as a matter of fact, I am meso/endo. I didnt know bodytype made a difference. Why is that? Carb sensitivity?
And, how much is enough when you weigh 212 lbs? Should I add any type of high glycemic stuff when adding mass?
Personally - I am not altogether against the use of higher GI PWO in endo/meso's...
For those who are very overweight - yes - using lots of high GI carbs is not a good idea (and it is for the reason of insulin resistance issues)... And for those who have KNOWN insulin resistance/carb sensitivity issues - then yes - using lots of high GI carbs is not beneficial...
But in those who are not overweight some higher GI things PWO would be ok. So I would keep some higher GI/insulin stimulating foods, especially if you are trying to add mass.
It is just a matter of finding what each person is comfortable with and what works for that person. And at the end of the day (in the absence of complicating issues) it is the big things like your overall calorie intake, your protein intake, your essential fat intake and the effectiveness of your training program that will count.
In regards to what you could use - I am a fan of combining the following in any number of combinations:
Fat-free milk
fruit (things like grapes, banana, berries, pineapple, dates)
Thinly ground oats
Dextrose powder/lollies (if you wish)
You could use white-rice or a plain bagel (not too sure about the poptart

) if you wanted... But I like more nutrient dense foods like the above suggestions.
As for how much - Generally, for those who are not overweight, you want:
0.5g carbs/pound + 0.2-0.25g protein/pound in your PWO shake.
Which would mean ~ 106g carbs and ~42-53g protein
You could also base it on lean mass if you wanted, so if you had a BF% of ~12 you want ~93g carbs and 37-46g protein
If you are cutting then a lower figure (less ideal) you could aim for:
0.33g carbs/pound and 0.175-0.2g protein/pound
And this would be ~70g carbs and ~40g protein
