What dose and if you are not using it, why not? I am currently not adding T4, but the literature states that it should be included with HGH. Not T3; butT4.
i don't use it. i've been on gh for over 8 months. i used it for a while and didnt like the way it made me feel. i remember dat saying it's not necessary. if i'm not mistaken, some people may go hyper and other people hypo with their thyroid. so only if your thyroid is suppressed then you should take it. hope this helps.
I know a pair of guys they used T3 now T4 with hGH, 100mcg just after they wake up, and 100mcg ,starting with 50mcg for 1 week, in the afternoon. Both tabs before hGh inj. They think it's better T4, plus magnesium/potassium citrate and selenium. They use only human grade hGH,T4 and T3.
