at 145lbs you don't need anything else other then protein, multi-vitamin, and good diet. No supplement is going to put a lot of size on you. once you get your diet right, then you can add supplements to help speed and quality of gains. But if you insist on buying something, could try things like prime, x-factor, jacked, glycer grow, green mag, ragnarok, cre-02, but i would try and get diet right first. how old are you?
