Well yeah.... literally anything can be a performance enhancer... theres a huge difference between that and popping for roids.
twice tested positive for drostanolone metabolites ahead of his UFC 183 fight against Diaz -- first in a Jan. 9 out-of-competition blood test, then in a Jan. 31 fight night urine screening. Silva also tested positive for a second anabolic steroid, androstane, in the Jan. 9 test, along with temazepam and oxazepam, two benzodiazepines which are banned for in-competition use by the NAC without a therapeutic use exemption.
Followed by turning up positive for synthetic testosterone and a banned diuretic in a sample collected in October 2017.
99% of the fighters aren't taking that ..... try again.
