1. A molecule selected from the group consisting of:
- (a) a peptide having the amino acid sequence;
##STR2## and (b) a derivative of said peptide (a), wherein said derivative is selected from the group consisting of;
(1) a pharmaceutically acceptable acid addition salt of said peptide;
(2) a pharmaceutically acceptable carboxylate salt of said peptide;
(3) a pharmaceutically acceptable lower alkyl ester of said peptide; and
,(4) a pharmaceutically acceptable amide of said peptide wherein said pharmaceutically acceptable amide is selected from the group consisting of amide, lower alkyl amide and lower dialkyl amide;
wherein said molecule is substantially free of natural contaminants, and has an insulinotropic activity which exceeds the insulinotropic activity of GLP-1 (1-36) or GLP-1 (1-37).
