No, but they're good for making you thick and strong. But that's not because it "releases more testosterone". A syringe full of testosterona and trenbologna will, but not squatting or deadlifting.
Don't go nuts like some hardcore strength trainer either. You don't need to go ultra heavy. Just lift relatively heavy and with high intensity. I don't deadlift super heavy anymore and really only do rack deads. Full deads from the floor don't hit my back the way I like and I don't need to impress anyone now that I'm able to deadlift more than half my weight. Most people don't even deadlift period.
