Congrats on the work you've put into the gym and your diet, things will only look up from here
The truth is since supplements (and even illegal stimulants) aren't regulated manufacturers don't actually say how much of what goes into there products. They just slap on the name propietary blend and hide behind the excuse that its a secret formula. Kunts

People can die or injure themselves because of this negligent marketing and inability to inform the customer driven by insatiable greed.
Truth is only you will know what your stimulant tolerance is. If you have a heart condition or are breast feeding :blush: etc.. then take these ailments into consideration. If however you are a perfectly healthy individual then simply stack the two and judge for yourself if it is to strong for you or not.
