Since this is your first post, here is my take: workout nutrition, like most aspects of diet and training, is a leap of faith. You sometimes just need to give things a go and see the results. Here would be my argument for the intra protocol: (1) there is good science that has been around for years showing intake of simple carbs and fast-acting protein during training can extend performance and may control cortisol. (2) while growth hormone and T-levels can be raised during a workout, according to the science these are quite minimal and in no way mirror the hormonal changes achieved by drugs. (3) what does glycogen depletion during a workout actually achieve? Perhaps it earns you the right to eat carbs afterwards but the pay-off seems to be at the expense of point (1), i.e. performance. I personally shunned intra-workout carbs for years but after several months on anything from 30-80g CHO per session (depending on what my activity levels are), I have noted increased performance coupled with improved recovery. I can therefore see no reason to ditch it. If there is a caveat then it is carb quality and timing, which is another topic. You need to do your homework and ensure your insulin levels don't dip pre-workout, or during, but, as I said, a good plan (and products) negate this factor.
