What Peptisy does

The app records the information you enter, calculates reconstitution arithmetic, and creates reports. The website offers the same core calculations without requiring an account.

  • Dose and vial records
  • Reconstitution and syringe-unit arithmetic
  • Half-life decay estimates from values you enter
  • Appointment-ready history reports

What Peptisy does not do

Peptisy does not select a compound, recommend a dose, diagnose a condition, or replace a healthcare professional. Research-compound pages keep their regulatory status visible.

Privacy by architecture

There is no Peptisy account and no Peptisy health-data server. App data stays on the device and may sync through the user’s private iCloud database. Website calculators run locally in the browser.

Who is behind the content

Product documentation and calculator explanations are currently written and source-checked by the Peptisy product team. Independent medical, legal, and native-language reviews are tracked separately and are never implied before they occur.
