Most peptide apps are reminders with a calculator stapled on. You're running BPC-157, CJC-1295, Ipamorelin, maybe retatrutide, maybe TRT alongside it. Real vials, real money. And the best record of it is a Notes app you forgot to update or a spreadsheet that lost your reconstitution dates. COMPOUND is the protocol intelligence layer for serious operators. Built on published pharmacology and cited research. Not a timer. Not a generic medication app. The instrument your protocol deserves. STACK ANALYSIS* Enter your full protocol: BPC-157, TB-500, CJC-1295, Ipamorelin, GHK-Cu, tesamorelin, retatrutide, semaglutide, tirzepatide, testosterone. COMPOUND's AI-assisted analysis flags interaction patterns, timing overlaps, redundant pathways, and absorption issues, each one cited to peer-reviewed research. Two compounds hitting the same pathway is a wasted vial; you will see it. It reports what it finds. It does not write your protocol. SIDE-EFFECT CORRELATION* Log quick daily check-ins. COMPOUND maps every symptom against your dose timeline and surfaces the patterns you would not find by hand. Insomnia lining up with evening CJC. Nausea tracking a titration step. Mood dips that follow estradiol troughs. BLOODWORK SCANNER* Photograph or import any lab report. COMPOUND extracts every marker (free T, total T, estradiol, IGF-1, CRP, AST/ALT, A1C, lipids, hematocrit) and plots them on your protocol timeline. Told you're "in range" while the symptoms stay? Bring the trend to your next appointment, not the single number. RECONSTITUTION CALCULATOR Stepped input or plain language*: "10mg vial, 250mcg twice daily." Exact syringe units, vial duration, expiry tracking. Unit conversion for the amount you choose; it does not pick your dose. No mental math at 6am. STACK PHARMACOKINETICS* Your whole protocol on one estimated serum concentration curve, built from published half-lives and your own log. Drag a dose time and watch coverage shift across the day. Cycle calendar, cross-cycle comparison, restart readiness check. 90+ COMPOUND REFERENCE LIBRARY Half-life, mechanism of action, regulatory status, protocol patterns reported in the literature, known interactions, and the key studies with PubMed links. 250+ cited studies. Written for people who read the papers. PROTOCOL CHAT* Ask anything about your own stack. Every answer is grounded in your protocol, your symptom log, your bloodwork, and cited research, not a generic chatbot that does not know what you are running. It shows you the evidence; it does not prescribe. ALSO INCLUDED - Dose logging with injection site rotation and timing analysis - Vial inventory and supply alerts* - Symptom journal with pattern detection - Unlimited protocols, reminders, home screen widget - Apple Health sync: sleep, HRV, resting heart rate, workouts, weight, glucose WHO COMPOUND IS FOR - People running multi-compound peptide protocols - TRT users tired of a single number standing in for how they feel - Reta and tirzepatide users who want more than a shot tracker - Anyone who refuses to guess with vials that cost real money - Researchers who already built the spreadsheet and want it on their phone, smarter PRIVACY Anonymous sign-in. No ad-tech. No tracking SDKs. No data resale. IMPORTANT COMPOUND is not a medical device. It does not diagnose, treat, or prevent any condition, and it does not prescribe, recommend, or adjust doses. All analysis is informational, based on published pharmacological research. Always consult a qualified healthcare provider before starting or modifying any protocol or medication. * Requires COMPOUND PRO subscription. Free to start.

Peppy is the peptide tracker that keeps you organized. Log every GLP-1 and peptide dose, see your prescribed dose in the units on your syringe, organize your vials, rotate injection sites, and get gentle reminders so you never miss a shot. No account. No sign-up. Free to start. Peppy is a peptide tracker and logbook. It is not a medical device and it never recommends a dose. You enter the dose you and your provider already decided on; Peppy records it and keeps you organized and consistent. WHY YOU'LL LOVE PEPPY • No account, no sign-up. Open the app and start tracking in seconds • Your health data stays on your device and in your own private iCloud. Never on our servers • Built for GLP-1 and metabolic peptides, branded or compounded, plus custom peptides you add yourself • A peptide tracker with a clean, uncluttered design and a friendly mascot to keep things light • Thoughtful safety reminders at every step TRACK YOUR DOSES A peptide tracker is only as good as its log. Record every injection and see your full history at a glance: what you took, when, and what's next. Back-date a dose you forgot, spot missed doses, and build a streak week after week. YOUR PRESCRIBED DOSE, LOGGED Enter the vial you use and the dose your provider prescribed. Nothing is pre-filled and nothing is suggested: every number is the one you typed, and every screen reminds you to follow your provider's instructions. ORGANIZE YOUR STASH AND VIALS Keep every peptide in one stash, track how much is left in each vial, and watch mixing and expiry dates so nothing goes to waste. Set up a new vial from presets in a couple of taps, and get a nudge when it's time to refill. ROTATE INJECTION SITES An interactive body map records where you injected and suggests your next site, so you rotate properly and never overuse one spot. NEVER MISS A DOSE Daily or weekly reminders that fit your routine and adapt as your schedule shifts. Schedule-aware, so reminders keep pace with the plan you entered. Home Screen and Lock Screen widgets show your next dose and vial levels without opening the app. TRACK YOUR PROGRESS Log weight and symptoms alongside your doses and see clear trends in simple charts, so you and your provider can see how the plan is going. One peptide tracker for the whole picture. SAFETY FIRST Clear disclaimers appear throughout the app, and every dose screen reminds you to follow your provider's instructions. Peppy never recommends a dose, never sources or sells peptides, and never offers medical advice. Always follow the guidance of your licensed healthcare provider. PRIVATE BY DESIGN Your doses, weight, symptoms, and notes are stored on your device and, if you choose, synced through your own iCloud account. They are never uploaded to our servers, and there is no account to create. We collect anonymous, non-health usage analytics only if you opt in, and an advertising-measurement tool runs only if you allow tracking. See our Privacy Policy for full details.
