If you look right through the list you see that BDs anabol was tested twice. It contained methandienone on one occasion and methyltest on the other. This would be consistent with the comments about fakes. Seems a bit much to use this to question all of BDs stuff.
Back in the late 90's and early 00's, BD was great shit. But not since about 2005-06. I wouldn't touch it now even if legit, probably weak or expired by now.
