I take Cytomel and have since the end of last year. I was up to 75 mcgs at one point but got lowered on it because I was feeling hyper symptoms.

I am now on Cytomel (50 mcgs) and Armour (30 mgs), which is 12.5 more of T3 and I am not feeling any hyper symptoms as of yet. Next week I will be adding another 15 mgs of Armour, which should put me at 45 mgs of Armour and a total 75 mcgs of T3. We'll see if my body reacts to this one.

My Dr. only treats symptoms----he has me write my pulse down every night and judges by that. So if you're not feeling any faster pulse, shakiness, etc. don't worry about it. But as soon as you feel those symptoms, back down to your last dose. This will mean you've hit your optimal dosage for your body.

I've been tinkering with this for almost a year, wish I could just find the right dosage and get on with life.
