Retatrutide 20mg
Retatrutide (LY3437943) is a synthetic 39-residue peptide that activates three receptors at once: GLP-1, GIP and glucagon. The triple action distinguishes it from dual agonists such as tirzepatide and has made it one of the most closely followed compounds in metabolic research. Supplied for laboratory research use only. Not for human or veterinary use.
A triple GLP-1, GIP and glucagon receptor agonist.

What the research shows
Phase 2 results published in the New England Journal of Medicine reported marked effects on body composition. The glucagon-receptor component adds a thermogenic element that GLP-1-only analogues lack.
Studies examine how the triple profile affects appetite signalling, glucose homeostasis and hepatic lipid metabolism. Its pharmacokinetics are well characterised.
