i've been working out for about 6 months now, and i see some definition at various muscle areas, but i have not gained any weight i've always not been a person who eats alot nd am regularly missing meals and eating lots of fast food i think this may be a big part of the problem, but i would also like to drink some sort of protein shake my goal is to basically put on some muscle mass, so which protein powder should i buy??
thanks in advance
