Protein Intake.

Whey protein isolate is simply isolated from other components of whey. It isn't pre-digested. Hydrolyzed whey is usually concentrated whey subjected to acid hydrolysis, breaking it into amino acids and short peptides.

So some labels are misleading rofl. but ...
breaking it into amino acids and short peptides

isn't this what digestion does?

Yes, but by pre-digesting it, the body can absorb the amino acids almost as fast as it can absorb sugar. This has its advantages and disadvantages.

For some reason glutamine is more dense than any other powder I have tasted, not considering stuff (legal) I've dealt with in the lab. Just use the scoop that is included with the protein.

I will try full scopes. I've been doing half for about two months or so.

So my point was partially right, isolate is kinda partially pre-digested, and this is why we can absorb it so fast.

But I know fast isn't necessarily meaning good... gotta know when to use it :)

Isolate is not pre-digested at all. Maybe I wasn't clear enough: Whey protein isolate is whey which has had most of the fat, lactose, and other non-protein components removed. Hence, whey protein isolate. The peptide chains are still fully intact.

Hydrolyzed whey protein is usually whey protein concentrate (still some fat and lactose remain) which is subjected to acid hydrolysis. This leaves the fat and carbs (some of it is no longer useable) but the peptide chains are mostly broken down into mono-, di-, tri-, and oligo-peptides.

The only advantage whey isolate has over whey concentrate is that most of the fat and carbs are removed. I see little advantage of this, especially at the high cost of whey isolate in comparison to concentrate. Another advantage to concentrate is that many growth factors and immune system boosting peptide sequences are left undamaged. A little fat and carbs won't hurt (unless you are lactose intolerant, then I would suggest adding lactase).
