Thats because some of them are loded with caffeine and glucose. So you get a big rush of glucose which your body compensates for by releasing massive dump of insulin. Its why energy drinks like red bull and stuff are terrible to drink prior to any exercise.
I don't do pre-workout sups and i really don't take my training seriously enough to want to spend th emoney on post-workout stuff. I tend to prefer stuff like bananas about 60-90 mins before i head to the gym.
