Peptade is the tracker built for peptides and GLP-1s. Log every dose, run schedules and cycles, manage titrations, mark your application sites, file your lab paperwork, and watch your supply count down — with smart reminders so you never miss a log. For personal record-keeping and education only. Peptade is a subscription app: Peptade Premium unlocks all content and features — some plans include a free trial. Prices are shown before purchase, and subscriptions auto-renew unless canceled at least 24 hours before the current period ends. PEPTIDE & GLP-1 TRACKING Set up each peptide or GLP-1 with its total amount, BAC water, reconstitution date, dose and doses per day — fixed dose or multi-step titration. Build weekly schedules or on/off cycles, get a live supply countdown, log each dose and review your full history. Add any compound from the catalog, or your own. APPLICATION-SITE TRACKING Log where you apply on an interactive body map, saved to the exact spot you tapped, then see the week's sites to rotate. VERIFY YOUR COMPOUNDS Scan a vial's code, file its certificate of analysis, and learn to read it: a guide to every field, a completeness checklist, and a batch comparison you answer yourself. Peptade renders no verdict on a document, a vial or a seller — a COA describes a production batch, not the vial in your hand. The one fact it states, with its source, is the compound's regulatory status: FDA-approved for a named indication, or not approved for any medical use. PEPTIDE RESEARCH LIBRARY Browse 150+ researched peptides and GLP-1s with mechanisms, routes, contraindications, regulatory status, sources, and evidence level — "Established Research" or "Emerging Research", describing the research, not safety or effectiveness. Dosing appears only where a compound is FDA-approved, beside its approved indication. PEP BOT ASSISTANT An in-app AI assistant that reads your tracking, so you can ask general educational questions in context. PepBot gives no medical advice, diagnoses or dosing instructions, never states a dose for a compound no regulator has approved, and points you to a licensed provider for health decisions. LIFESTYLE TRACKING Habits that support your goals: · Sleep — bedtime, wake time, quality and an informational Sleep Score · Nutrition — calories, macros and micros, with AI food scanning by photo, menu ranking and barcode lookup · Exercise — workouts, sets and a recovery-aware muscle map · Hydration and body weight APPLE HEALTH Optional two-way sync: read steps, energy, sleep, weight and workouts in; write logged weight, hydration and nutrition back out. HEALTH DISCLAIMER Peptade is for tracking and education only. It gives no medical advice, diagnosis, treatment recommendation or dosing instruction, and it does not sell, source, supply or endorse any compound, vendor or seller. Always consult your healthcare provider about any health decision. Adults 18+ only. PRIVACY Photos and profile data travel over encrypted connections; originals are deleted after 90 days. Row-level security means only you can read your data. Withdraw AI consent, reset your tracking data or delete your account anytime from Settings. Terms of use: https://www.peptade.com/terms

Peptade's advantage is rating (4.8 vs 4.4). On price, review sentiment, ratings volume and update cadence there is nothing between them.
