Basically, NO helps to increase strength, if used in conjunction w/ creatine - but more so, endurance (for longer then normal workouts) and your turnover time in recovery. 

I don't know of anyone whose had "perpetually pumped muscles" from using it, but certainly the "pumped" effect lasts a great deal longer post-workout and decreases the bodily fatigue you might start to feel later in the day.

Regardless of the all this talk about steriods use.  Lets be 100% honest.  NO women or male BB.  Would be able to get as big and as strong as they are now without them and other drug.  When you look at the nautral BB they are about 1/3 the size of a non-nautral BB.  My theory I like big and strong women-the bigger and the stronger the better acutally.  And if it takes steriods to get them like that.  They should be free and legal.   

Last April or May a 19 year old local Seaton Hill University student.  High on drugs, broke into a rent a cop Apt. at random and tried to stab him and the rent a cop was able to beat him off with his gun.  But for some reason did not shot him. 

Than he went running around the downtown area and was stop by a female police office and after her taser and peper spray did not work on him.  He beat her up and try to steal his car and was arrested by the police while doing that.  He pleaed guilt to some charges and will spend 5 to 23 months in jail. 

Than this April a 23 yaer old student from the SAME university went nuts at his house in town here and the police SWAT team shot it out with him and he was killed.

Both of these stdents was high on drugs, not steriods, they did not say what kind of drugs.  BUt what ever it was made than go nuts.  I am sure there more incidents of that type of drug use, than "roid rage" that can be documnted.

Sorry if this seems rude, but what has this got to do with it?   You might as well say that they hadn't eaten fast food any earlier than an hour before they both went beserk, which proves that fast food doesn't cause people to go on mad rampages.
