Peptide Vault is the tracking and research companion for people who take their protocol seriously. TRACK Track an FDA-approved GLP-1 (semaglutide, tirzepatide, and other approved GLP-1s): dose schedule, next-dose countdown, streaks, adherence, dose history, and reminders. The Reconstitution calculator does the math for you — vial size and water in, syringe units out. BUILT AROUND YOUR SCHEDULE Pick your first dose day and your schedule patterns from it — weekly, twice weekly, three times weekly, every other day, or every two weeks. Log a dose in seconds. Your history lives on a calendar you can actually read. PEPTIDE VAULT PRO • My cabinet — save vial photos, ingredient amounts, concentrations, mix dates and notes, with cabinet backup and restore. • Custom blend protocols — one schedule and one log for a multi-ingredient vial, with a recorded ingredient breakdown. • Coach — a research assistant grounded in your own protocol. Ask about the published research behind the compounds you track. Coach's answers are grounded in published research, and it never gives dosing or medical advice. • Track unlimited compounds across your whole protocol. • Open all 203 compounds in the research library — every entry referenced, with regulatory status, mechanisms, risks and side effects stated plainly. • Site rotation, suggested at every dose. • Dose history and trends across everything you run. • Journal with full record export, any time. COMMUNITY Join public conversations about app tips and staying organized. Posts and replies are moderated, with likes, sharing, reporting and blocking. Your optional Community profile and posts are stored on our servers; approved posts are public. Private tracking records are not posted automatically. Activity notifications are optional. YOUR DATA No account is required for private tracking. Your protocol, logs, and journal live on your device. Coach shares only what you approve — your compound names and stack summary, never your journal, notes, or Apple Health data. Peptide Vault is a tracking and reference tool. It does not provide medical advice, diagnosis, or treatment. Always consult a medical professional before using peptides.

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 monetization model: Protocol at free against Peptide Vault's subscription. Protocol also leads on update cadence (every 2 days vs weekly). Peptide Vault's advantage is ratings volume (9 vs 1) and device support (3 vs 1). 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 Vault sells 11 in-app purchases, starting at $9.99 per month and Protocol sells 2 in-app purchases, starting at $1.99 per 7 days. 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 Vault against 5.0 for Protocol. That said, the two scores are not equally well evidenced: Peptide Vault has 9 ratings behind it against 1, so its average is the more settled of the two.
Peptide Vault ships an update weekly, Protocol every 2 days. The most recent releases landed on October 12, 2026 and October 2, 2026 respectively.
