This is where it should go imo.
I am using T X, and must warn you don't use more than 3 caps a day, otherwise you will feel sluggish and depressed.(well in my case) Get some good sleep as well and you'll see good results.
I don't think you need any PCT for this since this is a good "anti-drawback" formula.
Products like Dicana and Thyro tabs would require more attention on this part, but the T X you should be fine.
