Triple GLP-1, GIP and glucagon receptor agonist

Retatrutide is a single synthetic peptide that activates three receptors at once: GLP-1, GIP and glucagon. That combination is what separates it from the earlier incretin compounds, which act on one receptor (semaglutide) or two (tirzepatide). It was developed by Eli Lilly and is still in Phase 3 clinical trials, so the only form that exists is research material like this vial.

The 15mg vial sits between the 10mg and 20mg formats at $12.00/mg. It suits mid-length protocols that would outgrow the smaller vial without needing the largest.

The full research summary, mechanism and legal status are on the Retatrutide page.

Key research areas

  • Adiposity — Total and visceral fat mass endpoints in the Phase 2 obesity trial
  • Energy expenditure — The glucagon-receptor contribution studied by indirect calorimetry in preclinical work
  • Glycaemic control — HbA1c and fasting glucose in the Phase 2 type 2 diabetes cohort
  • Cardiometabolic markers — Blood pressure, triglycerides and liver-fat fraction as secondary endpoints
  • Comparative pharmacology — Head-to-head modelling against semaglutide and tirzepatide
