Where it sits
Research peptides are short amino-acid sequences supplied either as a lyophilised powder in a sealed vial or already in solution in a pre-filled pen. Which of the two you receive changes how the item is stored and how long it stays usable once opened.
Other names
Glutathione is also written as GSH and L-glutathione. The same molecule appears under more than one name, which is worth knowing when comparing listings between suppliers.
