What is Retatrutide?

Retatrutide is a synthetic triple-agonist peptide that acts on the GIP, GLP-1 and glucagon receptors at once. It is supplied for research as a pre-filled, multi-dose injection pen.

It is studied in the weight-loss and metabolic research space, where its three-receptor design has produced the largest reductions of the incretin class in published trials. Individual research outcomes vary with dose and duration.

Reported side effects

• Nausea and reduced appetite — the most commonly reported effects in the research literature, usually easing as the dose is titrated slowly.
• Other gastrointestinal effects (fullness, constipation or loose stools) reported at higher doses.
• Mild, transient injection-site reactions.

How to dose Retatrutide

Dosed once weekly and titrated upward slowly — the ramp is 2 → 4 → 8 mg, holding each step for about four weeks, up to a 12 mg once-weekly maximum. The multi-dose pen dials each amount, so no measuring or mixing is required.
