Just to also chime in, I've been researching high DHEA S as I have been suffering from really bad brain fog the last few years.
I agree with you guys that it does seem to be too high. I'm from the UK and getting help from a GP is basically non existent, let alone a blood terms for your hormones.
I'm hoping to get a fresh blood test and pay private to see an Endo as I do thing this is definitely contributing to my brainfog/fatigue.
I also have had high DHEA-S levels since I started HRT when I was 27. Brain fog was my main complaint. Even before I went on anything my initial blood test showed that I had the high DHEA-S levels. Going on HRT fixed all my low T symptoms, except brain fog. It helped make it a lot less, but it’s the only symptom I can’t fully kick
