I am very satisfied with this product. It has been for me the only thing that has helped me getting results. Even with protein shakes it did not have the same results as this. I have a skinny body type and for me is always hard to gain weight by just eating. Of course, to get results in the gym it all has to start with diet, the way we do exercises and many other specific details that at the end of the days counts for positive results.In conclusion I really recommend this supplement!
