About PepStack – Biohacking Tracker
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.
