What we are really after to optimize the effects of GH is elevated T3 but from T4 via the body's natural conversion process. Taking T3 by itself is catabolic and will shut down natural production of TSH and thereby T4 and T3 whereas GH supplementation causes an increased conversion of T4 to T3 and in this way the effects of GH can be optimized while avoiding the problems of taking T3 directly.
Why can't you find thyroxine? It's all over the internet and cheap as dirt.
