The only iOS app that tracks GLP-1s and research peptides in one place — protocols, reconstitution math, supply alerts and an advisor that won't play doctor.
Educational tracking only · Not medical advice
Built for peptides from the ground up — not retrofitted from a generic medication reminder.
Build a schedule per peptide — daily, every-other-day, 5-on/2-off — with reminders and one-tap dose logging. Start from scratch or a curated stack.
Enter vial size, BAC water and your dose — see the exact draw on a live syringe, with an over-capacity warning if the math doesn't fit.
Track every vial and get a heads-up about a week before you run dry — projected from your live protocol, not a guess.
Tap-to-log on an interactive body map that heat-maps recent sites and nudges you to rotate. Never track it on paper again.
Weight trends with BMI context, adherence charts, and a side-effect log you can hand to your clinician as a clean PDF.
Pre-built combinations — Wolverine, GH, GLO and more — with sensible schedules. Spin one up in a tap; you set the doses.
50+ peptides explained without the jargon — mechanism, half-life, side effects and storage. A one-line TL;DR for every one.
Levels, daily rings, weekly quests and streak freezes that keep you consistent — without ever pushing you to over-dose.
An in-app advisor that answers from a verified library in plain English — and hard-refuses to prescribe.
PepBot explains half-lives, mechanisms and side effects like a smart friend over coffee. Ask about your stack and it answers from the verified library — never from thin air.
Log a run of side effects and PepGem gently suggests a check-in with your clinician — with your report ready to share. Drink far too much water in a day and it says something. It's a diary that watches your back, not a scoreboard that pushes you harder.
No sign-up, no email, no analytics, no ads. Everything you enter lives on your device and — if you choose — syncs through your own private iCloud. We never see it. The advisor runs entirely on your phone.
Everything above, in every language the app speaks — English, German, French and Spanish.
No. PepGem is an educational tracking and organisation tool. It never recommends doses — especially for prescription medicines like Semaglutide, Tirzepatide or Tesamorelin — and always points you to a licensed clinician. Always consult a professional before starting, changing or stopping any protocol.
Yes. There's no account and no analytics. Your data is stored on your device and, if you enable it, synced through your own private iCloud that only you can access. Nothing is sent to us.
It performs the arithmetic on numbers you enter — vial size, bacteriostatic water, target dose — and shows the exact draw on a live syringe. It never recommends a dose; always verify the final figure and technique with a licensed provider.
50+ research peptides and GLP-1 compounds, each explained in plain English with mechanism, half-life, side effects, storage and commonly-researched ranges — for education only.
PepGem Pro unlocks the full app for $3.99/week. Purchases are handled by Apple; manage or cancel anytime in your Apple Account settings.
Your whole stack, organised — private by design, and honest to the core.
