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

  1. Enter your desired dose – This is how many micrograms (mcg) of peptide you want to take.
  2. Enter your concentration – This is your solution strength in mcg per ml. Get this from the reconstitution calculator or your mixing notes.
  3. 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.

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.
