Calculator FAQ
What is an insulin syringe unit?
A standard insulin syringe has 100 units per mL. 1 unit = 0.01 mL = 10 microlitres.
How much bacteriostatic water should I add?
Typical reconstitution uses 1-3 mL of bac water per vial. Concentration is a trade-off: less water = smaller volumes but finer dose resolution; more water = larger, easier-to-measure volumes.
Why does the calculator show units, mL, and mcg?
Research peptides are dosed in mcg or mg, but syringes are marked in units or mL. The calculator converts between all three based on your chosen concentration.
