T3 and side effects

I have been taking T3 for a few weeks increasing my dosage gradually to 20mcg. Not long after taking it I started with a rash on my chest, not too bad but now it's worse, dry and a litte itchy and has spread slightly further down my chest and there are patches on the inside of my right arm. Has anyone else experienced anything like this?

What were thyroid and vitamin levels before adding T3

Are you usually on lactose free levothyroxine

Which brand of T3 have you got

Bloods should be retested 6-8 weeks after being on constant unchanging dose and brand of levothyroxine and T3

Test early morning, ideally around 9am and last dose levothyroxine 24 hours before test

Day before test split T3 into 3 smaller doses spread through the day and last dose approx 8-12 hours before test

What vitamin supplements are you currently taking

I had a skin rash when I started taking Sigma liothyronine. Itchy red lumps. It was all over my torso. As soon as I changed brand it went away. Obviously a reaction from an ingredient in that brand. I’m much better on Thybon.
