"In August, Mr. Emmanuel Mutisya, a Kenyan with United Nations University, will accompany AquaLiv representatives to Kenya and aid in the identification of clinics capable of carrying out the clinical trials. "Earlier this year, Mr. Mutisya supplied 10 Kenyans with our NatuRx™ HIV/AIDS treatment. Since then, they stopped taking their costly antiretroviral drugs and their condition has improved. Mr. Mutisya is now a believer in AquaLiv technology," added Mr. Hoffman."
