Metabolic Research Peptides

Peptide Warehouse Australia stocks Retatrutide (GLP-1/GIP/Glucagon triple agonist), Tesamorelin, and L-Carnitine. All are supplied as lyophilised powder at 99%+ HPLC purity for in-vitro research use only, dispatched from our Australian warehouse with full COA documentation.

Retatrutide (LY3437943) is a triple agonist targeting GLP-1, GIP, and glucagon receptors simultaneously. Single-receptor research agonists target GLP-1 only; dual agonists target GLP-1 and GIP. The addition of glucagon receptor agonism in Retatrutide introduces thermogenic and hepatic lipid metabolism mechanisms not present in earlier compounds, making it a distinct research subject. All are for in-vitro laboratory research use only.
