AI Peps is a private research log for tracking peptide research entries, reconstitution math, and personal schedules — built for biohackers, researchers, and self-quantifiers who want one organized place for their notes. Important: This app is provided for research and educational purposes only. It is not medical advice, not a diagnostic tool, and not a substitute for a licensed healthcare provider. The compounds referenced are research compounds and are not approved by the FDA (or equivalent regulators) for human use, treatment, diagnosis, or prevention of disease. WHAT YOU CAN DO • Schedule reminders — Set your own recurrence (daily, every-N-days, specific weekdays, weekly) and get reminders so you don't lose track of your research log entries. • Site rotation tracker — A visual body map for logging which site you used for each entry. Helpful for keeping your records organized. • Research literature library — Browse a catalog of 55+ research peptides with mechanism summaries, reported research ranges from published literature, and peer-reviewed citations linked directly to PubMed and journal sources. • AI insights — Optional pattern analysis across your own logged entries: adherence to your schedule, site rotation patterns, and research-log consistency. Insights are observations on your own data, not medical recommendations. • Apple Health integration — Optionally read weight and workout data from HealthKit to keep all your self-tracking in one view. • Private and secure — Your research log is stored privately in your account and never sold or shared. AI Peps includes auto-renewable subscription options for AI Peps Pro. Subscriptions renew automatically unless canceled at least 24 hours before the end of the current billing period.

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.

Verdict
The clearest difference is update cadence: Peptide Tracker at every 2 days against PepSeek's every 5 weeks. Peptide Tracker also leads on ratings volume (5 vs 1). PepSeek's advantage is iOS requirement (15.0 vs 17.0). On price, rating, ads and in-app purchases there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Peptide Tracker sells 2 in-app purchases, starting at $7.99 per month and PepSeek sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
On the App Store both sit at effectively the same score — 5.0 for Peptide Tracker against 5.0 for PepSeek. That said, the two scores are not equally well evidenced: Peptide Tracker has 5 ratings behind it against 1, so its average is the more settled of the two.
Peptide Tracker ships an update every 2 days, PepSeek every 5 weeks. The most recent releases landed on October 23, 2026 and October 6, 2026 respectively.
