Protocol is the ultimate lab app for your peptide cycles — a premium iOS tracker for people who treat their stack seriously. Log every injection in micrograms, ride the streak, and keep your reconstitution, injection technique, and safety guides one tap away. WHAT YOU CAN DO Build your stack - Add from a curated library of 25+ compounds: BPC-157, TB-500, Tirzepatide, Cagrilintide, Retatrutide, Semaglutide, GHK-Cu, CJC-1295 (no DAC), Ipamorelin, Sermorelin, Tesamorelin, NAD+, MOTS-c, Humanin, SS-31, AOD-9604, Pinealon, Selank, Semax, DSIP, PT-141, KPV, Thymosin alpha-1, VIP, SLU-PP-332. - Configure each entry: dose amount in micrograms, milligrams, or IU; frequency (daily, every other day, twice daily, post-workout, weekly, custom); a color tag; private notes. - Add custom compounds outside the library. Edit or pause any entry at any time. Log doses in one tap - The Today screen shows your full stack. Tap "Log" — the dose is recorded with the right amount, unit, and timestamp. - Mistapped? Undo the last log instantly. - A day badge shows how many doses you've taken for each peptide today (×1, ×2, ×3). Streaks and history - Streak counter on Today and Profile counts consecutive days with at least one dose. - "This week" and "All time" totals sit next to the streak. - Pull to refresh; everything syncs to the cloud the moment you tap. Reminders that match real protocols - Per-peptide reminders: pick times of day, days of week, AM/PM windows, post-workout cues. - Native iOS notifications, respectful of Do Not Disturb and Focus modes. - The Notifications screen logs every reminder fire and streak milestone in one feed. Built-in safety and how-to guide - 10 in-app chapters written for the peptide-curious and the long-cycle stacker: • Important disclaimer — what this app is and isn't • Your first cycle — where to start • Reconstitution — mixing lyophilized peptides safely • Injection technique (subQ) in 6 steps • Storage & shelf life — lyophilized vs reconstituted • Side effects — common, rare, and red flags • Stacking & cycling — combinations that make sense • Bloodwork to monitor — what to test and when • Sourcing & purity — how to verify what you're injecting • Legal status — know what's allowed where you live Tailored from day one - Onboarding asks two questions: what are you here for (recovery, longevity, performance, GH, cognitive, metabolic, sleep, sexual, immune, skin, weight loss) and your experience level (new, some experience, advanced). - Library and protocol suggestions adjust accordingly. Edit goals & experience anytime from your profile. Profile and identity - Display name, handle, bio, avatar. - At-a-glance stats: total doses logged, current streak, active goals. - Sign in with Email or Google. Privacy-first — no social feed, no public timeline, no follower count. WHAT'S INTENTIONAL - No ads, no social feed, no in-app purchases inside the tracker. - Your data stays yours. WHO IT'S FOR - People running 1–5 compounds at a time who keep their dose log in Notes and forget which vial they're three days into. - First-cycle users who want a clean reference for reconstitution and injection technique before they self-experiment. - Long-cycle stackers who want streaks, weekly volume, and full historical doses on tap. DISCLAIMER Peptide is a tracking and reference tool, not a medical device. Nothing in the app is medical advice or a prescription. Consult a qualified physician before starting any protocol.
