Say you take a standard dose of 10ius of slin pwo with 65g of carbs. Now the general consensus is that all 65g will be shuttled to the muscles since that is a pretty low ammount of carbs per iu.

Now, for an exagerated example lets say you take 50ius of slin pwo (don't do this) and the same 6.5g/iu of carbs for a total of 325g of carbs. Since the carb to iu ratio is quite low would all 325g of carbs be shuttled to the muscles? Wouldn't that be way to much for the muscles to handle and thus cause the remainder to be shuttled to fat? Is there a limit to the ammount of carbs the muscles can handle? So where's the line, I see Gear uses 20ius pwo?
