If you feel you have proof that insulin spike PWO des anything for anabolism, then post it.
There is no proof of that being true...
Hell here's another study which states that glutamine supplementation works just as well as carbohydrates pWO to restore glycogen.
To reiterate the point. carbohydrates are not needed PWO if adequate proteins are present...
Effect of oral glutamine on whole body carbohydrate storage during recovery from exhaustive exercise -- Bowtell et al. 86 (6): 1770 -- Journal of Applied Physiology
However, when the results from the present study are directly compared with those obtained by Varnier and colleagues (36), in a study carried out in our laboratory and using an identical experimental protocol in similar subjects, oral glutamine does appear to promote net resynthesis of muscle glycogen stores relative to control subjects in whom saline or alanine+glycine were infused. We found that after the subjects' consumption of the glutamine-only drink, the rate of muscle glycogen storage was 4.1 ± 1.1 mmol · kg wet wt-1 · h-1, whereas Varnier and colleagues found that the rate of net muscle glycogen storage after infusion of either saline or alanine+glycine fell within the range 0.5-1.0 mmol · kg wet wt-1 · h-1, which is consistent with previously reported results. The effect of glutamine may be due to one or both of two possibilities: first, glutamine has been shown to be an effective substrate for hepatic glycogen synthesis in 72-h fasted rats, i.e., when glycogen is severely depleted (27); such a scenario could also occur in postexercise muscle in which glycogen is low and in which all of the required transporters and enzymes exist. In skeletal muscle, the exogenous glutamine will be rapidly taken up through system Nm (1), where it can be deaminated to form glutamate and then 2-oxoglutarate through the action of either glutaminase and glutamate dehydrogenase or glutamine transaminase and omega -amidase. It is possible, then, for the 2-oxoglutarate to enter the TCA cycle and be removed at the level of malate (by the action either of malate dehydrogenase or of the malic enzyme plus phosphoenolpyruvate carboxykinase and pyruvate kinase); the malate can be converted to oxaloacetate, phosphoenolpyruvate, and finally pyruvate, which may then be used in the glycogenic pathway by reversal of glycolysis to fructose 1,6-bisphosphate. This pathway may be particularly active at the end of exercise, when both the availability of glycogenic metabolites and muscle glycogen concentration are low; comparisons may be drawn to the physiological state in the starved condition, when glutamine has proved to be an effective glycogenic substrate in rat muscle (27). However, only 55 mmol of glutamine were ingested, of which, at most, probably only 47% reached the systemic circulation (15); thus the resultant glycogenic precursor would be of minor importance relative to the 119 mmol of muscle glycogen storage that occurred during the 2-h recovery period.

In conclusion, ingestion of glutamine alone appeared to promote muscle glycogen resynthesis during recovery from exhaustive exercise, relative to that expected from studies in which no substrate was provided. The promotion of muscle glycogen synthesis by consumption of glucose polymer and of glutamine was not additive.
However, the addition of glutamine to the glucose polymer drink resulted in a greater storage of carbohydrate in sites other than skeletal muscle, the most likely candidate being the liver.
