Tesamorelin is a synthetic analog of growth hormone–releasing hormone (GHRH) designed to interact with the GHRH receptor and support research into endocrine and metabolic signaling pathways. Structurally derived from the endogenous GHRH sequence, it is widely studied in preclinical and translational models examining growth hormone axis regulation, receptor-mediated signaling, and peptide-hormone communication. When you buy Tesamorelin from Bluum Peptides, you receive a high-purity research compound verified by independent third-party laboratories, including Janoshik, to ensure data integrity and reproducible results. Free U.S. shipping is available on qualifying orders. Available Sizes: Tesamorelin is supplied as a high-purity lyophilized powder in multiple sizes to accommodate various research scales and experimental protocols: Tesamorelin 5 mg Tesamorelin 10 mg Tesamorelin 20mg
