It is placed under the tongue or between the cheek and gum, where it dissolves slowly over 15 to 30 minutes, allowing the peptide to absorb through the oral mucosa into the bloodstream

The elemental composition (78 carbons, 123 hydrogens, 23 nitrogens, 23 oxygens, and 2 sulfur atoms) reflects the presence of methionine and cysteine-class contributions to the sulfur count, and provides a useful cross-check when confirming lot identity by mass spectrometry (ESI-MS or MALDI-TOF) against the theoretical [M+H]+ envelope
