01 ml.
