I am a fairly skinny guy. I recently joined the gym (4 months ago) and have been working out with a personal trainer. He has me following a strict workout routine and heavy protein intake diet. My question is: what is the best supplement for building muscle mass? I have been drinking two isopure protein shakes a day and I can tell a slight difference, but I want more !! I came across a pill online called "growth factor-1". I wanted to know if anyone knew anything about this pill and if it provides results without negative side effects. If you want to read the ariticle, the link is:

i've seen that before. not worth it in my opinion. if it worked as well as they say it does, believe me EVERYONE would be taking it.
