I don't know if this will help but Brian Thomas from WKRC radio in Cincinnati interviewed a doctor from YourWellnessCenter.com yesterday morning. This wellness center provides IV-C.

You have to pay $99 for the first visit so they can do a medical history and blood work to make sure things will be safe for you. After that, you schedule the IV-C at our own pace. I didn't ask about the dosage or solution used because the person on the phone wasn't the doctor and didn't know.
