How to track it in Peptimes
Add Livagen 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”. It is a separate Library entry from Vilon.
- Routes: the app lets you record whichever route you used; none is established. Its routes are subcutaneous, intramuscular, oral, sublingual, nasal, topical and Other.
- Logging: the amount you took, the route and how you feel.
- Injection sites: subcutaneous and intramuscular 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 Livagen or any other compound.
