I buy this to get a quick shot of protein between meals, or when I don't have time to eat. I work in the medical field and this product is identical to the formula we give patients in the hospital who suffer from cachexia or muscle wasting. I won't comment on the taste because who cares? It's literally a shot. Having said that, I STRONGLY recommend the fruit punch over the blue as the blue...comes back out - that's all I'll say. Excellent product, unique on the market!
