Check out the label...
4-HI, the main ingredient, is an extremely promising insulin potentiator. But the studies used 1.5 grams of HI and Phosphagen XT only has 600mg per serving. So you could double your serving size to achieve that amount almost, but then you'd be consuming 340 calories, 20 gr creatine, 81 gr of carbs, and 78 gr of sugar! Not to mention, it would only last you 9 days... sounds like another EAS rip off to me.
