PeptideStack

Read full description

Track your peptide protocol, GLP-1 medication, and injection routine in one clean, private journal. PeptideStack is built for people who take their regimen seriously and want a focused log, not a spreadsheet and not a medical guide. YOU ENTER EVERY NUMBER PeptideStack never recommends, suggests or works out a dose. The dose field starts empty and is labelled "Your dose": you type your own amount, and the app simply records what you entered and when. WHAT YOU CAN DO • Build your stack from a curated catalog of 69 commonly studied peptides — BPC-157, TB-500, GHK-Cu, Semaglutide, Tirzepatide, Retatrutide, Cagrilintide, CJC-1295, Ipamorelin, MK-677, Tesamorelin and more — or add your own entries. • Log a dose fast: choose the peptide, type your amount, and save. A normal day takes seconds. • Get a reminder at the time you choose, on the days you choose. Reminders run on your phone and keep working offline. • Track the vial you are using: the amount in it, the date you opened it, a discard-after date, and how much is left based on the doses you log. • Follow a cycle: how many weeks in you are, and when the break starts. • Record how you are doing — body weight, sleep, energy, recovery — and watch the trend on a chart. • Export your dose history and your progress to a spreadsheet whenever you want. • Review your full history, grouped by Today, Yesterday, Earlier this week, and Earlier. • Add a note to any dose — what you noticed, how you felt, anything worth remembering. • Change your password any time from Settings. • Use it in your language: English, German, French, Spanish, and Arabic, with full right-to-left layout for Arabic. WHO IT IS FOR • People keeping a personal record of a peptide regimen they manage themselves. • People tracking GLP-1 medication already prescribed by their healthcare provider. • Researchers, biohackers, athletes, and anyone who wants a clean log instead of scattered notes. PRIVACY FIRST Your stack and dose history are encrypted in transit and at rest, and tied to your account so nothing is lost when you change phones. We never sell your data. Delete your account from Settings at any time — your data is removed within the published grace window. PEPTIDESTACK PRO (OPTIONAL) Free: dose logging, your full history, one reminder, and up to 3 peptides. Pro adds: • Reminders on every peptide in your stack, not just one • Vial tracking — amount remaining and a discard date • Cycle tracking — the week you are in and when the break begins • Progress charts for body weight, sleep, energy and recovery • Export to a spreadsheet • An unlimited number of peptides • Monthly: $4.99 / month • Annual: $29.99 / year (save ~50%) • Lifetime: $79.99 (one-time) 7-day free trial on the subscription plans. Cancel anytime in Settings → Apple ID. Subscription auto-renews unless cancelled at least 24 hours before the end of the current period. IMPORTANT PeptideStack is an educational tracking tool. It does not provide medical advice or diagnosis, and it never recommends or suggests a dose — every dosage, frequency, and amount is one you entered yourself. You are responsible for your own decisions. Always consult a qualified healthcare professional before starting, changing, or stopping any peptide regimen.
