The guys today have more access to stims and diuretics and they're still blobs. There comes a point where you're simply "overstuffed." You can only carry so much mass on any particular frame. The problem is, too many people want the short cut to more size -- and they get it. At the expense of quality muscle.
Larry Scott tells of the first time he bought a new drug he'd heard of called dianabal. He said the guy who sold it to him was huge, but looked "funny." Kinda puffy and inflated. That's because back then, guys only knew size from natural training. Of course, once you have that, the drugs will send you onto the next level. But whenever the drug growth exceeds the "real" growth, that's what you get. Stuffed muscles that don't flex.
some people would suggest pinning into your bis so the oil stretches the muscle facia--i do it--not sure if it works but it looks cool for about a day but i have 36" arms....combined (sounds better that way)
