Can I track two peptides at once?
Short answer: yes, but most GLP-1 apps cannot. The popular trackers are built around a single medication, so people who add TRT, NAD+ or a second peptide end up running two apps or falling back to a notes file. What you need is one app where each compound keeps its own schedule, its own reminders, its own level curve and its own injection site history.
Why single-medication apps break down
A weekly GLP-1 is simple on its own. Add a second prescribed injectable and everything doubles: a different frequency (daily, every 3 days, 5 days a week), a different form (vial and syringe instead of a pen), different units (IU or mcg instead of mg), and its own rotation between sites. Squeezing that into an app that assumes one weekly pen means fake entries, mislabelled doses and reminders that fire on the wrong days. The record stops being trustworthy, which defeats the point of keeping one.
What proper multi-compound tracking looks like
- Independent schedules: weekly for the GLP-1, every N days or specific weekdays for the second compound, each with its own reminder times
- Per-compound history: every dose logged against the right medication, so your GLP-1 titration record stays clean for your prescriber
- Separate level curves: each compound has its own half-life, so each gets its own estimated curve rather than one misleading blend
- Shared site rotation awareness: both compounds draw on the same body, so the app should see all recent sites when suggesting where to inject next
- The right units per compound: mg for one, mcg or IU for another, without conversion gymnastics
How PepLevel handles it
PepLevel was designed for exactly this person: the GLP-1 user who added a second prescribed injectable and found their old app had nowhere to put it. The free tier tracks one medication fully; Pro removes the limit, and every medication keeps its own schedule, reminders, level curve, dose history and site history. It stays a medication tracker, not a biohacker encyclopedia: you add the compounds your prescriber gave you, enter their schedules, and the app does the remembering.
Every injectable, one calm app
Independent schedules, curves and site history per medication. Coming soon to the App Store.
