I've tried numerous times to contact the United States food and drug administration forensic chemistry center in Cincinnati,Ohio the coordinator tells me that someone inside the manufacturer Bio-pharm inc. committed a serious federal crime when they tampered and chemically poisoned the assured tussin DM cough syrup product I purchased from a Dollar tree store,that left me seriously ill with permanent health affects,she says the police and food and drug administration office of criminal investigation agents where Bio-pharm inc is located went inside to pursue the person involved. The FDA has refused to give me the right to the positive chemical findings or give me the identity of the small dark amorphous particles and fibrous particle contaminants their analysts found inside the dark brown plastic bottle with a label stuck to it reading" assured Tussin DM cough syrup. I want this coordinator who gathered all of the chemical toxins information and proof of tampering to FDA OCI agents in Levittown,PA where this happened,so far every FDA lab that touched and tested this poisonous liquid refuses to speak to me. Why did the FDA freedom of information act office inside the FDA office of criminal investigations headquarters send me a letter telling me "we the FDA have deleted this information from me and the public, and the Detroit Michigan FDA office for the Indiana district ,where the FDA forensic chemistry center in Cincinnati,Ohio coordinator told me to call and they would share the names of the chemicals they also found inside this bottle with me,when I called the lab person there tells me she can't disclose the names of these chemicals that poisoned me and hung up the phone. I want anyone of those FDA people to tell me the truth ! I deserve to know what the *** is this UV fluorescent radioactive chemical compound is... besides the concentrated acid and fluorine,what is the luminating substance in this stuff ,that fluoresed inside my mouth inside a darkened x-Ray room that's caused internal bleeding inside my small intestines and inside my stomach and caused esophageal stricture ect. I want dollar tree inc and Bio-pharm inc to take responsibility for the damage their defected product is causing me !
