Well like hardgainer mentioned Diet is really the key in this. You could be taking top of the line thermogenics but if your diet is bad then they aren't going to do much for you at all. You mentioned strict diet do you have something that you could post breaking down the meals into micronutrients (protien/fat/carbs) and timing as well?

To answer your question though more directly, sure there are definatly some supplements that will help you out in losing weight, but my whole point is, why invest in some product thats gunna cost your prolly $30-40 if your not going to be using it to the best of your ability. Diet is the key
