I'm looking for volunteers to send me urine and saliva samples before during and after doing a bowel cleanse. I'm using something called Biological Terrain Management which claims by measuring certain things such as nitrates , ammonia, Sugar levels, salts and phs from the urine and saliva it can monitor a person's state of health. I would like to use BTM to chart people's progress whilst doing Bowel Cleanses so I can see whether and how much they are effective. I can only do tests of people in the uk. These are free of charge. Please email me if you're interested.
