It would depend on BJ's conditioning (assuming he gets past this next bout). But, it always depends on BJ's conditioning, I suppose. He handled greater wrestlers than Sherk (Hughes/GSP) at 170, and 155 is a better weight for him. However, that is assuming he will win the interim title and be prepared for either fight. I will assume he won't, and would bet on Sherk.
The CSAC screwed this hard though. Sherk independently tested the joint formula from Xyience as Norris mentioned, which came back as a false positive. I believe he also passed a polygraph did he not? Whether or not he actually used steroids, the case evidence does not corroborate with that. If it does not fit, you must acquit.
I believe it tested positive for something other than Nandrolone (sp?) so it wasn't the cause of Sherk's positive.
No, but it was done to show the propensity of 'OTC' supplements to cause false positives. I think it was initially done to show the imperfection in the CSAC's methods, and how horribly unreliable they are.
