I have it and I disagree, entirely, that low SHBG is a problem. You have to work with it, it dictates a different dosing and injection schedule and takes more care to manage E...high Free T is an absolute PLUS, but with it comes Free E. Smaller more frequent injections leads to high(er) TT and high Free T and likely no use of an AI.
I think that most that complain about it simply don't know that the standard E3.5D is not compatible for them and/or lack the ability to MAKE it work FOR THEM. Absent the discussion is Thyroid, Adrenals, and so forth that have to be investigated and treated if necessary but as a singular topic, SHBG is not bad.
I'm 10X better than I was as a Low T patient, but I test (often) got with Dr Saya, and I'm doing things to make it work, and doing things to get better still.
