Often sissy write saying that bitter and do not dissolve in water, even though, by definition, it is these properties and must have a high-quality amino acids. I zhru only these, as always prefer to use the products in their pure form, ie, powder, so it turns out cheaper, and the powder form is more confidence, and then pour in the capsule and can chalk or something empty. A dose I myself can calculate, why pay for something that you can do yourself. In general, a great product for the price.
