Stop guessing your protocol. AI Coach with cited research, bloodwork analysis, dose tracking, and a 12-zone injection map — the precision tool for serious peptide users.
Pepti is the precision tracker for compounded GLP-1s, Retatrutide, and research peptides - with an AI Coach.
Log every dose. Rotate injection sites across 12 zones. Read your bloodwork in context.
AI COACH (Pro)
Powered by Claude, Anthropic's AI. Ask anything about peptide pharmacology: how compounds work, what their half-lives mean, why certain peptides are commonly paired, what published research says about a compound's effects.
The Coach knows the science. Ask why GHK-Cu pairs with BPC-157, why CJC-1295 and ipamorelin are commonly co-administered, what a rising IGF-1 means. Answers grounded in pharmacology and your logged history - not a generic health chatbot. Every response includes citations to published research. The Coach does not recommend personal doses; clinical decisions are referred to your healthcare provider.
12-ZONE INJECTION SITE HEATMAP (Pro)
Track every injection across 12 anatomical zones - abdomen, thighs, glutes, delts. Pepti shows where you last injected and visualises rotation history.
BLOODWORK READING (Pro)
Upload your lab results and Pepti displays them against published reference ranges. The Coach explains what biomarkers mean - IGF-1, SHBG, hsCRP, testosterone, metabolic markers, liver function - referencing published research.
WHOOP + APPLE HEALTH (Pro)
Connect your WHOOP recovery data - HRV, resting heart rate, daily strain, sleep. Apple Health syncs steps, active calories, and HealthKit data. See how your logged compounds correlate with performance.
PRIVACY BY DESIGN
Your stack stays on your device, synced privately via your own iCloud. When using the AI Coach, your messages and selected app context are sent to Anthropic to generate responses; you must explicitly consent before any data is shared, and you can revoke consent at any time in Settings. No data sold. No ads. Built by an independent developer.
30+ COMPOUNDS
Compounded semaglutide, tirzepatide, retatrutide, GHK-Cu, BPC-157, TB-500, ipamorelin, CJC-1295, tesamorelin, NAD+, selank, semax, thymosin alpha-1 and more — with half-life data, mechanism of action, and administration routes for each.
WHO IT'S FOR
Built for users managing their own peptide protocols - compounded GLP-1s, research peptides, TRT, or a full longevity stack. If you want a free shot-reminder app, better options exist. If you want a precision instrument and an AI with deep pharmacology knowledge, Pepti is built for you.
