PeptideMax is the fastest way to stay on top of a peptide protocol — built for people who are tired of spreadsheets, syringe math, and missed doses. YOUR NUMBERS, CONVERTED Enter what's on your vial, the bacteriostatic water you add, and the dose from your own protocol. PeptideMax instantly shows your concentration, exactly how many units to draw on your syringe, and how many doses your vial holds. A converter, not a guide — the app never suggests compounds, doses, or schedules. SCHEDULES THAT MATCH REAL PROTOCOLS Daily, weekly, specific days, every-N-days, on/off cycles, and multi-phase plans that change over time. Set it once — your home screen always knows what's next. REMINDERS THAT WORK A heads-up before each dose, an alert at dose time, and a follow-up if you haven't logged it. Log from the notification in one tap. SEE WHAT'S IN YOUR SYSTEM An estimated in-body level curve based on your logged doses and each compound's half-life, so you can see peaks and troughs at a glance. STAY CONSISTENT Streaks, a week strip, and a monthly calendar of logged, scheduled, and missed doses. Injection-site rotation tracking included. YOUR DATA STAYS YOURS Dose history and health details are stored on your device — there is no PeptideMax server holding your data. PeptideMax is a tracking tool, not medical advice. Dosing decisions belong to you and your healthcare provider. Requires a subscription. Terms of Use (EULA): https://usepeptidemax.app/terms Privacy Policy: https://usepeptidemax.app/privacy

Verdict
The clearest difference is monetization model: PeptideMax at free with in-app purchases against Stacksy's subscription. Stacksy's advantage is ads (none vs shown) and update cadence (every 2 days vs every 8 days). On price, ratings volume, in-app purchases and device support there is nothing between them.

Stacksy ships an update every 2 days, PeptideMax every 8 days. The most recent releases landed on October 11, 2026 and October 6, 2026 respectively.
