I like to think in a pyramid if your adrenals are low then maybe your thyroid will be low. My TSH is high even with good T4 and T3.
I'm starting to think that DHEA is one of the biggest hormones for a man because it will convert to DHT. I see man with 280 of testosterone and with great libido and energy because they took pregnenolone and DHEA. But you need to read about it. Some need just 5mg to feel fine if the take more they don't feel anything or just an increase of E2
