John uses it in a foot bath with epsom salts. Each foot is in a separate tub. He uses a split tub that came with the rebuilder. You have to have each foot in its own bath. He place one lead in each tub and then runs the rebuilder. You also have the option to use a conduction gel and apply the leads to the soles of the feet (One on each foot) Scroll down to the bottom of the link to see a pic of the tub. John bought his years ago for about $400 and was a good investment for him. Home | ReBuilder Medical

Be sure to get copies of all your tests and labs. You would be surprised at what gets missed or doesn't get tested at all. Glad your GP is testing your B12 and thyroid. Your B12 should be above 400 at a minimum. If you are taking any supplements with B12 in it when you got tested, then it may be artificially elevated. Blood serum is not the most effective means of assessing B12 but is a good start.
