Quick Reference

U-100 Syringe Math

U-100 syringes have 100 units per 1 mL. So 0.05 mL = 5 units, 0.10 mL = 10 units. The tick marks on most insulin syringes represent 1 or 2 units each.

Unit Conversions

1 mg = 1,000 mcg. So 250 mcg = 0.25 mg, and 500 mcg = 0.5 mg. Most peptide doses are discussed in micrograms (mcg).

More Water = Easier Dosing

Adding more BAC water creates a lower concentration, which means you draw more liquid per dose. This makes tiny doses easier to measure accurately.

Storage Reminder

Reconstituted peptides in BAC water last 28–30 days refrigerated at 2–8°C. Sterile water solutions should be used within 24–48 hours. Never freeze reconstituted peptides.
