GrowthUp is where you keep your protocol straight. Enter what you're taking — the compound, the concentration, the schedule — and GrowthUp does the math: exact syringe units for every dose, so you're never eyeballing a line on a barrel. It tracks what's left in each vial, tells you when to reorder, and reminds you on the schedule you set. YOUR PROTOCOL, ORGANIZED - Dosing schedules with reminders that respect your notification settings - Automatic syringe-unit conversion from your vial concentration and reconstitution volume - Remaining-supply tracking and a buy list so you're never caught short - A dose history: what you took, skipped, or missed, and when A REFERENCE LIBRARY, NOT A GUESS - Compound information compiled from published literature and labelling - Interaction notes for the combinations we've encoded - Stack templates across common goals — recovery, performance, longevity, and more — as a starting point, not a prescription GROWTHUP AI Ask questions about your own protocol — dosing math, reconstitution, timing — and get answers grounded in your actual data. You choose what it can see, and nothing you ask is stored on our servers. SHARE WHAT YOU WANT, NOTHING MORE Add friends and choose exactly what they see — your streak, your consistency score, your compounds — one switch at a time. Everything is off by default. Doses and amounts are never shared, with anyone, ever. Post a Moment — a photo, a stat, a quick note — and it's gone in 24 hours. APPLE HEALTH, BOTH WAYS Pull in steps, sleep, workouts, weight, and resting heart rate to see the full picture alongside your protocol — and, if you choose, show them to friends and on the weekly board. BUILT FOR ADULTS, BUILT TO RESPECT YOUR DATA GrowthUp is for users 18 and older. We don't sell your data, we don't run ads, and we don't show your protocol to anyone you haven't explicitly approved. GrowthUp is a personal record-keeping and unit-conversion tool. It is not a pharmacy, a prescriber, a medical device, or a substitute for professional care — nothing in the app, including GrowthUp AI, is medical advice. Always confirm dosing and interactions with a licensed clinician.
