I dunno man :)
I struggled with all this while I was lifting 250kg deadlift and benchpressing 150kgs. I went to the gym every day. I was 210 pounds 6 feet. I ate a lot of meat. I had lots of anxiety. Today I'm 180 pounds, I do long distance running, I eat much less meat and I even do yoga. Much less anxiety :)

But I do agree that testosterone is very important for mental (and physical) health, especially for men. Absolutely. But other factors as well could possibly boost testosterone. Plus other hormones are important, like LESS cortisol for instance.
