around 2011 or 2012 I saw this movie on dvd
one scene had a guy in a dark jumpsuit going into a brothel or sex club and an old lady behind the counter ignores him while reading a magazine and says to the guy about the prices of whatever
he then pulls out a silenced pistol and shoots her
he then goes into every room and shoots the occupants inside

another scene is the same guy in a room with these other guys, a second guy steals the first guy's whiskey and they start fighting, a third guy shows up, the leader of the group, the fight stops and the second guy is on the ground defeated and the third guy kills him

no idea what the movie was about, steroids that turn people into cold blooded killers? no idea
