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.

Serious tracking for peptides, GLP-1, TRT and HRT, with the bloodwork to see what actually changed. A precision instrument for people who run their own peptide, GLP-1, HRT and TRT protocols. Record an injection, a pill or a spray in a few taps, or let scheduled protocols run on auto-pilot. Log your workouts, water, meals and periods in the same place. Local-first and private. No efficacy claims, no gamification, no guilt. TRACK PROTOCOLS • The largest compound library in any tracker: peptides, GLP-1s, hormones and supplements • Record what you take in seconds, with titration schedules and cycle calendars • Injection-site rotation on a body map, with recently used sites marked before you pick one • Modeled Exposure: an estimate of what's on board now and where each blood draw fell on the curve • Adherence history and a verdict when a cycle ends TRACK YOUR PERIOD • Log periods, symptoms and waking temperature, with a calendar and a dial that shows where you are in your cycle • Perimenopause and menopause read from your own logs, including a hot flash count • Birth control reminders. Fertile days and ovulation are shown as estimates only, never as birth control • Your cycle data is never used for analytics LOG YOUR WORKOUTS • A library of 250+ exercises, each with a short demonstration of how it's done • Last time's numbers beside every set, a rest timer, and personal records marked as you hit them • Starter templates, a workout calendar, and progress charts for every exercise FOOD AND WATER • AI food log: type or photograph a meal, review the estimate, correct it, approve. Nothing logs without your review. • One-tap repeat meals, recipes, serving sizes, and targets you set yourself • Log water in a tap from the app, a widget or Siri, with reminders through the day KEEP INVENTORY • Vault: fridge, freezer and shelf zones, cap colors, and supply runway tied to your protocols • Photograph a kit's packing list to add vials in bulk UNDERSTAND YOUR BLOODWORK • Import lab PDFs or photos and confirm every value before it counts • Trends across every report and every lab, with printed originals always preserved • Ranges shown are the ones printed on YOUR report.

It is not a medical device and does not provide medical advice, diagnosis, or treatment. It never recommends, suggests, or changes a compound, an amount, a schedule, or a protocol. Every protocol in the app is one you enter yourself. Always consult a licensed clinician before you start, change, or stop any protocol or supplement. PeptideLab Pro (subscription) unlocks unlimited protocols, Modeled Exposure, the Lab Assistant, bloodwork trends and the Doctor-Ready PDF, Apple Health, Oura, WHOOP and Withings, CGM glucose reports, health score and DEXA body composition, household profiles, Food Log photos, protocol reports, and full history beyond 30 days.
