The two most effective cutting supplements out currently in my opinion are:
Recreate - This is an elite fat burner which burns fat 23 different ways, regulates cortisol, and also helps to promote clean eating. Recreate is completely unique because it contains revolutionary and new ingredients, including Cir20x which stimulates lipolysis 20 times greater than caffeine.
Anabolic Pump - Obviously when you`re on a cut, you want to lose as much fat as possible with keeping as much strength and muscle mass as possible. This is where Anabolic Pump comes in; it will help you to lose fat by inhibiting glucose uptake in fat cells and it also helps to release more fatty acids into the blood stream to be oxidized. It helps you to gain muscle because it super saturates your muscles with glucose and amino acids and this causes protein synthesis due to the increased cell volumization.
Search the forums for reviews on these two products. You will see that they get a lot of good feedback.
