a common theme runs through correspondence empty capsules or tiny doses of medication.i have recently opened capsules over 4 months 50%were empty. my pharmacy says all is ok. my gp also not interested. is this perhaps a case of corrupt quality control as in Tanaka steel or no quality control.i presume this problem is world wide how much money has been spent on duff medication. and what effect has this had on users. next month i will take this up with my local hospital.
