I was 56kg 2 months ago. I restart my gyming I was not able to take enough calories per day . so had to go for a supplement . I buyed this product from nutrabay at a huge discount of 6lbs. I started using it in daily basic one time in morning and another in night. I gained weight upto 70kg in 3 months. if you are not hitting gym then I recommend you not to use this product it will only gain your fat not muscles. hitting gym is very necessary. and one of the most amazing product I ever get in my life. it has changed my life a lot. now I am on the way of 80kg
