He publicly accused Stevenson of using Human Growth Hormone (HGH). Guillard's own pre-fight urine sample later tested positive for cocaine. The Nevada State Athletic Commission subsequently suspended Guillard for eight months and fined him $2,100.[66] Melvin attributed his drug abuse to the death of his father at age 44, from cirrhosis after a life of heavy drinking.
He later said, "I made a lot of excuses for myself because of my father's death, and I regret it now because my father left me and he always told me, 'Son, never live a regret. Never make excuses for yourself. Be a man and take responsibility for whatever you do in life.'"[67] He has said his dad was his best friend and biggest fan, and never missed watching him fight.
