Find a drug dealer (try to find one all alone, no gangs, that just complicates things!) Then sell your coke to him after he takes it from you and you get the money, KILL HIM then take all his money and drugs, you will have more drugs you started with and more money, just keep doing this to get more gear!! (Maybe before you kill him try using the Decrease Gang Heat cheat until its down to nothing then, when your gang heat goes up after you kill him put it back down, it will protect you much more efficiently)
