Vial — Peptide Tracker The most complete peptide tracking app for iOS. Vial helps you manage your protocol with precision — tracking inventory, logging doses, and modeling how compounds move through your body over time. TRACK YOUR PROTOCOL Add any peptide with its vial size, reconstitution volume, and pharmacokinetic parameters. Vial calculates your exact concentration, tracks how much is remaining, and estimates how many days until you run out. LOG DOSES IN SECONDS A floating log button is always within reach. Choose from common dose presets or enter a custom amount, pick your injection site, and you're done. Your inventory updates automatically. SEE YOUR BLOOD LEVELS Vial's pharmacokinetic engine models estimated compound levels in your system over time, based on each peptide's half-life and time to peak. See when levels rise, peak, and decline — all in a clean, interactive chart. UNDERSTAND YOUR TRENDS The Insights tab shows your dose frequency, cumulative intake per peptide, and patterns across 7, 14, 30, and 90-day windows. Tap any bar in the chart to see exactly what you dosed that day. WELLNESS JOURNAL Log mood, energy, nutrition, and side effects alongside your protocol. Spot patterns between how you dose and how you feel. LAB RESULTS Store and track your blood work over time. Keep your protocol and your biomarkers in one place. BODY COMPOSITION Log weight, body fat percentage, and lean mass. Watch your body composition trend alongside your protocol on a built-in chart. RECONSTITUTION CALCULATOR Enter your vial size and BAC water volume — Vial instantly calculates the exact concentration so you always draw the right amount. HOME SCREEN WIDGET Check your inventory and dose status without opening the app. APPLE HEALTH SYNC Write weight and body composition data directly to Apple Health. LOW INVENTORY ALERTS Get notified when a vial is running low so you're never caught off guard mid-protocol. Vial is for personal tracking purposes only and is not a medical device. Estimated blood levels are mathematical approximations based on population pharmacokinetic models, not clinical measurements. Nothing in this app constitutes medical advice.
