One has worked better than anything els for me take 1200 mg a day of l theanine along with worm wood black wallnut and clove but to be honest I think the l theanine will completly destroy any parasite in you along with brain parasites I know this will work for alot of you please take my advice the proof will be when you wake the next day with a migrain chills fever because the l theanine will have killed plenty of them if not all do not exceed 1200 mgs a day l theanine is bbb which will destroy the ones in your head. Youll get worse before you get better by the way.
