I'd say consult with someone like an endocrinologist who you know for a fact treats people for testosterone deficiency. 380 isn't terrible, but this is coming from a guy who's never had a test come back over 300. I will say trying to address it through a GP turned into a farce, and when I found an endocrinologist office that I saw satisfied reviews from TRT patients I got a MUCH better consultation. They will have experience treating this, and thus will be better able to provide an opinion on what is low enough to warrant any intervention.
