Mixed martial arts legend Ken Shamrock tested positive for three illegal anabolic steroids - Norandrosterone, Noretiocholanolone and Stanozolol - after his first round armbar submission over Ross Clifton at War Gods: "Valentine's Eve Massacre," which took place at Selland Arena in Fresno, Calif., on Feb. 13, according to the California State Athletic Commission.

Shamrock has been suspended and fined $2,500 for the transgression. He has the right to appeal the finding in the future.

Both Norandrosterone and noretiocholanolone are metabolites of the anabolic steroid nandrolone. The threshold for a positive test for metabolites of nandrolone is 2.0 ng/ml.

Stanozolol is commonly referred to as Winstrol, which is a synthetic steroid derived from testosterone. Winstrol is often used in conjunction with other anabolic steroids. Many athletes and fighters have tested positive for this steroid.
