I am start my gym since 5 months ago.when I started then I am so skinny .my bodyweight is just 42 kg then I bought muscleblaze mass gainer xxl 11lbs from amazon.Flavor is too goodI bought online because 80% suppliments in india are fake.When I startrd to take this my weight 42kg after one month there was no progress I was just 42.Then my gym trainer suggest me that mass gainer is just a side food if you want the better reasult of this gainer then you take a proper diet after that he suggest me a diet plan and I am takin mass gainer properlly with proper diet.After one month I check my weight is 48 kg then I am so happy.Now after using my 11lbs mass gainer my weight is 64 kg.The main thing for weight gain is carbohydrate and mb mass gainer contains 69gm carbs in one serving.So dont fear fo for it but you should take proper diet with it otherwise it will no work.I upload my some pics before using the suppliments and after 5 months.
