You MIGHT consider low dose proviron to beat down that SHBG, but man, with those numbers, I would be looking for something totally non-suppressive, like maybe boron or something similar. Peep this link at examine
https://examine.com/topics/sex-hormo...ding-globulin/ and see if anything tickles your fancy. It is a good jumping off point at least.
That said, most of us here are not looking to be natty, so if you are just going to jump on gear anyhow, the SHBG will take of itself. But really, I would not fudge with those numbers right now, other than getting SHBG down.
Edit: I see you are on the boron train already. I would try that for a bit and see if it works.
