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?

No. The calculator runs in your browser. Inputs and saved vial presets are stored locally on your device only and are not uploaded to pepSmart.

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

On a U-100 insulin syringe, each 0.01 mL is 1 unit, so multiply the dose volume in mL by 100. On a U-50 syringe the line spacing differs; the pepSmart calculator handles either 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.
