I went to the website and saw what the reviews for this product had to say. I can say that from looking at the reviews, I wouldn't be one of the partakers of this product. This brand of lipo-6 black is chocked full of caffeine and can really give you the jitters. There are people who have taken the earlier version and have had good reactions. This new version, seems to be even stronger than the last. Once again be sure to check with your doctor about this product.
