growth hormones, good or bad?

hey i have a connection for a growth hormone that my buddy uses at a nursery, it sounds like a gibberelin type of hormone. he says its used for apples and pistachios so at least you can still eat the plant with it being used. im just tripping on using it and then smoking the buds, i dont wanna get sick or even die from this. what do you guys think?
btw its a foliar spray.
