How to Use
- Enter the peptide amount in milligrams (mg) - this is the total amount of peptide in your vial
- Enter the volume of bacteriostatic water added in milliliters (ml)
- Enter your desired dose per injection in micrograms (mcg)
- The calculator will automatically display the injection volume in ml, IU, and total number of injections
Calculation Formula
The peptide calculator uses the following formulas:
Concentration (mg/ml) = Peptide amount (mg) ÷ Water volume (ml)
Dose in mg = Desired dose (mcg) ÷ 1000
Injection volume (ml) = Dose (mg) ÷ Concentration (mg/ml)
IU = Injection volume (ml) × 100
Total injections = Peptide amount (mg) ÷ Dose per injection (mg)
Example
Scenario: You have a 5 mg peptide vial and want to inject 250 mcg per dose.
Step 1: Add 2 ml of bacteriostatic water to the 5 mg vial
Step 2: Concentration = 5 mg ÷ 2 ml = 2.5 mg/ml
Step 3: Desired dose = 250 mcg = 0.25 mg
Step 4: Injection volume = 0.25 mg ÷ 2.5 mg/ml = 0.1 ml
Result: Draw 0.1 ml (10 IU) for each injection. You can get 20 total injections from this vial.

Frequently Asked Questions
- How accurate are the peptide calculator results?
- The calculator uses standard mathematical formulas for unit conversions and peptide dosage calculations. Results are accurate based on the input values you provide. Always double-check calculations and consult with a healthcare professional for medical advice.
- What units should I use for peptide calculations?
- Peptide amounts are typically measured in milligrams (mg), water volume in milliliters (ml), and doses in micrograms (mcg). The calculator automatically handles unit conversions between mg and mcg.
- What is IU and how is it calculated?
- IU (International Units) is a standardized measurement. In this calculator, IU is calculated as injection volume in ml multiplied by 100. This provides a standardized way to measure injection volumes.
- Can I use this calculator for any peptide?
- Yes, this calculator works with any peptide as long as you know the peptide amount in mg, the volume of water added in ml, and your desired dose in mcg. The calculations are based on standard unit conversions and are not peptide-specific.
- How do I know how much water to add to my peptide vial?
- The amount of bacteriostatic water you add depends on your desired concentration and injection volume preferences. Common ratios range from 1 ml to 3 ml per 5 mg vial. More water results in a lower concentration and larger injection volumes, while less water creates a higher concentration with smaller injection volumes.
- What if my calculation results in a very small injection volume?
- If your injection volume is very small (less than 0.05 ml), consider adding more bacteriostatic water to increase the volume, making it easier to measure accurately with your syringe. Always ensure you can accurately measure the calculated volume.
