Stackr vs Pepmax

Stackr is the simplest way to track peptide and GLP-1 dosing. Log every dose. Track vials, pens, tablets, and other containers with how much you have left. Get reminders for your next dose. See how half-life shapes estimated active levels in your stack over time. Built for peptide enthusiasts, GLP-1 users, and anyone who wants their protocol off paper and into an app that understands supplies and dosing cadence — not a generic habit tracker. WHY STACKR • Fast dose logging — log from home or tap the widget when you're in a hurry • Supplies — track what's in the fridge (vials, pens, bottles, sprays, and more) with amounts, low-stock alerts, and typical dose size so "doses left" stays honest • Multi-peptide stacks — run BPC-157 alongside a GLP-1 (or anything else you track) in one place • Active levels — visualize estimated active amount over time from your logged doses and each peptide's half-life (educational estimate, not medical guidance) • Reminders & widgets — next-dose reminders that respect your schedule; home-screen widgets for what's due PEPTIDE LIBRARY Stackr includes reference pages for the most-tracked compounds — semaglutide, tirzepatide, retatrutide, BPC-157, TB-500, MK-677, GHK-Cu, and more. Each page covers typical dosing, half-life, schedule, route, mechanism, and general education. Educational only — Stackr is not medical advice. REMINDERS THAT FIT YOUR PROTOCOL Set reminders aligned with how you dose — daily, every other day, weekly, or custom intervals. Use widgets to see what's next without opening the app. SYNC ACROSS YOUR DEVICES Sign in with Apple or email and your data syncs across iPhone and iPad. Encrypted in transit. Your dosing history stays tied to your account — no ads, no selling data to third parties. BUILT FOR THE PEPTIDE COMMUNITY: By a peptide user, for peptide users. If something's missing, the in-app feedback channel goes straight to the founder. —— Disclaimer: Stackr is for personal tracking only and does not provide medical advice.

Pepmax is the tracker for people who take their peptide protocol seriously. Most "peptide apps" are a reminder and a notes field. Pepmax does the parts that actually matter: the reconstitution math so you draw the right amount, the on/off cycle structure so you know exactly where you are, and an honest log of every dose you've actually taken. Built for the people who were already doing this in a spreadsheet and a calculator — and knew there had to be something better. It won't tell you what to take. That's not its job. It makes what you've decided to do accurate, organized, and yours. WHAT YOU GET • Reconstitution calculator — enter your vial and target dose, get the exact units to draw. No back-of-napkin mixing. • Fast dose logging — what, where, and when in a few taps, with site-rotation hints so you keep injections varied. • Real cycle tracking — on- and off-weeks with day counters, adherence trends, and a clean summary when each cycle wraps. • Vial inventory — every vial from sealed to active to empty, with doses remaining, storage, and expiry at a glance. • Daily journal — energy, sleep, and soreness on a 0–10 scale, rolled up so you can see how you actually felt. • Reference library — common compounds by half-life and frequency. Reference only, never a recommendation. HONEST BY DESIGN Pepmax is not medical advice. It doesn't recommend compounds or doses, make health claims, sell anything, or tell you where to get anything. Your decisions are your own — talk to a licensed provider before starting or changing a protocol. You must be 18 or older.
