They try and make out like it is a lot stronger than it is, by claiming because it has 335 mg of ephedra sinica in it that its more powerful than ephedrine.
When in reality 335 mg ephedra sinica is equivalent 20mg ephdrine. So purchasing an ECA stack would be more beneficial.
The side effects for ECA are well known as i'm sure you're aware of them, so i won't bother to divulge.
More over from this, i wouldn't suggest using a ECA stack or any of 'fat burner pill' until you're around 10%. Getting down to 10% and even lower is hard, don't waste your money otherwise you'll let the supplement take away your sense of accomplishment!!!
