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 dosage 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 do I determine the correct peptide dosage?
- Peptide dosages vary depending on the specific peptide and your goals. Common dosages range from 100-500 mcg per injection. Always consult with a healthcare professional or refer to research literature for recommended dosages for your specific peptide.
- What is the difference between mg and mcg in peptide dosing?
- Milligrams (mg) and micrograms (mcg) are units of mass. 1 mg equals 1000 mcg. Peptide amounts are typically measured in mg (vial size), while individual doses are often measured in mcg. The calculator automatically converts between these units.
- How often should I inject peptides?
- Injection frequency depends on the specific peptide and your protocol. Some peptides are injected daily, while others may be injected every other day or weekly. Always follow the recommended protocol for your specific peptide and consult with a healthcare professional.
- Can I adjust the water volume to change the injection volume?
- Yes, adjusting the water volume will change both the concentration and injection volume. More water results in a lower concentration and larger injection volumes, while less water creates a higher concentration with smaller injection volumes. Choose a volume that makes accurate measurement easy.
- What does "total injections" mean in the results?
- "Total injections" shows how many injections you can get from your peptide vial based on your desired dose per injection. This helps you plan your peptide cycle and understand how long your vial will last.
- Is it safe to use bacteriostatic water for reconstitution?
- Bacteriostatic water is commonly used for reconstituting peptides as it contains a preservative (benzyl alcohol) that prevents bacterial growth. However, always use sterile, pharmaceutical-grade bacteriostatic water and follow proper aseptic techniques when reconstituting peptides.
