Hmmm. . .Never heard of that brand. A lot of the reviews for it are good, although they could be false. However, it seems to be associated with Breast Gain Plus and Breast Success, both of which are brands with low success rates. All the articles promoting this brand you're asking of seem to recommend those other two as well. I'm not sure if that's a good sign.
