Peptide, hormone & supplement interaction checker
Search any two or more compounds across our library of 450+ peptides, hormones, GLP-1s, longevity meds and supplements. We surface documented cautions, mechanisms, and cited sources — the same engine that powers DoseRoutine plans.
Add at least two compounds to check for interactions.
Track the whole protocol, not just the checks
DoseRoutine builds an AI plan around your real stack — dosing schedules, cycle windows, meal timing, injection sites, and reminders that sync to your phone. The interaction checker runs automatically as you add compounds.
