Why your peptide vial might not contain what it says

Peptide purity is the percentage of a vial's contents that consists of the intended amino acid chain, measured by high-performance liquid chromatography (HPLC). The figure reflects how cleanly a synthesis... Read more...

Why GLP-1 peptides degrade faster than your freezer thinks

GLP-1 peptides are short chains of amino acids engineered to bind the same receptors as the naturally occurring hormone glucagon-like peptide-1. Semaglutide binds that single receptor. Tirzepatide binds two receptors... Read more...
