Went to GNC to buy a diet/appetite supplement -Quadra Lean. I heard good things about the product from body builders at the gym. I'm just a normal guy looking to drop 10/15 pounds and they said this was a good supplement. Went to buy it today, and the clerk at the counter tried to get me to buy another GNC supplement that was supposedly better in her opinion. I politely told her that it was recommended by body builders and that I would buy the Quadra Lean and if it did not work, I would try her suggested GNC product. My question is, do they work on commission? Why the big push away from one product and towards another?
