LeanFX should be enough to make a significant change in body composition. Depending on what your goals are, and how you are planning to attack them, it could be enough, or other tactics might be necessary.
As the others have mentioned, StimX will help a bunch. Hyperdrol or MassFX could also be employed, as they provide great nutrient repartitioning, which leads to an improved body composition as well. They're not just for bulking.
Supplements aside, the best thing to do is a li'l cardio. While a the concept of HIIT-driven cardio has shown to give great results in bodyfat reduction, it's also quite taxing on the nervous system. Low intensity cardio (1) using stored bodyfat as primary substrate (2) is not taxing on the body. I recommend trying some low intensity cardio for 30-45 minutes a few days during the week, on an empty stomach.
