Steroids:

Yuniesky Betancourt doesn’t do ’em! This is according to the Mitchell Report, which says that these guys, including Glenallen Hill and FP Santangelo, did take steroids.
Of course, the Mitchell Report isn’t close to exhaustive (it pretty much just covers the Bay Area and New York), but it’s nice to know that this Rikimbili may not be supercharged with the drugs.
