I'm a big fan of Primo. you're gonna get a lot of guys tellin you that it's faked a lot, and maybe it is. but nonetheless, legit primo is available and if you aren't looking to pack on 20-30lbs(and then losing 15 at the end of a cycle) and instead 10-15lbs and keep 10 or so, it's great. I prefer not to blow up with water/fat and then lose it. I'd rather gain 15, and keep 10.
