I have been taking Pure Vitargo for close to one month now and it's an excellent product. I have to contribute my new nine pound weight gain to this product. The product did everything it said it would on their website. I didn't feel bloated or tired after working out but I did feel energize. The Pure Vitargo fills my muscle bellies and I stay pump and tight for the entire day. I added CEE, Whey, , BCAA, and to the Pure Vitargo post workout drink. The product reminds me of Cell-Tech...without the 75g of sugar. The only downside is the mixing of the product because I have to use warm water to keep the product from going gelatin on me.
