Bull Shark Testosterone or "BST" is overpowered shit in Grand Theft Auto Online used mainly by people who are shit at the game. It gives you double damage and health for 60 seconds. It also makes basically every weapon in the game 1-2 shot kill. Literally the best idea Rockstar has come up with.

GTA Online Player #2: "He is using Bull Shark Testosterone dumbass."

GTA Online Player #1: "FUCK!"
