Compare the exact selection

Choose the labeled amount per unit and quantity before comparing. A single unit and a multipack have different upfront prices. Keep product format and exact recipe consistent; similar names do not establish equivalent products.

Follow the original listing to check its quantity, availability and current price. Unit prices use the full labeled mass in each selection.

About Retatrutide

Source profile reviewed 2026-10-01 · Imported 2026-10-22. Read the full compound profile

Retatrutide (LY3437943) is an investigational once-weekly injectable peptide that activates the GIP, GLP-1 and glucagon receptors at the same time. It is a 39-amino-acid analog with two Aib residues, an alpha-methyl-leucine, a C-terminal amide and a C20 fatty diacid attached through a linker to lysine 17, which extends its half-life to roughly a week. In phase 2 it produced a mean weight loss of 24.2% at 48 weeks, and the phase 3 TRIUMPH program has reported 25-28% at 80 weeks; it remains investigational, with no approved label or dosing schedule.

Research evidence described in the source

Human

Randomized phase 2 obesity trial

The 48-week trial enrolled 338 adults and compared multiple weekly doses with placebo.

Human

Lower starting doses improved tolerability

Gastrointestinal events were common and were partially mitigated by starting at 2 mg rather than 4 mg.

Review

Still investigational

No approved retatrutide product or public prescribing schedule exists.

Limitations noted in the source

  • Phase 2 results do not establish an approved regimen or long-term benefit-risk profile.
  • Unregulated products labeled retatrutide cannot be assumed equivalent to trial material.
  • A calculator preset is a recorded research convention, not a recommendation or evidence of clinical benefit.
  • Identity, purity, sterility, and stability can vary substantially outside regulated manufacturing.
