Yeah, i read that article, but i don't believe it stated if one should run T4 for long periods of time, we all know that you should run Gh for 6-12 months at a time. I've always ran my T3-T4 for 3-4 wks at a time, than run clen for 3-4 wks and continue to alternate that way. I'm just wondering if thats incorrect and i should just run T4 the entire time i'm on Gh?
