GLP-3 R – 5mg-30mg (Lyophilized Peptide) – For Research Use Only
GLP-3 R is a novel research peptide categorized within the glucagon-like peptide (GLP) family, studied for its potential activity on metabolic regulation, appetite control, and glucose homeostasis. While structurally distinct from GLP-1 analogs, GLP-3 R is being investigated for its potential interactions with GLP receptor pathways and its role in energy balance, insulin sensitivity, and weight management.
This compound is part of emerging research aimed at expanding the understanding of gut hormone analogs and their effects on metabolic disorders.
