Where to buy Niclosamide

Hi,

I am desparately looking for a place to buy niclosamide. It seems to help with this large worm in my intestines but works slowly. Plus niclosamide is safer than the other drugs. I think I may have ropeworms but the niclosamide is needed because it weakens it down in a tolerable way. I noticed some brands of niclosamide contain an ingredient called phenolphthalein which I have read can cause cancer and is actually harmful to the GI tract due to its powerful laxative effect. I just need a place where I can buy plain niclosamide 500 mg or even powder forms. Please, if anyone knows, I am desparate and my health depends on it. Much appreciated and thank you.
