Bullet Proof just got back in stock at our warehouses yesterday so it should be at our retailers soon. Based off of the description of your goals, I think you may be better off stacking Shred Matrix and Battle Fuel. You can certainly add the BP and Assault in there as well but the Shred should be the cornerstone of a stack to lean you out. Let me know what your BF% is around, your training and what type of diet you use and I can help you come up with the perfect stack.
As for the Battle Fuel, I know MrChristian on here has used it as well as a few others so you may want to PM him for a review. I have probably used Battle Fuel more than any one else out there lol I can tell you its one of my favorite supplements for strength. I am currently experimenting with using two packs a day, but in all honestly it doesn't seem to have many advantages over 1 pack. You can also PM me if you have any other questions.
