I'm not a doctor and it always seems theres medical evidence to sugest one thing one way or another. I just base that on my sister was overweight b/c of an underactive thyroid and the doctor told her once she starts her medications she'll always have to use it b/c it would eventually cause her thyroid to quit working. My uncle told her that too who was a RN and she decided not to take it. It wasn't t3 but it was some thyroid stuff.
Ok well I had never heard that about HGH either but did and decided to check up on it
