Advice on Dieting when using T3 - Thanks

I ahve used T3 before but i am going to be starting another cycle again soon for 8 weeks as Wrongun suggests. My training at the moment consists mainly of running, swimming and one day a week cirucit training. I am not overly bothered about keeping muscle mass etc as currently dont have a great deal, more into fitness training etc. I previously did a 500 calorie deficit diet however I was wondering what to do this time:-

1.) Maintenance Calories - 60% Carbs, 25% Protein and 15% Fat
2.) 500 Calorie Deficit - 60% Carbs, 25% Protein and 15% Fat

Do I need to increase any specific macronutrients i.e. carbs etc? I have read T3 can take some muscle mass I know some people will suggest higher protein intake but currentl doing 10 Mile+ runs so prefer carb intake.

Thankyou          

Sorry forgot to ask, does anyone know if its safe to take T3 with the end of a penicillin course?

I don't see a problem with penecillin use but if it were me I'd wait anyway. Going potentially catabolic while you are just recovering from infection is not ideal.

Please DO NOT pm me with questions that can be legitimately asked on the board.
