Peptide's Playbook is the all-in-one companion to organize and track your peptide protocols — built for clarity and privacy. START WITHOUT AN ACCOUNT Open the app and you are already in. Browse all 59 compounds and the synergy map with no signup, no email, nothing. An account is only asked for when you want to save a stack or a log — and it is free. WHAT MAKES IT DIFFERENT Every figure in the app shows where it came from: each of the 59 compounds carries a visible, tappable citation. The app never calculates or recommends an amount — you enter the units you draw yourself, and the app keeps them, shows them, and counts them down. YOUR COMPLETE TOOLKIT • Today: what is up next, in big numbers — the units you entered — plus the day's list and how many applications are left in every vial • Reference library: 59 compounds with cited sources, profiles, categories, and synergies • Your vial: enter the units you draw and keep for your own record; the app counts them down with every log • Weekdays: pick the day for each weekly compound, or the days for 2x, 3x or 5x a week • Left in the vial: already used part of one? Enter the units left and the vial picks up from there • Daily tracker: log applications, sites, notes, and how you feel • Progress charts: weight and metrics over time • Site rotation map: avoid overuse with a visual guide • Reminders: at the time you chose for each vial • Cloud sync: your data on all your devices • Bilingual: full English and Spanish support ALSO ON YOUR COMPUTER Your free account includes the web version at getpeptideplaybook.com — the same library, your stack and your log, on the big screen and in sync with your iPhone.
