THIS IS NOT A FLAME ON UNDERGROUND OR HOMEMADE GEAR!
I have neve used it and I recently had some gyno removed and I will just never mess with it. Most people use underground because it is cheaper. Money is not a problem for me so I will use the real stuff. I have a few friends tht use **'s gear and have had little if any gains. This is just my 2 cents and should not be taken as undisputed facts!
