Hi @challie,
Stinging Nettle Root did not work for me at all. IMO, most of what is available does not have enough “root” in it to actually work. Boron has worked FOR ME, and I tested the results with blood work. Others here have not been successful with Boron.
My journey started exactly as you describe … High SHBG, Normal (to high) T, and Low Free T. My thread is here if you get bored. I am doing a lot of experimentation (with pellets and adjunct medications). I also did not want to start TRT, but all signs pointed in that direction.
Good Luck.
