What is a peptide calculator?
A peptide calculator is a math tool that converts vial quantity, added liquid volume, and a selected calculation amount into concentration and volume results. It helps people understand the relationship between milligrams, micrograms, milliliters, and U-100 syringe unit markings without offering medical directions.
PeptideCalculator.website is designed as an educational reference. It does not sell peptides, recommend use, describe treatment plans, or claim health outcomes.
How to use the peptide calculator
The calculator converts the vial amount from mg to mcg, divides that amount by the water added, then divides the selected amount by the concentration. The resulting mL value is converted to U-100 units by multiplying by 100.
These calculations are useful for learning arithmetic after reconstitution, but they do not establish whether a product, amount, route, or schedule is appropriate.
Understanding mg, mcg, mL and units
Milligrams and micrograms measure mass. Milliliters measure liquid volume. U-100 syringe units are markings based on a syringe scale where 100 units equal 1 mL.
Keeping those categories separate is important because many calculation errors happen when mass, volume, and syringe markings are mixed together.

Common calculation examples
| Vial amount | Water added | Concentration | Selected amount | mL result | U-100 units |
|---|---|---|---|---|---|
| 5 mg | 1 mL | 5000 mcg/mL | 250 mcg | 0.05 mL | 5 units |
| 5 mg | 2 mL | 2500 mcg/mL | 250 mcg | 0.1 mL | 10 units |
| 10 mg | 2 mL | 5000 mcg/mL | 500 mcg | 0.1 mL | 10 units |
| 10 mg | 3 mL | 3333 mcg/mL | 500 mcg | 0.15 mL | 15 units |
| 15 mg | 3 mL | 5000 mcg/mL | 1000 mcg | 0.2 mL | 20 units |
Frequently asked questions
Does this calculator recommend a peptide dose?
No. It only performs unit conversion and reconstitution math for a selected calculation amount. It does not provide medical advice, prescriptions, dosing schedules, or safety guidance.
What does U-100 mean?
U-100 means 100 insulin syringe units equal 1 mL. The calculator converts the selected mL result into U-100 markings by multiplying mL by 100.
Can this replace advice from a clinician or pharmacist?
No. Any medication, injectable product, or research material can involve risks that math alone cannot evaluate. Consult a licensed healthcare professional or pharmacist.
