What kind of advice is that Diamond, I've never read a helpful post from you.
Glutamine is an anticatabolic nutrient and the most abundant free form amino acid in the body. In my opinion, I think you'd benefit by taking it everyday. Most gurus will tell you to take between 5-20 grams daily, preferrably on an empty stomach for absorption to help GH.
You could take glut before your workout and then administer the glut/creatine combination immediately after your workout. Next take your protein 30 min after your glut/creat ingestion. I'm assuming you're mixing your creatine with a insulin spiking ingredient, that's why I recommend taking the protein 30 min after.
It all depends on what you want to do. Just my 2 cents.... Good luck!
