Protokol keeps your peptide routine organized in one place — your schedule, your logs, and clear educational reference material, without spreadsheets or scattered notes. HOW IT WORKS Answer a few questions about your goals and experience level, and Protokol matches you with compounds the published research relates to your goals. You set your own schedule — which days, how often — and enter the amounts you're using. Protokol keeps the record and reminds you. WHAT'S INSIDE • Your Own Schedule — pick the compounds, days, and amounts yourself; Protokol never calculates or suggests them • Injection Logging — record what you took, when, and where, in a few taps • Compound Library — research-based reference information on peptides, mechanism, safety, and regulatory status, with published sources you can open and read • Scientific References — every compound and article links to the peer-reviewed studies, FDA notices, and clinical guidance behind it • Mixing & Storage Guides — step-by-step articles on reconstitution technique, syringe types, storage and travel, with listen-aloud audio • Daily Tracking — wellness check-ins and progress photos, private and secure • Ask Pepto, the AI research assistant — ask general questions about peptides, storage, and research anytime, always with a linked source IMPORTANT Protokol does not calculate, suggest, or display doses or schedules. Every amount and every schedule in the app is entered by you. The Compound Library shows mechanism, safety information, and published sources — never a dose range or regimen. Ask Pepto will not tell you what to take, how much, or how often; it cites its sources and points you to a licensed clinician. Nothing in Protokol is medical advice. FREE AND PREMIUM A free account lets you track and log one compound. Protokol Premium unlocks: • Ask Pepto, the AI research assistant • Tracking more than one compound at a time • The full compound library and every guide • Wellness check-ins and progress photos • Your full history calendar • Your complete research summary • Sharing your stack • Read-aloud audio for articles BUILT FOR BEGINNERS Protokol is designed for people who are new to peptide research and want a straightforward, organized way to keep track of what they're doing.

Verdict
The clearest difference is in-app purchases: OOG at none against Protokol's 6. OOG also leads on ads (none vs shown) and chart position (#202 vs unranked). Protokol's advantage is update cadence (every 4 days vs every 2 weeks) and iOS requirement (15.1 vs 17.0). On price, rating, review sentiment and device support there is nothing between them.
