Personaly - I look at results more than "Science". Palumbo and Rea are credible. Duchaine also. SIze alone dont sell me, but it's important. Dave and Rae were not big to start. They are very big now.
Actual experience using and monitering is real deal. Not Dan Gwarty or Nick evans shit.
Use your eyes and brain is my way. Shit - Just ask Big Guys, They will most tell you wht they use.
I look at both, really.
If the science and real-world don't agree, then I look to figure out why. As for being big, usually it's in spite of (not because of) someone's knowledge about AAS.
But also, I look at what the person is doing, and who they work with. That's important, because the number of champions they produce is a far better indicator of their ability to produce results than simply looking at what they've done with themselves. The top coaches, aas-people, dieticians, etc.....and people will hate me for this...but the top people in any of thise fields don't really work in BB'ing related areas most of the time.
