New: track any peptide, not just GLP-1. Log your pins, watch your weight trend down, and see your projected goal date — all in one private, beautifully simple app. Agonist is a calm, private place to plan and run your peptide and GLP-1 protocol — map your titration from the first dose to your goal, log every dose and injection site, and actually see your progress. BUILD YOUR PLAN, START TO FINISH Lay out your dose plan rung by rung — every step-up, on the dates you choose. Agonist charts how your plan will play out in your system weeks ahead and reminds you when each step is due. You enter the plan; Agonist visualizes it. (Always your own schedule — never a recommendation.) SEE WHAT'S IN YOUR SYSTEM An estimated "in your system" curve for each compound. From your logged doses and each compound's half-life, Agonist models how much is active over time, so you can watch your levels rise and taper between doses. (An estimate for personal tracking — not a clinical calculation.) A PROTOCOL FOR EACH COMPOUND Every peptide gets its own schedule — daily, weekly, every few days, or specific weekdays — color-coded and organized. Agonist reminds you exactly when each dose is due, and tells you where you last injected so you can rotate sites. LOG A DOSE IN SECONDS Record amount, injection site, and notes in a couple of taps. Your full history — and your adherence — is always a glance away. YOUR WEIGHT, CLEARLY Follow your trend on an interactive chart, set a goal (and re-baseline for a fresh cut anytime), see your total change, and get a projected date based on your real rate of progress. SHARE YOUR PROGRESS Turn a milestone into a clean, branded card — your trend, total change, and goal — ready to post to your story or send to a friend. STAY CONSISTENT A consistency heatmap turns weigh-ins into a streak you'll want to keep — on whatever cadence you choose, from daily to weekly. AT A GLANCE Home-screen widgets show your next due dose and your weigh-in consistency without opening the app. YOURS, EVERYWHERE Create an account to securely back up and sync across your devices.
