Retatrutide has a reported plasma half-life of ~6 days in human pharmacokinetic studies, supporting weekly dosing schedules in research protocols. The extended half-life comes from albumin binding via the molecule's fatty acid side chain modification.

Retatrutide is one of several GLP-1 receptor agonists in active research. QSC also stocks semaglutide and tirzepatide for comparative studies. All ship from the same QC pipeline so cross-compound comparisons don't carry batch-to-batch confounders.
