Weekly GLP-1 injections offer a structured once-per-week treatment routine, while daily ODTs provide a needle-free option for patients who prefer an oral dissolving tablet. Understanding the difference helps you choose the semaglutide or tirzepatide format that best fits your goals, lifestyle, and consistency.

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.
