I think just like any other substance in bodybuilding it has its place.....especially for those who compete...But thats just my opinion....I don't think that any of us are in a position to judge others for using it...
To each their own i tried it briefly it worked ,but I only used 1 bottle increased bis around an inch, which is dramatic I used the zoelabs one with out colagen,I feel its as safe as anything you just have to aspirate and dont go overboard like that idiot Greg Valentino.
