Stacker vs Peptidemaxx

Stacker is the peptide stack tracker. It's built to help you find the right stack for your goals, dose it correctly, and track whether it's actually working. Most peptide apps stop at "remind me to dose." Stacker takes you from goal → stack → results. BUILD YOUR PERSONALIZED STACK Tell us your goals — fat loss, muscle, recovery, skin, longevity, sleep — and Stacker recommends a named stack (LEAN, GLOW, Wolverine, KLOW) or the individual peptides that fit. Every stack comes with suggested doses, routes, and schedules you can adjust. CURATED STACKS WITH DOSAGE GUIDES Browse proven stacks with clear, per-peptide dosage guidance and difficulty levels — so you know exactly how to run GLP-3, BPC-157, TB-500, retatrutide, tesamorelin and more, not just what they are. TRACK DOSES & PROGRESS Log every dose in a tap, keep your streak, and watch your "Day X of N" protocol progress. Capture progress photos to see changes over time, and run check-ins on the metrics that matter for your goal. DOSING SCHEDULES & SMART REMINDERS Daily, weekly, or custom — Stacker generates the full schedule, anchors it to your real start date, and sends reminders so you never miss a dose. Evening catch-up nudges keep you honest. RECONSTITUTION CALCULATOR Step-by-step: exactly how much BAC water to add and how many units to draw for your dose — paired with a clear subcutaneous injection guide covering technique and site rotation. EXPERT-VETTED PEPTIDE LIBRARY A growing catalog with mechanisms, dosing ranges, cycle lengths, common stacks, and what to watch for — each peptide with Learn, Schedule, and Sources tabs so you go from research to running it in one place.
