Everything I have read stresses the insulin spike after the workout. All the experts' work I read indicates that the optimal thing to do is get a 2:1 or 3:1 ratio of fast acting carbs (I use 100% grape juice and/or a banana) and quickly absorbed protein (whey protein) within a half hour after intense workouts. I would say 20-30 grams whey protein and 40-60 grams fast acting carbs. I have not heard anything about growth hormone being blunted after a workout due to an insulin spike, and if it is, then the priority must be the insulin spike. Otherwise, you can kiss your greatest potential for anabolism goodbye and say hello to catabolism.
