For me:
Cutting = lower kcal/carb diet (anabolic/NHE diet), more cardio, and added EC, yohimbine hcl, and yohimburn.
Building muscle = clean diet but more kcals (still limited carbs); limited cardio.
Other than that, lifting and supplementation stays the same - lift as heavy as possible (2-6 rep range), and supplement daily multi, calcium, magnesium, potassium, glutamine, creatine, and sometimes glucosamine if the joints are bugging me.
