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.

Peptocol is a private iPhone and iPad tracker for GLP-1 and peptide protocol records, shot logs, reminders, and injection-site history. KEEP YOUR RECORDS TOGETHER Organize user-entered protocols, log shots, review site history, and keep notes alongside your records. REVIEW YOUR TRACKING HISTORY See logged activity, streaks, weight and step trends, progress photos, and relative activity charts. Charts describe your records, not treatment results. CALCULATOR AND SUPPLY RECORDS Use the calculator with details you enter. Keep supply records and export your tracking history. Calculator outputs are not recommendations about what to take or when to take it. REFERENCE LIBRARY Browse sourced educational compound summaries. Reference material only, not medical advice. YOUR RECORDS STAY ON YOUR DEVICE The contents of your records are not uploaded: plans, shot logs, amounts, weights, notes, photos, and Apple Health data stay on your device. No account is required and there is no cloud sync. Usage analytics are off unless you turn them on. The app asks once, and you can change your answer any time in Settings > Privacy. If you turn them on, the app sends which screens and features you use, such as that a shot or check-in was logged and when, and subscription activity, under a random ID. It does not send what is in your records. Peptocol Pro provides access to protocol tracking, charts, supply records, exports, progress photos, and the reference library. Trial eligibility and subscription terms are shown on the paywall. Records only. Not medical advice. Peptocol does not diagnose, treat, prescribe, or replace advice from a licensed clinician.
