He started by taking 1drop 2x a day. He gradually increased his dosage as he could so he didn't have to experience to much nausea and diahrea. He is now taking 15drops a day after 4 months. I recommended that he cut back now after getting such good check ups to just 6drops a day. He has gained weight and is back to work. If you have question email me (see above) or message me via cure zone. Take care.
