Hey. Maybe I will try either colosan or Oxypowder then. I liked Oxypowder better just from the website but if you think colosan is good as well then maybe i will try that since it seems to be cheaper. Anything is better than those awful shakes I had to drink with blessed herbs...although, they have a good program, those shakes. yucky. Also, did you go on a special diet with the colosan or Oxypowder ? No fasting? Thanks and have a good day.
