Common drugstore variety of 3.5% H2O2 as Brooks post said. Check the archives for his post on 7/6/09. In a message dated 8/12/2013 4:35:56 A.M. Pacific Daylight Time, ptf2...@bellsouth.net writes:
Did you use H2O2 from a drugstore or did you get the variety from a health food store and dilute it down? PT Recommend ONLY Food Grade H2O2, unless you're into absorbing phenol, acetanilide, acetanilid,sodium stanate, and tetrasodium phosphate. Thanks but no thanks. I have yet to experience a bad reaction to any of Brooks Bradleys protocols. If you can improve his protocols go for it. Brickey
