Exogenous Testosterone and Thyroid Function ?

[Freestyle Child]

Can anybody and the educated board members shed some light on the effects of high doses of testosterone (lets say 500mg/wk) and it's effects on thyroid function.

I've heard that testosterone can reduce the effectiveness of thyroid medications (synthroid, levothyroxine, etc). Hyper and Hypothyroidism aaa users should be aware of this.

Thanks folks!

Not sure myself-had a thyroidectomy in 1993. On synthroid ever since and currently on HRT. In my case no effect on my thyroid in blood results but I will say I tend to hold more water than most. And my dose of T is low.

AAS has little to no effect on the thyroid function. It may show a lower Total T4 and T3 level if tested but the free T3 and T4 levels will remain the sme and even in some cases be elevated.
