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.

Evidence levels are now accurate across the whole catalogue. Well-established compounds like insulin, glucagon, liraglutide and octreotide were reading Emerging when they should have read Well studied. Fixed. Pro Yearly now includes the full research database. Once your first year bills, it's yours to keep even if you cancel later. ### 1.2 — 2026-08-09 Version 1.2 is the biggest update since launch. NEW: PROTOCOL LOG Track what you're running, see what's due today, and log doses as you go. It's the My Log tab. NEW: TWO WAYS TO BUY Research is $14.99 once for the peptide database, stacks, evidence levels, and PubMed citations. Pro is $4.99 a month or $39.99 a year for the protocol log, dose tracking, and PepBot. If you already bought PepSeek, you keep both. Nothing changes for you. BUILT FOR IPAD Search is now two panes, list on the left and the peptide on the right. Stacks get a proper grid instead of a stretched phone layout. REDESIGNED THROUGHOUT A new clinical light theme, rebuilt search with compact rows and a letter rail for jumping through the catalog, and cleaner peptide and stack pages. PepBot now shows which peptide you're asking about. CLEARER EVIDENCE LEVELS Emerging is now blue. Well studied, Emerging, and Limited data read as green, blue, and red at a glance, instead of two shades that looked alike. BIGGER RECONSTITUTION REFERENCE Six new sections, nine in total, covering bacteriostatic water, storage and handling, syringe basics, and the mistakes people make most often. FIXES Double-tapping to log a dose no longer creates two entries, and a log that fails now retries. PepBot stopped printing broken tables. Onboarding buttons and slide layout are fixed, and the counts in onboarding copy are correct. Safe areas, status bar, scroll position, and citation contrast are all corrected across the app. Motion now respects Reduce Motion in your accessibility settings. ### 1.1 — 2026-07-05 - Updated preferred supplier - Improved purchase syncing across devices - Minor fixes and improvements ### 1.0 — 2026-05-15 No release notes. ## More apps by Risen Works LLC - [VerseAid](https://appshunter.io/ios/app/verseaid/id6760314568) All apps by Risen Works LLC: https://appshunter.io/developer/1883794824 --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
