I made a batch of the stuff and it seemed to work I used it when I went out to take pictures one evening and I never once got winded even though I should have I can't explain how the peroxide losses its odor honestly I don't think it did totally but it still worked. The next batch I make Iam going to use different peroxide I was reading on a site I think it was fastestbows.com I am not sure its on my home computer and it says that you shouldn't use the peroxide in the brown bottle because it has a scent to it. sorry i couldn't be more help when i get home I will post that link.
