You don't need T3.
If you clean up your diet you will lose fat from simply sitting on your ass watching TV.
T3 for you is a bad choice IMHO.
Try these simply guidelines:
1) eat 6 meals a day
2) eat lean meat AND fibrous vegetables with each meal
3) keep carbs to under 100grams a day and eat no simply sugars (except fruits).
4) keep fats at 50grams a day and of this a maximum 15 grams of saturated fats.
5) eat 300 grams of slow-digesting protein a day (no shakes, only meat/cottage cheese, etc.)
6) keep exercising, try a combination of weights and High intensity interval training.
I'm not trying to be a prick, but at a bodyfat percentage of 30 you just need to eat properly and you will lose fat CRAZY FAST.
