I use 60g dex + 40 g Malto + 50g whey isolate post workout. During wourkout I sip on a shake with 20 oz H20, 15g dex and five grams whey. The shake during keeps cortisol levels down and aminos in blood stream, and the protein lowers the GI of the dextrose. If you don't have the second meal within 45 min to an hour after that shake, you will crash, and you feel like absolute shit. That second meal should, IMO, be something like a big baked potato and a couple of very lean chicken breasts, or yams instead of baked if you don't want the starch. Those carbs that you are ingesting post workout are the carbs that you are going to be using TOMORROW for your workout, i.e, carb loading the day before athletic events, or even two days before. Try as hard as possible to injest little or no fat when you have those meals that elicit an insulin spike. Anyway, my two cents, take it for what it's worth.
