what is the purpose taking insulin preworkout? If insulin inhibits tissue breakdown wouldn't it be counterproductive? Always thought post workout sub-Q the way to go.
Insulin is both anabolic and anticatabolic, just like AAS are. But I think you are lumping tissue breakdown into one category. Taking something that's anticatabolic may prevent muscle breakdown when dieting, not training, sick... but it doesn't prevent breakdown in an "active" sense for lack of a better word. It won't make you immune to blisters if you are wearing shoes that don't fit properly. It's like saying taking steroids, especially fast acting orals or suspension, prior to a workout is counter productive. Taking insulin prior to a workout is to "super shuttle" the nutrients you are taking while training. Again the theory is that instead of breaking down the muscles from training and then providing it the nutrients to rebuild you are providing those nutrients while the breaking down is occurring.
Fuck. I'll let Milos explain it (BTW, this is what I learned from the gh15 board for those who say there is nothing new to learn):
So here is rationale behind it. Men have about 5L of blood and women have about 4L distributed all over the body which is constantly circulating around. In a state of rest at maximum about 10 -12 % of that blood finds its way in to our skeletal muscles, as there is no real physiological demand at the time of a low physical activity period. However, when we become active, blood is sent to our working muscles… and that increased blood flow to exercising muscles (Hyperemia) can achieve an astonishing 60% increase in blood flow or more during weight training. This happens ONLY during the workout!
So as my father suggested, if I supply all the necessary anabolic nutrients in a pre-digested form (e.g; ATP, glucose, amino acids etc) into the blood stream right before training and then continue delivering more of the same nutrients during my training session whilst raising the most anabolic hormone in our body – insulin – I will create an immediate and maximal anabolic environment.
So instead of losing nutrients (protein degradation or catabolism) we are creating a greater nutritional uptake by our muscle cells (protein synthesis or anabolism) and simultaneously preventing anti-catabolism… everything we need to great the maximal results we are after. So we need to remember that we only have this opportunity during training, not before or after as blood will not be in the muscle to this extent.
