Semaglutide 20 mg — GLP-1 Agonist

(356 reviews)
99.2% Purity
$149.99per 20 mg · lyophilized

Semaglutide is a 31-amino acid GLP-1 analogue with a C18 fatty acid chain attached via a linker to lysine at position 26, enabling strong albumin binding and extending plasma half-life to approximately 7 days. It demonstrates high selectivity and potency at the GLP-1 receptor and has been used extensively in preclinical models studying glucose homeostasis, appetite regulation, gastric motility, cardiovascular protection, and neuroprotection. For research use only — not for human consumption.
