Track your peptide, GLP-1, and TRT protocol with clarity. Vial is an all-in-one tracker that keeps your vials, doses, schedule, bloodwork, and notes in one private place. Replace spreadsheets and scattered notes with a simple system built for consistency. Vial is for personal tracking, informational and record-keeping only. You enter the dose you were prescribed, and Vial keeps it organized. It never recommends or calculates a dose for you. Supports BPC-157, TB-500, semaglutide (Ozempic, Wegovy), tirzepatide (Mounjaro, Zepbound), retatrutide, CJC-1295, Ipamorelin, GHK-Cu, and any custom peptide. FEATURES Dose Tracking Log every dose with one tap. Three-state logging (logged, skipped, missed), calendar view, and a full year heatmap. Protocol Scheduling Daily, weekly, or custom-interval doses with smart reminders that fire entirely on-device. Cycle scheduling handles on and off weeks. Vial Inventory Track every vial from first dose to last. Expiry and fridge-life alerts so you never use a dead vial. Cost per dose and runway across every bottle. Injection Site Tracker Rotate sites with an interactive body map. Color-coded aging shows what is ready and what to avoid. Side Effect Tracking Log symptoms with severity and review your history to spot patterns tied to a peptide. Bloodwork and Body Metrics Track labs, weight, and body metrics over time with trend charts and progress photos. Apple Health Two-way sync for weight, mood, and side effects, with your permission. Nothing is uploaded to our servers. AI Coach Ask general educational questions about peptides, protocols, and injection technique. The AI coach does not provide medical advice, diagnosis, treatment recommendations, or dosing instructions. Research Library Browse 55+ peptide and GLP-1 profiles with educational summaries and PubMed research links. Export and Reports Export your full dose history to CSV for your spreadsheet or your clinician. Private by Design All your protocol data stays on your device. No account. No cloud sync. No tracking. Your peptide history is yours alone. BUILT FOR EVERY PROTOCOL GLP-1 therapy (Ozempic, Wegovy, Mounjaro, Zepbound, compounded semaglutide and tirzepatide), TRT and HRT (testosterone, HCG, ancillaries), recovery and joint healing (BPC-157, TB-500), growth-hormone protocols (CJC-1295, Ipamorelin, Sermorelin), longevity stacks (Epithalon, NAD+, MOTS-c), and anti-aging (GHK-Cu).

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.

Verdict
The clearest difference is ads: Protocol at none against Vial AI's shown. Protocol also leads on update cadence (every 2 days vs monthly). Vial AI's advantage is iOS requirement (15.1 vs 17.5). On price, in-app purchases and device support there is nothing between them.
