Take Heed in The Warnings
I was asked to review this product for one for my students. I teach a college program designed at creating Health and Fitness Professionals. Anytime you have a product that is affecting your Thyroid Gland, your energy systems and your cardiovascular system you need to me careful. Will it give you energy, for sure but at what risk. When a company gives a warning that it may give you high and/or low blood pressure it is telling you that is is messing around with your nervous system and if that is the case I would stay away. As well if you are being told to go off it after 12 weeks well that tells you that there are possible long term affects.
P.S. I only rated it 1 because it requires me to give it a rating.
