text: what is the best supplement ? what is the best weight gain supplement to take in succession with working out ? research has proven that suppliments probably do little if any good. if you want instant weight gain, use creatine...will add about 5 pounds of water to the average person, wets the muscles and helps them heal. other than that, if you get a good diet, suppliments are pretty much a waste of your money. regardless of all the hype you see, old fashioned hard work and a good balanced diet is the only way it is going to happen. you do not want to put on fat, so stick with a good diet of meat, carbs, oils, in all, a balanced diet. there will be plenty who tell you >>>protein shakes, protein bars, etc...waste of money, period. but if it makes you feel like you are doing something, then do what ever you want. good luck
