Body Pharm Reta 64mg

Overview

Body Pharm Retatrutide 64 mg is the larger-quantity pen in the Retatrutide range: a sealed, pre-filled multi-dose research pen containing 64 mg of retatrutide (LY3437943) in solution. It is intended for laboratories running extended or multi-arm protocols that would otherwise require several 32 mg pens from different batches.

The pen is a laboratory research material. It is supplied strictly for laboratory research and is not for human or veterinary use. It is not a medicine, food, dietary supplement or cosmetic, and no medical, therapeutic or performance claims are made or implied. No dosing information is provided.

Research background

Retatrutide is a synthetic 39-amino-acid peptide that acts as a single-molecule agonist at the GIP, GLP-1 and glucagon receptors, carrying a C20 fatty-diacid side chain for albumin binding [1]. It is used in the laboratory as a tri-agonist reference ligand in receptor-signalling assays and in preclinical energy-metabolism models where glucagon-receptor activation is a variable of interest [1][2].

The 64 mg and 32 mg pens contain the same compound at the same concentration; only the fill quantity differs. Both are covered in our receptor pharmacology comparison and the Retatrutide monograph.
