A derisive word to describe an otherwise normale male (or possibly female) whose life is preoccupied by the hormone "testosterone". Most often a young person. Usually aggressive, egotistical, and though not necessarily unintelligent, certainly simple minded.
Hence: testosterstoned, A la "stoned."

Akin to "jock", closer to "musclehead"
You are an older guy and you happen to run into an old high school girlfriend that you never treated well. You were a naturally talented athlete and so you blame it on the hormones:

You: "Julie, I'm sorry I was always such a dick to you in high school. You know I didn't mean some of those things. Hell, I was testosterstoned from sophomore year until half way through college."

A trannie who still has feminine features, but is masculine in nature due to the large amounts of testosterone supplements taken to extradite their transition.
Although people claim that gender is a social construct, they still try to biologically alter theirs by becoming testosterstoners.
