Metabolic Peptides
Mitochondria-derived peptide researched for metabolic regulation, insulin sensitivity, and exercise capacity.
Retatrutide (LY3437943) is a synthetic acylated peptide that acts as a triple agonist of the glucose-dependent insulinotropic polypeptide (GIP) receptor, glucagon-like peptide-1 (GLP-1) receptor, and glucagon receptor. It represents one of the most advanced classes of incretin-based research compounds. Research has investigated its roles in metabolic regulation, energy homeostasis, and adipose tissue biology. PGNA Labs supplies Retatrutide in lyophilised form. A Certificate of Analysis (COA) is available for download on the product page.
