Glutamine dosing while on precontest diet

I know its a bit late in the day being less then 5 weeks out and all, but i just got my order of glutamine. (Bananna flvour-yum). Anyway i'm not sure how much i should be taking a day.
I was thinking 10g with meal 1
10g before teh gym (on training days)
10g after the gym
10g before bed.
Is 40g too much
and is 20g enough on non training days or is that still too much?

L-glutamine is Useless it is terminated by the gut

( though personally I see use for it as fuel for the gut)

EnerG glutamine Peptides or Sans NAG seem to deliver glutamine to the muscle

oh and take about 50 grams of the Glutamine Peptides each day

either in 2 serving or in one pop
