We had a conversation about this earlier, so I figured I would update those involved, and broadcast to all the silent but interested observers.
The question: what effect do anabolic steroids have on the thyroid horomone level of someone on full replacement (hypothyroidism)? Does it interfere with or change required dose, etc.?
The answer: None. (atleast for me)
I had my thyroid checked routinely before cycle and once again in the last half of cycle and there has been no change. I have been on a steady synthroid dose of 137 mcg the entire time.
Cycle info: 400mg test E weekly, 0.25 mg adex EOD, 500 IU HCG weekly.
For me, none of these drugs are interfering with my synthroid therapy.
It's a sample size of one, so take this for what it's worth. But, given the lack of info out there on this, I thought I should share my experience with the community.
