hey bros was wondering how the bodybuilding have teh doctor prescribe their juice for them and if human grade test(numerous tests out there) provides more of a kick then vet,underground, etc. I would think so i mean look at the pumping iron days those guys would go to the doctor ask him what they could do to gain weight and the doctor would recommend them sum anabolic steroids, they wouldnt go to mexico or ask a cheap source at gold's for sum underdosed steroid vial that was probably processed in sumones bath tub. to make a long story short my main question is....is prescribed human grade gear that good and what is the best test for building muscle mass?
