Canadian pills are the real stuff because they have international leading pharmacies that offer the highest quality. They provide both over-the counter products and prescription medications that are licensed. Go to www.canadadrugpharmacy.com for more details.
Other English-speaking countries spell certain words differently than in the United States. I expect you know this. I think it is wise to be suspicious if business correspondence is written in an unprofessional way with common words spelled improperly.
I have dual citizenship so I know both countries very well and I can tell you that anything you get at a Canadian pharmacy will be the same quality as an American pharmacy and you have nothing to worry about :)
