hey....
im using megamass 5000...but i dont use it so frequently. you can get it at GNC. its like take two spoons with water or milk...but make sure that u workout after it...its extra protein for ur body which is not usual for ur lever to digest. so you need more warmness in ur body...workout everyday atleast an hour or so...no matter where. i've seen changes in me...not much but yes. good diet is always needed !
