PepSeek is the all-in-one peptide research database and protocol tracker for biohackers, longevity researchers, and athletes. Look up any research peptide, see how strong the evidence behind it actually is, and keep track of what you're running. Covers Semaglutide, Tirzepatide, Retatrutide, BPC-157, TB-500, CJC-1295, Ipamorelin, Sermorelin, Tesamorelin, Epithalon, GHK-Cu, and nearly 200 more. 200+ PEPTIDE PROFILES Every major research peptide, with mechanism of action, research status, researched dosing ranges, administration methods, and half-life. Written in plain language, not abstract-speak. EVIDENCE LEVELS Every peptide is labeled well studied, emerging, or limited data, so you can tell decades of literature from a single mouse study. Research sources link straight to PubMed. This is the part other peptide apps leave out. 75 STACK PROTOCOLS Curated combinations for healing and recovery, fat loss, muscle growth, cognition, longevity, sleep, and immune support. Each one explains what's in it and why those peptides belong together. PEPBOT AI ASSISTANT Ask anything in plain English and get an answer grounded in the research. Powered by Claude. PROTOCOL LOG Track what you're running, see what's due today, and log doses as you go. Syncs between your phone and pepseek.app. RECONSTITUTION REFERENCE A nine-section guide covering bacteriostatic water, storage and handling, syringe basics, and the mistakes people make most often. FAVORITES Save peptides and stacks to your own library for quick reference. BUILT FOR IPAD Two-pane search and a full stacks grid on the bigger screen. PRIVACY Search, peptide profiles, stacks, favorites, and the reference guide all work without an account. Only the protocol log asks you to sign in, because it syncs your data between your phone and the web. We don't sell your data, and we never will. WHAT IT COSTS PepSeek has two separate purchases. A free preview is available before you buy either one. Research, $14.99 paid once. 200+ peptide profiles, 75 stack protocols, evidence levels and PubMed citations, favorites, and free updates as new peptides are added. No subscription, no expiry.
