A few years back I used to take Arginine and Ornithine in a 2:1 ratio for increased GH, etc...Dunno if it helped, but it was pretty in vogue back then.
Uhh.........dude those horse pills are terrible for you. They burn holes in your vital organs. If I were you, or your mommy, I would get off of those. Personally I just use powder Optimum Vanilla Ice Cream
Seriously even the people who work at GNC turn customers away from that shit.
I take the powdered blends; the ones that contain EVERY SINGLE amino in an easy-to-digest form. I suggest isopure; they make a great chocolate flavor.....
Stick with Proteins that are high in BCAA's and Glutamine. Most formulations will tell you that the protein is "enriched" with both....be careful, you never know what you are getting.
Try Isolean by Scitec....it is loaded with 15g of BCAA's and 14g of Glutamine. It is the only protein/MRP that I have seen that actually tells you the exact amount of amino's per serving.
