So I have heard some people say that tren can have a bad effect on the thyroid by lowering it. Does anyone how much an effect it has on it. For example: if the body makes 25mcg of t3 will tren effect it and my it only produce 20mcg? 15mcg?....
I know this is a hard question to answer without bloods.
2 question: would it be best to just run 25mcg of t3 just in case it does effect the t3 levels.
Keep in mind I'm cutting hard 2100 calories at 197lbs, 8%bf, 5'8, 30yr
Thanks boys like always
