What Is GL-3?
GL-3 is the PROpeptides designation for our advanced triple-receptor metabolic support system studied for its effects on:
- Appetite regulation
- Glucose metabolism
- Energy expenditure
- Weight management
- Metabolic flexibility
- Body composition optimization
GL-3 is unique because it targets multiple metabolic signaling pathways simultaneously, including:
- GLP-1 receptor activity
- GIP receptor activity
- Glucagon receptor activity
This multi-pathway approach has generated significant interest in metabolic and body composition research.
