Hormones like testosterone and estrogen provide signals about the body's health status, which are suppressed when the body is sick.

“These are hormones that give us signals not about I mean about what's going on in our own bodies uh like are we making eggs? Are we making sperm? Are we healthy? Are we sick? You know, all of that is communicated like if you're sick, your uh those systems are suppressed and your hormone levels are going to be lower, which is adaptive and it it will help you, you know, and that won't happen if you're taking it all exogenously”
