RETA Research

Weight & Metabolism Observations

RETA has been examined in Phase 2 research trials. Published findings suggest:

  • Study subjects receiving the 12 mg dose showed average weight reductions of 24.2% over 48 weeks, compared to 2.1% in the control group

  • RETA demonstrated greater observed effects than semaglutide in comparative research

  • Observed outcomes were comparable to results reported in semaglutide and tirzepatide studies


Blood Sugar Observations

In research involving study subjects with Type 2 diabetes:

  • HbA1c reductions of up to 2.2% were observed

  • This effect is associated with RETA’s activity across multiple receptor pathways


Mechanism of Action

Research suggests RETA activates three receptor types:

  • GLP-1 Receptors

    • Associated with insulin release, gastric emptying rates, and satiety signaling in study models

  • GIP Receptors

    • Associated with insulin production and improved insulin sensitivity in laboratory observations

  • Glucagon Receptors

    • Associated with increased energy expenditure and enhanced fat oxidation in metabolic studies


Cardiometabolic & Organ Function Observations

Published research suggests observations beyond weight-related parameters, including:

  • Changes in lipid markers, including triglycerides, LDL, and VLDL

  • Observed blood pressure changes in diabetic and obese study groups

  • Improvements in kidney function markers, including filtration rates

  • Reductions in liver enzyme levels (ALT) and hepatic fat content in study models
