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. Optional Pro overlay: literature ranges, cited on screen, labeled educational • Doctor-Ready PDF: protocols, adherence, history and labs in one document CONNECT YOUR BODY • Apple Health, Oura, WHOOP and Withings: sleep, HRV, resting heart rate and weight against your cycles • CGM glucose: time in range, and your glucose curve against your injections • A health score and biological age computed from your own labs TRACK YOUR HOUSEHOLD • Add a partner with their own protocols, logs, bloodwork and insights, kept separate, under one membership • One tap switches between people, a distinct color shows whose data you're viewing, and one shared Vault links vials to either person PRIVATE BY DESIGN • Local-first: your data lives on your device, with optional encrypted cloud backup you control • No ads, no data sales, no social feed WHAT PEPTIDELAB IS NOT PeptideLab is a personal record-keeping and education tool. 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.
