Thanks for looking into my topic.
I'm writing a little scientific work about a certain drug. Therefore I need some authentic information about availability and prices of cough medicine compounds containing "Pseudoephedrine".
I need to know whether these compounds can be bought in drug stores, or big stores like Wal Mart or if it is only available in pharmacies.
Or if you can only get it with a prescription from a doctor.
And then I would like to know how expensive a common compound is.
You would help me very much and of course I will reference you as a source if you wish to
