Lean System 7 is a weight loss product manufactured by iSatori. It contains seven fat-burning herbal ingredients: Yerba Mate, Citrus Aurantium (bitter orange), Guarana, Forskohlii, Dandelion Leaf, Bioperien, and 7-Keto. The latter, as I have recently learned, is rather controversial, and the Canadian version of Lean system 7 does not have it.
I did some research prior to trying this product, and I liked the fact that its formula was never built around ephedra. When ephedra was banned, many ephedra-based weight loss products had to be re-formulated. With the key ingredient taken out, many of them would not be so effective. Lean system 7 never included ephedra and never relied on it. I also liked that Lean System 7 was backed by some credible studies.
The product comes in pills, they are to be taken with water 30 minutes before meals or exercising. When I took these pills before working out, I could see that my workouts were much more effectve: even just walking on a treadmill would make sweat stream down my face and neck. I did not experience any side effects, and I did lose some weight, even though I did not finish the recommended course.
Overall, I was pleased with Lean System 7 and I planned to use it again some time in the future; however, I have since found some other good ways to keep my weight in check, plus I have learned that 7-Keto may not be so safe, so I don't think I will buy this product.
