PepSTAX

PepStax is a private, on-device toolkit for adults researching peptides. It does the math on the numbers you enter and organizes your own reference notes and logs. It does not sell anything, does not give medical advice, and never recommends a dose. RECONSTITUTION CALCULATOR Enter your vial amount and the bacteriostatic water you're adding; PepStax instantly shows the resulting concentration and the volume for any amount you specify. Clear, precise, and unit-aware — no spreadsheets, no guesswork on the arithmetic. EDUCATIONAL COMPOUND LIBRARY Browse a reference library of research compounds with molecular details, mechanism summaries, and cited sources. Educational information only — plainly labeled, with links back to the original references. PROTOCOLS & VIAL ORGANIZER Keep your vials organized: track single compounds or blends, reconstitution dates, and your own review/discard window. See concentration and a countdown at a glance. When a vial runs out, start a new bottle in one tap — PepStax keeps the running history: which bottle you're on, when the series began, and a per-bottle record of your past vials. PRIVATE LOG & TRENDS Record what you do and how you feel — by voice or by typing — with notes and optional check-ins. PepStax charts your own self-reported observations over time. You enter it — PepStax displays it. REMINDERS Optional local reminders for vial review windows and your own schedule. Everything stays on your device. MEMBERSHIP (OPTIONAL) The calculator, library, and core tracking are free. An optional PepStax Membership — $5/month or $48/year, starting with a 7-day free trial — unlocks unlimited vials, advanced insights, cycle tracking, custom reorder alerts, and PDF export. Subscriptions renew automatically unless cancelled; manage or cancel anytime in your store account. PRIVATE BY DESIGN No account. No sign-in. No cloud. All of your data lives on your device, and you can export a backup anytime. FOR RESEARCH USE ONLY PepStax is an educational and reference tool for adults 21+. It is not medical advice and is not intended to diagnose, treat, cure, or prevent anything. Compounds discussed are research materials; nothing in the app recommends, prescribes, or suggests using any substance. Always consult a licensed professional.
