Pineal Peptide Extracts (Epitalon Expanded)
A vendor category expanding on the Epitalon concept; the extracts are not a defined substance with published characterization.
Overview
This is a vendor category label for pineal peptide extracts, presented as an expansion of the Epitalon concept. Epitalon is a synthetic tetrapeptide associated with Russian bioregulation research on pineal function and aging, but pineal peptide extracts as marketed here are not a single defined substance, and no peer-reviewed literature characterizes the extracts themselves. Identity and composition are supplier-specific, and the category name reflects catalog organization rather than established pharmacology.
