The natural, non-D-retro-inverso (non-DRI) parent peptide from which FOXO4-DRI - the engineered senolytic research peptide covered elsewhere on this site - was derived. Unlike FOXO4-DRI, plain FOXO4 lacks the cell-penetrating, protease-resistant design that gives its DRI counterpart systemic bioavailability. Compare FOXO4 prices from $75 across 22 indexed vendors, with per-mg pricing and third-party COA verification.
