The standard FDA tirzepatide dosing schedule moves through six weekly dose levels: 2.5mg, 5mg, 7.5mg, 10mg, 12.5mg, and 15mg, with at least four weeks between steps. This guide walks the week-by-week ladder for both injection and oral compounded tirzepatide, the milligram-to-unit conversions for compounded vials, missed-dose rules, and how the GIPR rs1800437 genetic variant can inform titration pace before week one.

What's common, what's serious, and how to manage GLP-1 side effects from FDA-labeled known information — including the boxed warning that applies to both semaglutide and tirzepatide, when to call your provider, and how PlexusDx structures titration and the optional Precision Peptide Genetic Test.
