DO NOT DO THIS! Ok, I wanted to make sure everyone's careful. I blended my own T3 capsules and I miscalculated the measurement. I ran about 1500mcg/ed. I started to get shakes and started feeling really bad at about 2 1/2 weeks. By 4 weeks I was shaking, lethargic, practically couldn't get out of bed. I lost 45 lbs in 4 weeks. I looked like a skeleton. Guys, T3 is really serious stuff. It took me about 7 weeks to recover. It is AMAZING how resilient our thyroids are. Within 7 weeks my T3/T4 blood work was back to normal. My T3/T4 was literally off the charts for the first 2 blood work. The endo wanted to do emergency surgery and remove my thyroids. Whew, good thing I waited.
