Yes. When I started grappling with this topic, the conventional SHBG story seemed obviously wrong to me but I didn't have the Cataceous-level understanding to back up my skepticism. I posted my thoughts and questions about SHBG, free T, and testosterone production on a popular TRT ******** group named after a YouTube channel, and the response from the moderator / TRT clinic owner was "no, this is all wrong". When I asked why it was wrong, he said he was giving a talk on the subject in Florida and I could attend the conference if I wanted to hear him speak about it.
I'm glad I made it over here before I wasted $1,000+ on travel and conference tickets.
