Eight months ago I was about a week into a cycle of tren when I devoloped dermographism. I immediately discontinued the tren. Now I no that it was caused by my thyroid. I have an obvious gentic link to hypothyroidism (mom, sister & aunt). Afte 8 months I finally went to the Dr to find out what was wrong. He ordered blood work which came back with my TSH level at 63.8 which is 20 times the high end of the range it is supposed to be. I was on a 6 week cycle of tren about about 18 months ago and had similar skin issues just not as bad. What is more likely, the tren is what caused the thyroid issue or it just worsend (temporarily or permanantly) and exposed the underlying gentic issue that I was already exposed to? Also, could test or tren have had a lasting effect on my thyroid? In total I have done one 6 week cycle with tren and 1 week into a 2nd cycle. btw I didn't start any thyroid meds until today.
