Does semaglutide expire or need refrigeration?

The FDA approved pen products, Ozempic and Wegovy, follow manufacturer storage instructions, generally refrigerated before first use and usable at room temperature for a limited period after. For reconstituted research chemical vials, this site's general reconstitution guidance applies: refrigerate at 2 to 8 degrees Celsius and expect roughly a 28 day usable window once mixed, consistent with how peptide solutions generally behave.
