I finally added t4 after running 4iu/day of hgh for a month now. I have a pretty high metabolism already and get hot easily, so I wasn't totally convinced that the hgh was suppressing my thyroid much. So I started with 500mcg/day and now im doing around 300mcg. I get hot soooo easily now, and my palms, ass, etc sweat! My ac in my house is usually at around 74, but now I have to keep it at 70 to feel comfortable. Maybe I should ditch the t4?
