Peptide information is everywhere. Clear sourcing is not. Peptidia is an educational peptide encyclopedia built around published evidence. It helps adults understand what a peptide is, how it has been studied, how mature the evidence is, and what researchers still do not know. Peptidia does not provide medical advice, diagnose or treat any condition, generate protocols, or recommend taking anything. The iOS app does not display specific peptide doses. Always consult a licensed healthcare professional with health questions. WHAT'S INSIDE • 80 curated peptide profiles in English and French • Evidence Passports that summarize research maturity, source depth, strongest source tier, and review date • Direct PubMed, DOI, and clinical-trial links behind factual claims • Research Watch: the library is scanned weekly for literature changes, with optional notifications when something changes • Goal-personalized library ordering so relevant topics surface first • The Peptarch, an assistant grounded in Peptidia's evidence library, with inspectable citations • A private wellness journal for mood, sleep, energy, weight, and notes • No ads, vendors, or affiliate links INTERACTIVE LEARNING Quiz with Peptarch introduces peptide basics through three short rounds, sourced explanations, earned stars, and practice for missed questions. Injection Sites, Explained is a source-backed anatomy reference about commonly described subcutaneous regions, rotation, hygiene, and needle properties. It is educational and does not provide a self-injection walkthrough. Reconstitution Math, Explained makes conversions, concentration, volume, and syringe scales easier to understand. Every field starts empty, calculations use only values entered by the user, and each result shows the formula step by step. Nothing is suggested or saved. RESEARCH WATCH Peptidia checks PubMed and ClinicalTrials.gov weekly for relevant additions. When the indexed literature changes, subscribers who opted in can receive one dose-free digest. New records are clearly distinguished from editorial conclusions. HOW IT WORKS 1. Complete a short onboarding about your research interests. 2. Open a library ordered around those interests. 3. Read an Evidence Passport before exploring a peptide in depth. 4. Inspect the cited source behind a claim. 5. Ask the Peptarch a question and review the studies attached to its answer. 6. Track how you feel in the private journal. Peptidia is for adults 18+. It is not intended for use during pregnancy or breastfeeding, with active cancer, or by anyone under 18.
