I have no idea. You could probably get a better answer by asking a doctor. My guess non of them. Doctors are like the sales rep and the pharmacies are like the head office. The pharmacies make money every time a doctor recomends a patient to try a new drug for their illness. So I don’t think that the pharmacies would restrict the doctors from selling any kind of medicine. Theirs no reason for Steven Harper to restrict Canadian doctors from teaching their patients any kind of exercise or diets. A diet may be restricted but only depending on the patient if he or she might not be able to do certain diets do to certain allergies or body types, medical problems. Their are a few medicines that the government will not allow into Canada from the United States because of the harmful side affects. Supplements, I think your safe with supplements as well. Your best bet is to talk to a physician or do some personal research.Learning about the in’s and out’s of internet marketing can be difficult unless you have a great mentor and where can that mentorship be found? If you really want to succeed online you must get yourself a copy of Commission Blueprint 2.0 created by Steven Clayton and Tim Godfrey. The tools alone are worth the cost alone. Best wishes!
