It is an ECA stack -- the onyl difference is the proper ration of nutrients is already calculated for you. It is much cheaper to buy ephedrine, caffeine, and asparin separately -- however, then you have to set out the right amount yourself. If used properly, I think they can be very effective and safe. Make sure cycle on/off of whatever thermogenic you use -- otherwise you risk hurting the functioning of your adrenal gland.
