heard of it, but I haven't tried it. It may be worth adding... I doubt it would hurt. With regard to the thyroid increasing body hair, I've experienced the same except that I'm taking iodine. So, within a month-1.5 months of taking the iodine I get hair growth on my hands and more on forearms, etc.@ChemHead are you familiar with Cordyceps at all? If so do you think it might help with PFS? I've heard it increases 5AR expression. In regards to thyroid and 5AR, I notice increase in forearm/leg hair and slight increase in chest hair when using thyroid.
