That is a propiertary blend with some stims in it - I would not use it. First of all, products with propiertary blends should be avoided, because you never really know what is there, and basically the manufacturer is showing that they have something to hide. Then using stims for fat loss is a bad idea, because the results won't be long lasting, and stims will increase cortisol - the stress hormone that is so good at eating up your muscle mass. Also, stims have lots of side effects, which is yet another reason to avoid using them in excess.
I would rather recommend using the PPAR modulators Cardarine GW and SR9009 for that purpose - they will burn fat, increase your endurance, and will not cause any side effects at all.
