Take the guesswork out of tracking your protocols. Biohack is an all-in-one peptide and compound tracker designed to help you organise schedules, record doses, plan cycles and understand your progress over time. Whether you are tracking one compound or managing a more detailed protocol, Biohack gives you a clear, private and easy-to-use place for every dose, reminder and progress update. TRACK EVERY DOSE Quickly record completed doses and keep a reliable history of your activity. View what is scheduled today, what you have already logged and what is coming next. SMART REMINDERS Create one-time or recurring schedules and receive local reminders directly on your device. Biohack helps you stay organised without relying on notes, spreadsheets or memory. Record the location used for each entry and view your recent site history. Built-in rotation guidance helps you avoid repeatedly selecting the same area. CYCLE PLANNING Set start and end dates for your protocols, schedule time on and off, and keep every stage clearly organised in one place. TITRATION SCHEDULES Create gradual changes over a schedule you define. Plan increases or decreases in advance and let Biohack display the correct scheduled amount at each stage. COMPOUND LIBRARY Explore a built-in reference library containing common peptides and compounds, including general information and half-life data. Need to track something that is not included? Create your own custom compound and enter the details that are relevant to you. ESTIMATED ACTIVE LEVELS Visualise estimated active levels over time using your logged history and the compound’s entered half-life. These charts are mathematical estimates intended to help you understand how recorded doses may overlap. They are not blood-test results or measurements of actual levels in your body. BODYWEIGHT TRACKING Record your bodyweight in kilograms or pounds and view changes on a simple progress chart. See your weight history alongside your wider tracking activity. PRIVATE PHOTO PROGRESS LOG Build a visual timeline by adding progress photos to your private log. Compare changes over time without mixing personal progress images into your standard photo library.
