35% H2O2 is highly reactive & has a short shelf life even when stabilized... some of the health food stores here did sell unstabilized 35% a few years back, but by 2019, could not find it.
BTW every concentration over the ʻnormalʻ 3% should be handled as an unstable, potentially explosive chemical....
ETA MSDS for review.... if no can, no can!
