It must to some degree or everyone wouldn't be saying to take t3 when you take gh.
I started having a horrible time taking some bf off and feeling very sluggish after a gh cycle in 2005. Finally I got up off my ass and went and had a blood test and the Dr informen me that my T3 was 67 and put me on cytomel at 50mg per day and he told me I will be on for the rest of my life.
Too bad I didn't understand the importance of blood tests before starting to see if I was hypo then.......but I definatly am now!
For the last year I have been posting articles pointing to the fact that gh can make you hypo and I was told no it didn't. But now I am very sure it does.
Only 2 ways to know is to monintor your blood work before during & after or track your basal tempature.
You are right!Physicians can't prescribe T3 is the US it's not FDA approved only Sythroid/T4...
It's not an issue for me since I have a pre-existing condition.
At what dose do you think gh can effect the thyroid?
It just seems smart to get bloodwork 4 weeks in to know for sure whats going on.
I think I read that also, what do you think about ladies testing anyway after 4 weeks?I am not sure on this one. I know Gavin Kane, I believe mentioned something like that of 5 iu's a day would need a T3 stim.
