Limitless Life is the simplest way to run and track a peptide protocol alongside the body metrics that actually tell you whether it's working. Log your stack, check off doses, record your weight, sleep, resting heart rate, waist, mood, and energy, then watch it all come together in clean, readable charts. Everything lives in one place, on your phone, private to you. TRACK YOUR STACK - Build your stack from a built-in peptide library or add your own - Enter vial strength and BAC water, and the app calculates your exact syringe units to draw - Set flexible schedules: daily, weekly, every few days, cycles, or twice a day - Check off each dose and see your active protocol at a glance SEE WHAT'S WORKING - Plot any metric over time with smooth, easy-to-read charts - See dose days and dose changes right on the timeline - Add notes to any day and find them again on the chart - Choose any range from one week to a full year, or pick a custom date range LOG YOUR BODY - Enter weight, body fat, resting heart rate, waist, sleep, mood, and energy - Import automatically from Apple Health so you don't have to type - Add dated progress photos and watch your changes over time - Set goals and get a simple read on your trajectory STAY CONSISTENT - Build a daily logging streak - Optional dose reminders and a weekly weigh-in nudge - Twice-weekly motivation, personalized from your own trends PRIVATE BY DESIGN Your health and dosage data is yours. It is never used for ad targeting and never sold. Data imported from Apple Health is used only inside the app. Limitless Life is free, supported by ads. Limitless Life is a personal tracking tool. It does not provide medical advice and does not sell or supply any substance. Always consult a qualified healthcare professional about your health and any protocol you follow.
