Guys, does cytomel shut down your natural production of t3 in the body?
I just started taking 10 mcg daily to lower a high RT3 and incrrease a low normal t3.
Just saw a video stating that minimum dose should be 25 mcg daily as this is what the body produces naturally? They said it was like injecting testosterone and needing a dose high enough to compensate suppression of natural production.
How accurate is this?
