sorry but lifting that much and high intensity cardio 6 TIMES A WEEK, and limiting carbs and total intake you should not only be tired but damn near a zombie.
I am not trying to flame but Help out. I would say move to at least a T-dawg level of carbs. Do yourself a favor. You could atleast raise you carbs PWO and not slow your progress, and possibly raise it.
And this. @ 7.5% losing a lb a week at this low of a BF% is not slow by anymeans. You should really be careful about losing some of that precious LBM.
What is your current total intake and protein intake like?
Also, you say you are following the steroid diet plan. just the diet or are you on some assitance of PH/PS/AAS also that will help to maintain that LBM while dieting?
Another great option would be look into a diet that employs a heavy carb reload 1 or more times a week. Something like Ud2.
I cant really go into much more without knowing your current intake and macro breakdown, except to say you may rethink the amount of cardio you are doing and up those carbs some.
Hope this helps,
