Yes sir, you can use T3 on this cycle. Understand this is a very strong hormone, not to be taken lightly. If you are not seeing the result you want now though, something is off in your diet. T3 will help but if you don't nail that diet first, it will only be a bandaid. So my suggestion would be to continue to lower carbs or carbs and fats until you start seeing the progress you want, along with adding cardio. Then from there, add in just 25mcg T3 taken first thing in the AM on empty stomach. I would suggest doing this while you are pushing hard and in a calorie deficit for no longer than 8 wks. If you keep the dose low, you will be able to stop it with no taper after. If you need more help with the diet, head to the diet header of the QA and let me know what your nutrition looks like now. Getting that in order is the most important thing
