GLP-3 Pen (48mg)

Origin & Classification

GLP-3, also known as a tri-agonist peptide, is engineered to mimic the activity of three endogenous hormones: glucagon-like peptide 1 (GLP-1), glucose-dependent insulinotropic polypeptide (GIP), and glucagon. It consists of a single synthetic peptide chain with amino acid substitutions that confer agonistic properties toward the GLP-1 receptor (GLP-1R), GIP receptor (GIPR), and glucagon receptor (GCGR). The peptide incorporates modifications such as fatty acid conjugation or amino acid substitutions to enhance stability and receptor affinity. It is produced using solid-phase peptide synthesis and, when applicable, chemical conjugation to fatty acids for extended half-life.

Mechanism & Research Context

The tri-agonist interacts with three class B G protein-coupled receptors, leading to activation of multiple intracellular signaling cascades. Activation of GLP-1R and GIPR stimulates adenylate cyclase, increasing cAMP and activating protein kinase A, while glucagon receptor activation can promote both lipolytic and gluconeogenic pathways through cAMP and phospholipase C signaling. Researchers utilize GLP-3 to examine integrated hormonal control of glucose metabolism, appetite regulation, and energy expenditure. Studies explore downstream pathways including insulin secretion, beta-cell proliferation, hepatic glucose output, and mitochondrial biogenesis. By simultaneously engaging all three receptors, GLP-3 provides a tool to dissect cross-talk among incretin and glucagon signaling axes in metabolic and endocrine research.

Composition & Quality

GLP-3 is supplied as a compounded, ready-to-use solution of high purity (>95 %) as determined by reverse-phase HPLC and mass spectrometry. It may include a lipid moiety to allow reversible albumin binding, which extends its half-life in vivo. Manufacturing processes adhere to GMP standards, including purification steps, sterile filtration, and extensive analytical testing. Certificates of analysis document the peptide’s sequence, purity, molecular weight, and stability profile. Storage guidelines recommend refrigeration and avoidance of prolonged exposure to heat or light.
