FAQ
How do I reconstitute a peptide?
Add bacteriostatic water to the vial, then divide your target dose by the resulting concentration. This tool does the math and converts to insulin-syringe units so you draw the right amount.
What does 'units' mean?
On a U-100 insulin syringe, 100 units = 1 mL. The tool gives the units to draw for your dose so you don't have to convert mL by eye.
