Pepstack helps you take the right supplements at the right time, built around your real routine, not a generic label. HOW IT WORKS Tell Pepstack your goals, your diet, and anything that's bothered you before. It builds a personalized shortlist from a catalog of real, sourced products, every pick shows the reason it was chosen, whether that's your goal, your diet, or a reaction you flagged. YOUR SCHEDULE, NOT A GENERIC ONE Add anything to your daily schedule and Pepstack places it around your actual day, your meals, your sleep window, instead of just a flat list of times. Known timing conflicts (like zinc and iron needing space between them) are flagged before they become a problem. BUILT ON REAL RESEARCH Every product in the catalog links back to real, verifiable research citations, not marketing copy. Ask a question and get an answer sourced from that same catalog, with a way to report anything that looks wrong. A REFERENCE LIBRARY, NOT A DOSING TOOL Pepstack also includes a peptide reference library for research purposes: what each one is, its general category, and research trends. It does not provide doses, protocols, or injection guidance for peptides. TRACK WHAT YOU ACTUALLY TAKE Log what you've taken, see your streak, and export your own data whenever you want. Your account and everything in it can be deleted at any time, right from the app. Pepstack works offline for your day-to-day tracking and syncs when you're back online.
