sorry. BUT, for anyone who doesn't know, i did the search and found this in one of the threads. but to sum it up for someone who doesn't want to read it, glutamine peptides are better.
"Here is a good cut and paste from The Protein Factory site
I will give you a good cut and paste, form the Protein Factory, as this is a very detailed, and informative explanation.
"Glutamine Peptides in Layman's Terms
To understand the differences in glutamine peptides and regular glutamine, one must first obtain the knowledge of exactly what are peptides and how they are different from free form amino acids. Peptides are amino acids broken down into their smaller more digestible form using the hydrolyzation process. Only hydrolyzation can produce the smaller peptides, superior to free form amino acids and larger peptides currently found in your whey proteins that are produced NOT using the hydrolyzation method. The supplement companies make it sound difficult because there is a small amount of peptides that occur naturally, regularly commercially produced whole-protein supplements. Unfortunately, what the don't tell you is that these are the larger peptides with a high molecular weight, which is different from smaller di and tri peptides that are produced using the hydrolyzation method.
Several studies have shown that smaller peptides are better absorbed than larger peptides and regularly manufactured protein.
1. Amino acids from peptides are more readily absorbed than free-form amino acids, thus producing a greater insulin reaction.
2. Humans fed smaller peptides compared to whole-protein foods had a greater increase in amino acid levels.
3. Hydrolysated products produce greater pharmacological effects (increasing GH and insulin response).
4. OLIGOPEPTIDES are LARGER PEPTIDES, which are absorbed much SLOWER than small tri and di peptides. Supplement companies try to use the word "oligopeptides" to fool the customer with scientific mumbo-jumbo when they're actually stabbing themselves in the back!
Thus now our customers can see, why the Protein Factory choose Glutamine peptides instead of free-form L-Glutamine. You will get a better response with glutamine peptides when compared to L-Glutamine.
How to use a glutamine peptide supplement and incorporate it into your customized protein.
Our recommendation is to use the glutamine peptides at a serving of approximately 5 grams before and after your workout. Buy it separately and mix it in a blender with your regular protein shake. Remember, any protein processed through hydrolyzation tastes bitter, so it is difficult to take by itself. If you want to add it to your regular protein so you get approximately 5 extra grams of glutamine peptides, we would have to add 100 grams of glutamine per 340 grams of any protein you choose.
For example:
If you had 17 grams of protein and add 5 grams of glutamine to that it would give you 22 grams, so multiple 17 times 20 and that equals 340 grams. Add 100 grams of glutamine to that to equal 440 grams plus flavoring to total 1 pound. Thus one would be guaranteed to get 5 grams of glutamine peptide when taking a 22 gram serving size of powder."
