Peptide Dosage Calculator
Convert Mcg to Syringe Volumes
Convert mg and mcg into syringe volumes and unit markings for vial-based peptide products.
How To Use This Calculator
This calculator converts a known dose and concentration into a draw volume. It does not decide whether a dose is appropriate for you.
Always confirm the vial concentration first, then use the calculator to translate that concentration into milliliters or syringe marks.
If the vial label or prescription instructions differ from the calculator input, follow the label and not the calculator.
Simple Math Workflow
How To Read The Result
The output is only a conversion result. If your concentration changes, the draw volume changes too.
If the result is very small, check your syringe markings carefully. Small volumes are easy to misread.
Use the calculator alongside a written dose log so you can verify the math later if needed.
Safety Notes
Do not use this page as a substitute for the product label, the pharmacy instructions, or your prescriber's directions.
If you are unsure which syringe format you have, check the barrel before drawing anything.
A quick second check is better than guessing when the dose is measured in a tiny volume.
Frequently Asked Questions
Enter a dose and a concentration, and the calculator converts that into a draw volume.
Yes. All Shotlee calculators are free to use with no registration required.
The math is exact if the concentration you enter is correct, but the calculator does not tell you whether the dose is medically appropriate.
Recalculate any time the vial concentration, dose, or syringe type changes.
