I need help gaining muscle m?

i was taking muscle juice for about 3 months which really helped but as soon as i stopped taking it i lost about 5 (hard earned pounds)! i weigh about 175 pounds and I really would love to be about 185 to 190. the only other thing i am taking is no xplode to help me get energized but thats it. i need to know what is a really strong weight gaining supplement i can take to help me get that extra 10 pounds! thanks a lot
