How Dosii Works
Three inputs. One answer. No account required.
1
Enter your vial and dose
Tell Dosii how much peptide is in your vial (mg), how much you want to inject per dose (mg or mcg), and pick your syringe size. Dosii suggests the best BAC water amount so your dose lands on a clean syringe tick.
2
See the calculated syringe line
An animated syringe presents the calculated line for your selected syringe (30u, 50u, or 100u). Below it, a card shows the mathematical result in units and mL.
3
Know your cost per dose
Enter what you paid for the vial. Dosii shows how many doses you get and what each one costs. That's it. Open the app, get your answer, close it.
