I have just ordered my second tub of Oxy-powder capsules as they are fantastic. I had been using the Colosan powder for the last year but my body wasnt tolerating it very well. However, no such problems with the Oxy-powder.
I also have found that its results are not quite as violent as the Colosan and therefore I can take it without worrying about being close to the loo for the whole of the next day! Highly recommended product - thanks for bringing it to my attention.
