Semaglutide is the original GLP-1 weight-loss peptide and one of the most-counterfeited peptides on the Australian grey market. We test it constantly.
GLP-1 receptor agonist
Also known as: Ozempic / Wegovy active
Why test Semaglutide?
Counterfeit semaglutide has been documented globally. LC-MS confirms it is actually semaglutide; quantitative HPLC confirms the labelled mg is in the vial.
Common issues we find
Wrong peptide - labelled semaglutide, actually liraglutide or generic peptide
Under-fill
Mannitol-only vials with little to no active
Frequently asked questions
How is semaglutide tested?
LC-MS for identity (confirms molecular weight matches semaglutide), HPLC for purity (% pure peptide), and Quantitative HPLC against a reference standard for actual mg content.
