Peptide Reconstitution Calculator
This peptide reconstitution calculator does the concentration math for a lyophilized vial: enter the peptide amount and the bacteriostatic water you add to get the concentration, draw volume, and the number of units on a U-100 insulin syringe. It is an educational math tool only.

How to Use the Calculator
- Enter the peptide amount in the vial (mg).
- Enter the bacteriostatic water you add (mL).
- Enter the dose you want to draw (mcg).
- Read the concentration, draw volume, and insulin-syringe units.
What the Result Means
This is reconstitution math only — it tells you the concentration of the solution and how many units on a U-100 insulin syringe correspond to a given draw. It is not a dosing recommendation. BPC-157 is not FDA-approved and retatrutide is investigational; consult a licensed clinician.
When to Use This Calculator
- Calculating concentration after reconstitution
- Finding the units on a U-100 insulin syringe
- Understanding bacteriostatic water ratios
Frequently Asked Questions
How do I calculate peptide reconstitution?
Concentration (mg/mL) = peptide amount in the vial ÷ mL of bacteriostatic water added. Draw volume (mL) = desired dose ÷ concentration. Insulin units = draw volume × 100.
How many units is my dose on an insulin syringe?
On a U-100 syringe, 100 units equal 1 mL, so each unit is 0.01 mL. Multiply your draw volume in mL by 100 to get the number of units.
Is this a dosing recommendation?
No. This is a reconstitution math tool only. BPC-157 is not FDA-approved and retatrutide is investigational — always consult a licensed clinician.
