📌 Peptide Dosage Calculator for Reconstitution and Syringe Units
This peptide dosage calculator helps estimate how much liquid to draw after reconstituting a peptide vial with bacteriostatic water. It calculates the final concentration, injection volume, and U-100 insulin syringe units based on your selected vial strength, water volume, and target dose.
The calculator can be used for common peptide vial strengths such as 5mg, 10mg, 15mg, 20mg, 30mg, and 40mg. It also supports custom vial strengths and custom dose amounts. HGH users can switch to IU mode to calculate syringe units from IU-based vial strengths.
💉 What Are U-100 Syringe Units?
A U-100 insulin syringe is marked so that 100 units equals 1 ml. This means each unit equals 0.01 ml. Peptide users often use these markings to measure small injection volumes more easily.
- 10 units = 0.1 ml
- 25 units = 0.25 ml
- 50 units = 0.5 ml
- 100 units = 1 ml
🧪 How Peptide Reconstitution Works
Peptide reconstitution means adding bacteriostatic water to a dry peptide vial. The amount of water added changes the final concentration. For example, adding 2ml of bacteriostatic water to a 10mg vial creates a different syringe-unit result than adding 1ml or 3ml.
More bacteriostatic water creates a weaker concentration and requires more syringe units for the same dose. Less bacteriostatic water creates a stronger concentration and requires fewer syringe units for the same dose.
✅ Example Peptide Dosage Calculation
If a 10mg peptide vial is mixed with 2ml bacteriostatic water, the concentration becomes 5mg per ml. On a U-100 syringe, 1ml equals 100 units. A 0.25mg dose would require 0.05ml, which equals 5 syringe units.
⚠️ Common Peptide Calculator Mistakes
- Confusing mg, mcg, IU, ml, and syringe units
- Forgetting that U-100 syringes use 100 units per 1ml
- Changing bacteriostatic water volume without recalculating
- Using a 0.3ml, 0.5ml, or 1.0ml syringe without checking maximum units
- Assuming every peptide uses the same reconstitution amount

❓ Frequently Asked Questions
How is peptide dosage calculated?
Dosage is calculated by dividing your selected dose by the final concentration after reconstitution. The calculator then converts that volume into exact U-100 syringe units automatically.
How many units is 0.25 mg on a U-100 syringe?
The number of units depends on your vial strength and the amount of bacteriostatic water added. Use the calculator above to instantly determine the correct syringe units for your selected dose.
What is a U-100 insulin syringe?
A U-100 syringe contains 100 units per 1 ml and is commonly used for precise peptide measurement and reconstitution workflows.
How much bacteriostatic water should I add?
Common reconstitution volumes range from 1–3 ml depending on the desired concentration. Adding more water lowers the mg/ml concentration and increases the number of units required per dose.
Does this calculator work for 0.3 ml, 0.5 ml, and 1.0 ml syringes?
Yes. Select the syringe size and the ruler scale automatically adjusts to reflect the correct maximum unit capacity.
What is the difference between ml and units on a syringe?
Milliliters measure liquid volume, while syringe units are the markings on a U-100 insulin syringe. On a U-100 syringe, 100 units equals 1 ml, so 10 units equals 0.1 ml and 50 units equals 0.5 ml.
Can this calculator be used for HGH IU calculations?
Yes. The calculator includes an HGH IU mode. Select HGH (IU), enter the vial strength in IU, choose the bacteriostatic water amount, and enter the desired IU dose to calculate the syringe units.
