I'm currently using it along with BULLK and I have seen big gains in a vary of fields. I have gained 5lbs in one week (but I do eat a lot of quality foods as well). I feel bigger, I look much bigger, my well-being has improved dramatically, before, I was feeling very negative about many different things for example going to work etc. but Now I constantly feel happy and positive. I have also gained strength, did 95kgs for 5 sets of 5 reps on bench two weeks ago and it felt tough, but did 100kgs this week and it felt quite easy. I would definitely recommend this product to my clients and anyone that would want to gain size.
