Pinealon is a short peptide consisting of just three amino acids. It is one of a handful of synthetic peptides referred to as peptide bioregulators for their ability to interact directly with DNA to alter gene expression levels. Pinealon has been linked to behavior modification and is thought to help protect a number of cell types, including neurons, against the effects of hypoxia. By direct effect on the pineal gland, pinealon may reduce problems with drug metabolism, circadian rhythm disorders, memory, learning, and more.
