According to the data, it has the following pharmacokinetics: Time to max concentration: 8-72 hours Max availability: 80% Half life: 5 days Time to steady state: No details provided With weekly dosing, the graph for Tirzepatide is shown below
As a triple incretin receptor agonist, it: Activates GLP-1 receptors , reducing appetite, slowing gastric emptying, and improving insulin secretion Activates GIP receptors , enhancing insulin response and potentially supporting fat metabolism Activates glucagon receptors , increasing energy expenditure and hepatic glucose output Whilst glucagon receptor activation increases hepatic glucose output, the net glycaemic effect of retatrutide is mitigated by the concurrent GLP-1 and GIP activity, resulting in overall improvements in glycaemic control in trial participants
These represent the highest weight loss outcomes recorded for any pharmacological compound in a Phase 2 clinical trial to date, exceeding both semaglutide and tirzepatide outcomes at equivalent treatment durations
Pregnancy and breastfeeding Insufficient research exists on copper peptide safety during pregnancy and breastfeeding
