// ABOUT
Dosii is a peptide reconstitution calculator. Enter three things — your vial size, your dose, and how much water you added — and Dosii shows you exactly where to draw on your syringe. That's it. One screen. No sign-up. No menus to learn. WHAT IT DOES • Shows the exact fill line on a 30u, 50u, or 100u insulin syringe • Suggests water amounts that give you clean, even doses • Calculates cost per dose when you enter the vial price • Supports mg, mcg, and IU dosing units • Works with pre-mixed compounds (testosterone, etc.) WHAT IT DOESN'T DO • No data collection — zero analytics, zero tracking • No accounts — open the app and start calculating • No cloud — everything stays on your device • No subscriptions — pay once, own it forever Built for people who reconstitute their own peptides and want to stop doing math in their head every time they dose.
