TSH downreg?

Do thermogenics downregulate only the adrenergic receptors or do they also affect TSH pruduction? I’m referring to short-term use such as 3-4 weeks.

Unless there has been more recent research to indicate otherwise, there should NOT be down regulation. Hormones of the adreanl cortices and those of the thyroid are stimulated, regulated and interact via different pathways along the pituitary/hypothalamic axis.

In other words, thermogenics should NOT affect TSH production in any significant way…hope this helps…
