Tirzepatide Dosing: 0.5mg 3x/Week Split (2026)

Split dosing cuts GI side effects vs once-weekly โ€” here’s the math. Covers 0.25-0.5mg 3x/week, titration, and reconstitution.

Tirzepatide is a dual GLP-1/GIP receptor agonist that represents the next generation of incretin-based therapies. By targeting both GLP-1 and GIP receptors, it provides superior weight loss and glycemic control compared to single-target GLP-1 agonists like semaglutide.

FDA-approved as FDA-approved for diabetes and weight management with clinical data showing up to 22.5% weight loss in the SURMOUNT trials.

Research peptide protocols use a 3x weekly approach with lower total doses than pharmaceutical formulations:

Start at 0.25 mg 3x weekly for 2-4 weeks to assess tolerance, then increase to 0.5 mg 3x weekly. The split dosing provides more stable levels than once-weekly injection.

For the full tirzepatide peptide profile, vendor pricing, and stack protocols, see our Tirzepatide peptide page.

Loading (Weeks 1-4): Start at 0.25 mg three times per week (0.75mg total weekly) to assess tolerance. The dual GLP-1/GIP mechanism can cause more intense initial side effects than single-target agonists.
