Read full description

Peptide Protocol is a shot log for people following a peptide or GLP-1 routine their clinician set. Log every dose in seconds: the compound, the amount you took and the injection site, exactly as you enter them. Get reminders at the times you choose. Rotate injection sites with a body map that shows where you went last. Keep track of your vials: what you have on hand, mix and expiry dates, and refill alerts before you run out. Check in on energy, sleep, appetite, side effects and weight, and see your own logs side by side week by week. Works for semaglutide, tirzepatide, BPC-157, CJC-1295, ipamorelin, GHK-Cu and 30+ more compounds. Pause a protocol with a return date and it picks up again on the day you choose. Your records stay on your iPhone. IMPORTANT Peptide Protocol is a personal log. It does not compute, suggest, recommend or adjust doses, and it does not provide medical advice, diagnosis or treatment. Enter the dose and amounts your prescriber gave you, and talk to a qualified healthcare professional before any medical decision.

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.
