Stacker vs PepTrack

Stacker is the peptide stack tracker. It's built to help you find the right stack for your goals, stay consistent, and track whether it's actually working. Most peptide apps stop at "remind me." 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 a clear schedule you can adjust. CURATED STACKS Browse popular stacks with clear overviews, timelines, and difficulty levels — so you understand GLP-3, BPC-157, TB-500, retatrutide, tesamorelin and more, not just their names. TRACK YOUR ROUTINE & PROGRESS Log each dose you take 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. SCHEDULES & SMART REMINDERS Daily, weekly, or custom — Stacker builds your schedule, anchors it to your real start date, and sends reminders so you never miss a log. Evening catch-up nudges keep you honest.
