GF1
If its what I think it is...its the equivalent of those pro-hormones for GF1 which is found in all growing pimply stress heads (teenagers). It basically puts your body into a more anabolic state so you can grow quicker.
At least thats the theory. I've tried some of the older ones and they work as well as eating tomatoes to sure heart desise (mildly if your lucky, but its not proven!)!!! 1AD yes! 4AD yes! GF1 NO!
Unless its the actual chemical Im skeptical until I know someone who proves me wrong, or I've proven it for myself.
I'm sure somone on here knows how it works.
