Reconstitution chart FAQ

How do I read a peptide reconstitution chart?

+

Find your vial size in the column header and your dose in the left column. The cell shows how many units to draw on a U-100 insulin syringe. Use the tabs to switch between 1, 2 and 3 mL of bacteriostatic water.

What does a blank or ">100" cell mean?

+

The dose would need more than 1 mL (100 units) at that dilution, which does not fit in one insulin syringe. Use less water or a larger vial, or split the dose.

My numbers are not in the chart. What now?

+

Use the peptide calculator for any combination of vial size, water volume and dose — it works with decimals and also shows the nearest tick mark on your syringe.
