Thanks for writing in.
I think a healthy and balanced diet with the right nutrients in the right amounts will help. You should be taking 5-6 meals in a day. Your diet should have 50-55% carbohydrate
, 15-25% protein and 20-30% fat. You should also be taking 5-6 servings of fruits and vegetables daily.
While Endura Mass will help you gain weight, the side effects of this are not known.
I would suggest you focus on a healthy lifestyle and don't take any supplements since their exact composition is not known. The weight of a person is partially controlled by genetic factors. Apart from dietary modification and exercise, there is not much we can do in this regard.
Hope this helps.
