Does ” Winstrol” cause Natural Testosterone Production shutdown ?

You might have heard that ” Winstrol” does not cause Natural Testosterone Production shutdown.

Hmmm you mean apart from when just 15mg a day taken Orally for 14 days by healthy young men results in a 55 percent reduction in serum testosterone levels accompanied by reductions in ‘derived’ free testosterone, sex hormone binding globulin and LH levels;

Along with total T4 and T3 levels falling in association with a decrease in thyroxine binding globulin.
