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.
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.
Example: Mixing 5mg of peptide with 2mL of bacteriostatic water creates a concentration of 2.5mg/mL (2500mcg/mL).
Step 3: 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
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).
