Amylin (also called islet amyloid polypeptide, or IAPP) is a 37-amino acid peptide hormone co-secreted by the beta cells of the pancreas alongside insulin, typically in response to meals
There are many well-studied peptides not available in the U.S., like Semax, a peptide for stroke victims, and Selank, prescribed for anxiety
As with many investigational compounds, potential risks, interactions, product quality concerns, and side effects may not be fully understood
