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.
