What semaglutide is
Semaglutide is a long-acting GLP-1 analogue first characterised in metabolic-research literature for its prolonged receptor occupancy and once-weekly pharmacokinetic profile. As a research compound it ships as a lyophilised powder for reconstitution with bacteriostatic water.
Typical research handling
Lyophilised semaglutide is stored refrigerated; once reconstituted, most laboratories follow a 28-day in-use stability window with strict cold-chain handling. Cross-reference COA values for purity, peptide content and water content before any experimental protocol.
Why purity matters
HPLC purity below 99% can indicate truncated sequences or process residues. Every Regena batch ships with an independent COA and mass-spec confirmation — see the lab reports page for the latest batch documentation.
Related GLP-1 research compounds
Researchers comparing receptor selectivity often look at tirzepatide (GLP-1/GIP dual agonist) and retatrutide (GLP-1/GIP/glucagon triple agonist). The Peptide Library lists all three with current batch data.
