Do I need an account to use the pepSmart calculators?

No. Reconstitution math, peptide dosing, and the GLP-1 unit converter are open without an account, sign-in, or ads.

Does pepSmart save my calculator inputs?

Only if you choose to. The calculator runs in your browser; saved vial presets and saved calculations are stored locally on your device only and are never uploaded to pepSmart. No account is required.

How do I convert milligrams to syringe units on a U-100, U-50, or U-40 insulin syringe?

On a U-100 insulin syringe, each 0.01 mL is 1 unit, so multiply the dose volume in mL by 100. A U-40 syringe is graduated at 40 units per mL (1 unit is 0.025 mL), and a U-50 syringe is a half-mL barrel. The pepSmart calculator handles each selection and returns the unit count automatically once vial size, water volume, and target dose are entered.

Why does my calculated GLP-1 dose look different from the pen marking?

GLP-1 pens (e.g., Wegovy, Ozempic, Zepbound) are pre-mixed at concentrations specific to the labeled product. Compounded GLP-1 vials use different concentrations and require unit math against the actual mg/mL after reconstitution.

Are these calculators medical advice?

No. The calculators are educational and run deterministic math against the inputs you provide. Dose decisions belong with a qualified prescriber.
