Every tool to track, model, calculate, and correlate your protocol. Built for peptide, GLP-1, TRT, and HRT.
Four built-in calculators handle the math for peptides, testosterone, GLP-1s, and intranasal dosing. Stop drawing diagrams on the back of receipts.
Set up your protocol once and Regimen handles reminders, cycling, and the messy scheduling edge cases. You focus on results, not on remembering whether today's a Wednesday dose.
Open the app, see what's due, tap to log. Streaks build automatically. Skipped doses get flagged so you don't lose the thread.
See estimated blood levels for 150+ compounds based on published half-life data. Watch the curve fill and clear with every dose. Know where you are in the cycle, not just what you took yesterday.
This is the part most people end up using Regimen for. The correlation layer pulls your Apple Health and Health Connect data and overlays it against your dose history. Sleep, body fat, weight, heart rate, lab markers. So you can see whether the protocol is moving the needle.
Every peptide, every GLP-1, every common TRT and HRT compound, plus a long tail of niche stuff. Each entry has half-life data wired in so the calculator and PK curves just work. If something's missing, add it yourself with a custom half-life.
Daily check-ins for 50+ markers across wellness, side effects, performance, and recovery. Whatever matters to your protocol gets tracked on a 1-to-5 scale. The data feeds straight into the correlation engine so patterns show up.
Weight, body fat, waist, every body measurement that matters to your protocol. Plotted on the same timeline as your doses. Every dose escalation shows up as a marker so you can see exactly which change moved which metric.
