Tirzepatide
Tirzepatide (LY3298176) is a synthetic dual agonist at the GIP and GLP-1 receptors, supplied as a pre-loaded multi-dose injector pen for research and laboratory use only.
With a molecular weight of approximately 4,813 g/mol, it is among the most extensively studied compounds in metabolic research — including the SURMOUNT-1 trial published in the New England Journal of Medicine. Published pharmacology attributes its distinct profile to combined activity at both incretin receptors rather than GLP-1 signalling alone.
Every batch is HPLC-verified by an independent laboratory. Certificates of Analysis are published on the product page as each batch is verified — ask us if you need the report for a specific batch. Store at 2–8 °C in the dark.
