It seems the going idea is to time your slin intake to correspond with your PWO shakes/meals to increase the anabolism PWO.

My question is, is the purpose of having the slin immediately PWO to increase the bodies ability to uptake the nutrients immediately PWO as opposed to waiting any given amount of time and losing the possible effects of the slin PWO?

When you look at the studies by (Tipton et al., 2001) and (Rasmussen et al., 2000) regarding carbohydrate and amino acid supplementation both immediately pre-workout, immediately post-workout, and 1 and 3 hours PWO. The studies show that consuming your PWO shake 1 hour after training had a higher protein synthesis than the one taken immediately after training.
Therefore if someone were to try this theory by having a pre-workout shake, train, then time their slin to coincide with their PWO shake 1-hour after training could this in effect raise the slins effectiveness as well considering our bodies response to the carb/amino supplement is naturally higher 1-hour post-workout as opposed to immediately post-workout?

Thoughts?
