Third-generation GLP
Why Retatrutide is getting so much attention
Retatrutide is a next-generation triple agonist designed to activate GLP-1, GIP, and glucagon pathways. That broader signal may support appetite control, blood-sugar regulation, and higher energy expenditure in one weekly peptide.
Three metabolic targets
Semaglutide focuses on GLP-1. Tirzepatide adds GIP. Retatrutide adds glucagon activity as a third pathway.
Clinical data is impressive
Phase 2 obesity data showed dose-dependent average weight loss, with the highest-dose group reaching about 24% at 48 weeks.
Built for serious goals
Designed for customers looking for broader appetite, metabolism, and weight-loss support in one weekly GLP plan.
Most ordered
Weight-loss pens
