I was offered the CortiSLIM Burn For Free in exchange for an honest review. When I first opened the bottle, I was not a fan. The smell took me by surprised because I am not used to "smelling" supplements. I has Vitamin C and Chromium, couple of caffeine ingrediants and other ingredients. Despite the smell, I decided to only try one pill before I worked out. The suggested serving is 2. It did give me a a little energy to get through the workout (This is a good thing), but I could not get over the smell. I am sure this is a great product for others who can stand the smell. Unfortunately, it isn't for me.
