Products/GLP-3 RT
Vendor-neutral comparison

Metabolic research

GLP-3 RT

Prices checked September 10, 2026

Research synopsis

Previously known as “Reta” on S7 Sciences. GLP-3 RT is designed to switch on three hormone signals involved in appetite, blood sugar, and energy use. In a phase 2 human trial, participants with obesity lost substantial weight, but the compound remains investigational and its long-term safety is still being studied.
