None of the three compounds have safety data in this context

These findings suggest that research into the therapeutic modulation of FOXO4 activity, such as through the use of the synthetic peptide FOXO4-DRI, could provide insight into the heart's natural protective mechanisms and degenerative changes associated with aging
