Jay Campbell has many excellent podcasts on testosterone and TRT. The podcasts he did a few years ago with Cernovich led me to get tested and as a 30 year old found 480ng/dl. Under the old labcorp values thats ~17%th percentile and what I’d expect if I was in my late 50’s or 60’s. That’s less than optimal for me. Urologist said, of course, that I was too young for TRT and my values were “fine”. The anti aging clinics near me in the north east cost around $3k a year but if you are enterprising and can figure out bitcoin you can devise your own course of treatment via online sources and it might only cost say $600/year. Do your own research, learn how to use a needle, and get your bloodwork done regularly. As Mangan always tells us, you are in charge of your own health, not your doctor, and if your hormones are out of whack you need to get that fixed!
But I'm not more aggressive—a behavior change often tied to testosterone. That's not surprising to Robert Sapolsky, ., a neuroendocrinologist at Stanford University and a leading researcher on stress and behavior. "It's really not the case that testosterone 'causes' aggressive behavior," he says. "Instead, it makes the brain more sensitive to social cues that trigger aggression. And in support of that, a guy's testosterone level isn't a very good predictor of how likely he is to be aggressive."
