YOUR BODY’S RESPONSE, ON AUTOPILOT — The Readout connects Apple Health and puts your HRV and resting heart rate beside your private research log. No manual entry. Ask the Professor about your own trends and get a clear, research-grounded explanation of what your numbers did — never medical advice, never a protocol. PeptideU is a peptide education and personal-research app. It teaches and it records — it never prescribes. Think of it as a university for peptides: a structured curriculum, a cited AI professor, and a private log to track your own research. WHAT'S INSIDE Ask the Professor Ask what a peptide is or what the research says. Every answer is grounded in cited sources — never dosing or personal medical advice. The Curriculum Work through a structured video curriculum, Freshman to Graduate. Pass each module's quiz to rank up toward your Peptide Mastery credential. The Library An evidence-first reference on dozens of peptides — mechanism, the science with real, verifiable citations, and where each one stands. Independent, reader-funded, no affiliates. Your Research Log Keep a private log of your own research — what you looked into, when, and your own observations. Your notes stay yours. Descriptive insights only: counts, streaks, and patterns — no recommendations. COA Scanner (Premium) Upload a Certificate of Analysis and the Professor reads it field by field — compound, purity, method, lab — in plain language, with a checklist to verify it yourself. Document analysis, not a verdict. Live Coaching & Office Hours (Premium) Join live sessions with coaches, ask questions in real time, and catch replays in the Vault. The Commons A community space to compare notes and vote on what to cover next. EVIDENCE-FIRST, ALWAYS PeptideU is for education and personal research only. It is not medical advice, it does not recommend or prescribe any substance, and it sells no peptides. The only purchase is a PeptideU membership. Premium unlocks the COA Scanner, live coaching, the full curriculum, and more. Membership is billed through your Apple ID. SUBSCRIPTION PeptideU Premium is an auto-renewable subscription: $9.99 per month or $99.99 per year. Payment is charged to your Apple ID at confirmation of purchase. It renews automatically unless auto-renew is turned off at least 24 hours before the end of the current period. Manage or cancel anytime in your Apple ID account settings.
