While I am no fan of H2O2 it will not get past your stomach and you will burp O2. H2O2 is a normal metabolite in your cells produced as a result of ATP production, normally dealt with by reducing agents such as glutathione. There is no way in hell that H2O2 taken orally will get to your cells, except maybe the odd cells in the stomach lining. Why on earth would anyone want to take H2O2???
