Peptide Dosage Calculator

Calculate your peptide dosage and reconstitution ratios instantly. Our peptide calculator helps determine the correct bacteriostatic water amount, injection volume, and syringe draw (U100 units) for research peptides like BPC-157, CJC-1295, TB-500, and Semaglutide.

How to Use the Peptide Calculator (Step-by-Step Guide)

Follow these simple steps to calculate your peptide dosage, mixing ratio, and injection volume accurately.

Step 1

Select Your Desired Dose

Select the total peptide amount in your vial (e.g., 5mg, 10mg, 15mg)

Choose how you want to calculate your dose:

Dose Per Injection: Enter the amount you want per injection (mcg or mg).
Doses Per Vial: Enter the total number of doses, and the calculator determines the dose per injection.
Help Me Decide: Answer a few questions to get a recommended dose.

If you’re unsure, use the Help Me Decide feature for research-backed peptide dosing guidance.

Choose how you want to calculate your dose:

Dose Per Injection: Enter the amount you want per injection (mcg or mg).
Doses Per Vial: Enter the total number of doses, and the calculator determines the dose per injection.

Select the total peptide amount in your vial (e.g., 5mg, 10mg, 15mg)

Step 2

Enter Bacteriostatic Water Volume

Select how much bacteriostatic water you are adding to reconstitute the peptide (0.5mL – 5mL).

More water = lower concentration. Less water = stronger concentration.

Select how much bacteriostatic water you are adding to reconstitute the peptide (0.5mL – 5mL).

More water = lower concentration. Less water = stronger concentration.

Example: Mixing 5mg of peptide with 2mL of bacteriostatic water creates a concentration of 2.5mg/mL (2500mcg/mL).

Step 2

Review Your Injection Volume & Syringe Draw

Once you’ve entered all details, the calculator will display:

Peptide concentration (mg/mL & mcg/mL)
Injection volume (mL)
Syringe draw (U100 syringe units)
Total doses per vial

Once you’ve entered all details, the calculator will display:

Peptide concentration (mg/mL & mcg/mL)
Injection volume (mL)
Syringe draw (U100 syringe units)
Total doses per vial

Example: If you reconstitute 5mg BPC-157 in 2mL bacteriostatic water and need 250mcg per injection, the calculator will output 0.1mL (10 units on a U100 syringe).
