You can use one or all of the Beck units. Keep in mind, the three units support and complement each other; this was how Bob planned it. For example, micropulsing with the blood electrifier, since it cleans the blood that circulates throughout the body, has the most overall effect. He included drinking colloidal silver which targets the digestive system and internal processes by acting as a second coat of armor and so assisting the immune system by reducing the number of harmful
microbes.
Bob then realized there was a need for something to address the lymph, non-blood systems and other harder-to-reach places, so he invented the magnetic pulser. Next, he recognized the need to flush out the toxins released by micropulsing and magnetic pulsing - and came up with a unit that ozonated drinking water. All three units work hand-in-hand in supporting the body to heal itself.
The Beck units also function independently, so if budget dictates or you're inclined to start with one unit, we recommend the blood electrifier/micropulsing unit. Most people start with this unit and add in other units as they can.
Whether you start with one, two, or three units - the point is you are starting. You're moving forward and taking your power back. Even more, you're giving your body the tools it needs to heal and attain the state of health you're meant to have.
