I keep hearing that it's not necessary. From what I've read, spiking insulin has been a standard practice postworkout to maintain an anabolic state, as insulin is the most powerful anabolic hormone, and it sets the stage for quicker glycogen replenishment. Complete postworkout supps likeand also seem to support this.
What do you think? Any truth to the high GI carbs/insulin spike PWO not being necessary?
