Track your peptide journey and check the evidence behind the claims. Peptidia brings a private Lab together with a source-backed peptide encyclopedia. Keep personal records organized, follow your observations over time, and explore research with the Peptarch as your guide. YOUR PRIVATE LAB • Record products, amounts, routes, and subcutaneous sites. See your day's records beside an anatomy map. • Convert amounts using the concentration and syringe scale you enter. • Keep a journal of mood, energy, sleep, and personal notes. • Connect Apple Health, if you choose, to view weight, resting heart rate, sleep, and steps. Glucose and blood pressure are separately optional. • Explore dated observations and trends. Changes over time do not establish that a peptide caused them. • Organize vials in a visual Vault. Record fridge or freezer history, preparation details, and dates from your label or pharmacy instructions. • Set private check-in and vial-date reminders. New Lab records are encrypted on your iPhone, excluded from backups, and never sent to Peptidia's servers or the Peptarch. Apple Health access is read-only and optional. Earlier cloud journal entries are copied into the Lab once, automatically; their server copies remain until account deletion. RESEARCH YOU CAN CHECK • 80+ curated peptide profiles in English and French • Research Watch, with weekly literature checks and optional alerts when indexed evidence changes • Evidence Passports showing research maturity, source depth, strongest source tier, and review date • Direct links to PubMed, DOI sources, and clinical trials • A library ordered around your research interests • The Peptarch, a research assistant with citations you can inspect • No ads, vendors, or affiliate links LEARN WITH THE PEPTARCH Explore sourced anatomy and measurement references, or test your understanding in short quizzes with explanations and practice for missed questions. Educational math starts with empty fields and uses only the values you enter. A guided, animated welcome introduces Evidence, Peptarch, Learn, and the Lab. Your research interests still shape the library. Peptidia provides education and personal recordkeeping. It does not provide medical advice, diagnose or treat conditions, generate protocols, or recommend taking anything. Library content and AI responses do not provide specific peptide doses. Consult a licensed healthcare professional with health questions. Vial records and reminders do not establish product safety or shelf life. Peptidia is for adults 18+. It is not intended for use during pregnancy or breastfeeding, with active cancer, or by anyone under 18. SUBSCRIPTION Peptidia Pro Monthly: $9.99/month, no free trial. The subscription automatically renews unless canceled at least 24 hours before the end of the current period. A limited $59.99 lifetime option may be available.
