PepStack – Stacks, Vitals, Blood & Training Plan your stack. Track your progress. See what actually works. PepStack is built for people who take their supplements seriously — and want to see how their stack relates to their body, blood and performance. Instead of five apps and a spreadsheet, it’s all in one place, neatly connected and fully private. Four areas, one picture: Stacks Build custom supplement stacks: compound, amount, dosage, schedule and phases — exactly how you run them. A visual plan shows what’s due when, and reminders make sure you never miss a dose. Vitals Connect Apple Health or Health Connect to pull in steps, sleep, resting heart rate, HRV and more automatically — or log your own metrics by hand. See how your routine shows up in daily life. Blood Log your blood tests — manually or via photo/PDF scan — and keep 100+ markers in view. With a plain-language marker wiki, personal reference ranges, trend charts and a side-by-side comparison of two tests (improved / worse / stable). Training Log your workouts, sets and progress and close the loop: stack, recovery and performance in one app. Everything in context The real value isn’t single numbers — it’s the full picture. Watch how your stack, vitals, blood markers and training move together over time, and make better decisions for yourself. Private by design Sensitive data is end-to-end encrypted — only you have access. Secure cloud backup & sync across your devices. No data sales. Your data is yours. Full stop. Who’s it for? Biohackers, athletes, self-optimizers and anyone ready to move their supplement routine from sticky notes to a clean, data-driven system. Stop guessing. Start tracking. Get PepStack.

PeptidePal is a peptide and GLP-1 protocol tracker used by over 150,000 people — dose logging, vial inventory, injection site rotation, reconstitution math, scheduling, and a 110+ compound library in one app. Whether you're on a prescribed GLP-1, running your first protocol, or managing several compounds on different schedules, PeptidePal keeps it all in one place. WHY PEPTIDEPAL? ◉ BUILT FOR PROTOCOLS, NOT PILLS: Generic medication apps track one pill, once a day. PeptidePal handles mcg, mg, IU and mL, cycles, on/off weeks, site rotation, and vial lifecycle. ◉ NO DRIFT: Three weeks in, it's easy to lose track of whether you're on day 9 or day 12. PeptidePal keeps the protocol you designed and the protocol you're running the same thing. MAIN FEATURES: ▶ PROTOCOL BUILDER Build from the library or from scratch. Set dose (mcg, mg, IU, mL), frequency (daily, every other day, twice weekly, 5-on/2-off, custom), days, start date, notes, and reminders. Run multiple protocols side by side. ▶ DOSE LOGGING & CALENDAR One tap to log. A week strip and monthly calendar show completed and planned doses, injection site, and time. Streaks keep you consistent. ▶ VIAL INVENTORY & SUPPLY ALERTS Log fill size, concentration, and expiry. PeptidePal projects each vial's run-out date from your live schedule and warns you about a week ahead. ▶ RECONSTITUTION MATH Enter vial size, diluent volume, desired amount, and syringe size. PeptidePal does the mg/mL arithmetic and shows it on a syringe diagram, with an over-capacity warning. Unit conversion only — PeptidePal does not recommend a dose. ▶ INJECTION SITE ROTATION Tap-to-select on an interactive body map, with recently used sites heat-mapped so your rotation is visible at a glance. ▶ COMPOUND LIBRARY 50+ profiles in plain English: mechanism, half-life, research status, reported side effects, and considerations. Every entry states its regulatory status. ▶ PROGRESS & LEVELS Weight and body-composition charts, progress photos with compare and time-lapse, and an estimated on-board level curve from your logged doses. Educational estimate, not a measurement. ▶ AI ADVISOR & COMMUNITY Q&A Short, plain-English answers to educational questions, plus a moderated peer forum. The AI will not recommend a dose, titration, or protocol, and routes medical questions to a provider. You're talking to an AI, not a clinician. Does PeptidePal work with prescribed GLP-1s? Yes — track Ozempic®, Wegovy®, Mounjaro® or Zepbound® with the same scheduling, rotation, and supply tools. Dosing decisions belong with your prescriber. Is my data safe with PeptidePal?

Verdict
The clearest difference is ads: PepStack at none against PeptidePal's shown. PepStack also leads on update cadence (every 2 days vs every 5 days) and iOS requirement (15.5 vs 18.0). PeptidePal's advantage is chart position (#150 vs unranked). On price, in-app purchases and device support there is nothing between them.
