what is the best brand of amino acids to gain weight?

Answer 1

If you want to gain weight use "Mass-Tech" it is made by a company called Muscletech. I used to weigh about 100, i started using it in March, I am not about 150.

Answer 2

increasing amino acids would only be part of a mass gaining program. you also need to increase the amounts of high fiber carbohydrates and health fats. gaining muscle take a lot more than just increasing the protein intake. you need to start counting calories so you know how much you are actually consuming on a regular basis.
