Protocol is built for people who manage a regular routine: testosterone or other hormone therapy, peptides, GLP-1 medicines, prescribed medications or a daily supplement stack. If you track more than one thing, or want your doses and lab results in one place, Protocol is for you. TRT AND PEPTIDE TRACKING • Schedule injections, pens, tablets and oral liquids • Log completed or skipped doses with one tap • See the volume and U-100 syringe units for your saved dose and vial • Built-in reconstitution calculator for recorded vial and diluent values • Record injection sites and see which ones you used recently • Follow every dose and protocol change on one timeline SUPPLEMENTS AND MEDICATIONS • Keep everything you take in one list, with schedules and reminders • Calendar and complete dose history • Find protocols quickly with search and filters BLOODWORK AND HEALTH TRENDS • Import lab reports and keep every result organised by marker • See each result beside its previous value and the lab's range • Compare two reports side by side • Health overview of recent changes across bloodwork and health data APPLE HEALTH AND APPLE WATCH With your permission, Protocol shows supported Apple Health data such as resting heart rate, overnight HRV, sleep, steps and body measurements next to your protocol, compared with your own baseline. Check today's protocol on Apple Watch. PROTOCOL PRO Free includes up to three active protocols, scheduling, reminders, dose history, manual health tracking, one bloodwork report import and local backup. Protocol Pro adds unlimited protocols and bloodwork imports, bloodwork trends and report comparison, vial and pen inventory, Apple Health integration, the Apple Watch app, Protocol Insights, estimated exposure graphs, Physiological Response and HRV views, and PDF and CSV exports. Monthly and annual auto-renewable subscriptions are available. PRIVATE BY DESIGN Protocol is local-first and doesn't need an account. You choose which Apple Health data to share. IMPORTANT Protocol helps you record and understand your own health information. It doesn't diagnose, treat or recommend doses. Estimated values, such as exposure graphs and vial inventory, are calculations from what you record, not measured blood levels. Trends show associations, not cause and effect. Always follow the advice of a qualified healthcare professional.
