Review: Great Weight Gainer, Quality Product. - I purchased this item for my father, as he was looking to gain weight. We've used this brand before, and he's liked the taste, as well as the overall feel of it, so we decided to give it a shot. This powder is easy to use and incorporate into a daily diet. It's also packed with vitamins and protein, which is a nice bonus. The quality is also excellent. It dissolved easily in a shake, and also digests well. The texture is a little rough, though balanced and not too chunky when thoroughly incorporated, and overall, it is great. At $50 for 6 pounds, it's a bit pricey, but quality doesn't come cheap. I would recommend this product.
Review: So good, worth price ! - I picked this a couple of summers ago to help keep weight on me. I tend to lose a lot of weight in the summer because I work outside a lot. This year was no exception and this stuff is absolutely amazing! It mixes up so well, I can work out with it, which helps build muscle, it helps my energy level levels., The ingredients are everything you need in a daily supply and the taste is great. I always mix mine with frozen fruit or peanut butter.!
