I intend to use some for my condition and here in my country i saw some bottles with some "strenght" on the them - ppm or something.
Usually how much is safe to take per day and what strenght?
is there any way i can be sure the ones in the shop is OK -i mean is properly prepared to be effective?
and another question - supposing i will use it 10 days is it possible that the bugs get used with it? and become resistant?
