Need to know your concentration first?
Use the Reconstitution Calculator to find your concentration based on how you mixed your peptide.
How to Use This Calculator
- Enter your desired dose – This is how many micrograms (mcg) of peptide you want to take.
- Enter your concentration – This is your solution strength in mcg per ml. Get this from the reconstitution calculator or your mixing notes.
- Draw the units shown – The result tells you how many units to draw on a 100-unit insulin syringe.
The Formula
Units to draw = (Desired dose ÷ Concentration) × 100
This formula works because a U-100 insulin syringe has 100 units per ml. So if you need 0.1ml of solution, you draw 10 units.
Quick Reference Examples
| Desired Dose | Concentration | Units to Draw |
|---|---|---|
| 250 mcg | 2,500 mcg/ml | 10 units |
| 500 mcg | 2,500 mcg/ml | 20 units |
| 250 mcg | 5,000 mcg/ml | 5 units |
| 1,000 mcg | 2,000 mcg/ml | 50 units |
Frequently Asked Questions
Small volumes are difficult to measure accurately. Consider using more bacteriostatic water when reconstituting to create a lower concentration. This will result in a larger, easier-to-measure volume for the same dose.
This calculator assumes a U-100 insulin syringe (100 units = 1ml). If you're using a different syringe, use the ml result instead and convert to your syringe's markings.
Round to the nearest whole number or half-unit marking on your syringe. Small variations in volume are generally acceptable. If precision is critical, adjust your reconstitution ratio to create easier-to-measure doses.
