Peptide Hub vs PepSeek

Find your perfect peptide stack. Look up any compound, compare protocols, track research, and skip the bro-science noise. Built for biohackers who want the real data fast. The peptide database covers a wide range of compounds, each with detailed profiles including mechanism of action, administration forms, typical research dosages, cycle structures, and known synergies. You can search and filter by compound, goal, or administration route to find what you are looking for quickly. The stack builder lets you construct and manage multi-compound research protocols from scratch. You can set dosages, frequencies, timing, cycle durations, and ramp-up or taper phases for each compound in a stack. Once configured, the app tracks your active cycle and displays which phase you are in at any given time. Notes can be added at the stack or compound level so your observations stay organized alongside your protocol. The compare tool allows you to place two or more compounds side by side and evaluate them across objectives you define. A compatibility scoring system generates a ranked result based on your selected goals and experience level, making it easier to reason through compound selection for a given research context. Blood work tracking is built into the app as well. You can manually log biomarker values across panels including hormones, thyroid, metabolic markers, lipids, liver and kidney function, inflammation, vitamins, and iron. Reports can be titled and dated, and the app displays normal range indicators alongside your values to help contextualize results over time. The vendor comparison feature aggregates availability and pricing across multiple research suppliers, filtered by your preferred administration form. This gives you a straightforward way to compare sourcing options without visiting multiple sites individually. All data you enter, including your profile, stacks, blood work reports, and preferences, is stored locally on your device. Nothing is transmitted to external servers. Your health data stays private by design. Peptide Hub is an informational and educational resource only. All peptide compounds referenced within the app are intended strictly for in-vitro research and laboratory use. Nothing in this app constitutes medical advice or guidance for human use. All features require a in-app subscription Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

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.
