I wanted to gage folks success on here with taking T3 without the use of T4. I have read many contradictory opinions on this strategy. Some folks say they get heart palpitations from just T3, while others love it and don't feel good on T4. I ask because T4 keeps my TSH very l0w (below 1) but other than that gives really no noticeable effect. It can be warming at night before bed, but often i wake up with severe histamine symptoms (awful allergies) and it seems to put like 3 extra lbs of fat on me that i have never had in my life. I am close to abandoning cynoplus but wanted to get folks experiences on here before i pull the trigger.
