How to track it in Peptimes

Add SLU-PP-332 in My Protocols and set the schedule you already follow: days of the week, times of day and a start date. Peptimes never suggests an amount when you log or schedule a dose. Its Library entry shows the status label “Not FDA-Approved”.

  • Routes: its route isn’t established in people, so you can choose any route the app offers. Choose the one that matches each dose.
  • Logging: the amount you took, the route and how you feel.
  • Injection sites: injected doses record the site, and Insights shows where you’ve injected and how recently. It never suggests where to inject next. Other routes skip this step.
  • Reminders and history: reminders at your times, Dose History, the Calendar and CSV or JSON export work as described on the peptide tracker app page.

Peptimes is a tracking app, not medical advice. Talk to a licensed clinician about your treatment. Peptimes doesn’t sell SLU-PP-332 or any other compound.
