I dont wanna talk down on this post cycle idea for synthetic thyroid hormones however i pretty much lived on em for 3 years from 50mcg to 100mcg. I got bloodwork about 6mo later, thyroid perfecto. I did nothing, not even the pyrimid. Maybe its not as dnagerous as ppl think. Ive been up to 150mcg peak in my life. But I run it almost year round with very few breaks and knock on wood 5-6 years later still kickin great natty t3/4 production.
