About Peptide Dose Calculator
Peptide Dose Calculator turns a dose you already have into the units to draw on a U-100 insulin syringe, and back. It shows every step of the math so you can check it.

Why it exists
This site has no products, affiliate links or sponsored placements. Its main tools convert a dose and concentration into a volume. Separate reference pages explain product labels and how to check the numbers.
What it does
- Works out the concentration from the amount in a vial and the volume of liquid it holds
- Converts a dose in mcg or mg into mL and U-100 syringe units, or units back into a dose
- Checks the draw fits the syringe you have, shows the nearest lines, and flags impossible numbers
- Handles two-compound blends, keeping each component's amount separate
- Shows the solution volume for a concentration you've chosen
What it doesn't do
- It doesn't recommend an individual dose, dilution or schedule. Those depend on the product, the person and the prescriber. Separate schedule pages describe information in specified product labels.
- It doesn't tell you how to prepare, store or inject anything.
- It can't verify what's in a vial. A correct calculation on an unverified product is still an unverified product.
Several compounds named on this site, such as retatrutide, BPC-157 and TB-500, are investigational or not approved for human use. Pages say so where it matters.
How the numbers are checked
Every formula lives in one place and is covered by automated tests with hand-worked reference values, round trips and edge cases. Every number in the site's tables is recalculated by those tests before each release. Dr. J Fisher, a pharmacist with 15 years of practice in Florida, has also reviewed the calculators for quality and accuracy. See the editorial policy for the rest.
Found a mistake?
A wrong number on a dosing page matters more than most errors. If you find one, please report it to ezra@peptidedosecalculator.org, with the page and the numbers you entered.
