I know I said I wasn't gonna post anymore, but it just irks me when someone claims my concerns are unfounded and simply dismisses my questions without answering them. So let's see if I am, in fact, without grounds. If I am wrong - AWESOME! Then PF3 is awesome stuff and I want it - but I want to understand why I'm wrong, which no one has been able to explain to me.
I'm just going to present the references and let them do the job for me. Here's an annotated list of the first 12 references from the write-up for PF3. If there is interest in this, I'll do it with the rest as well. It summarizes what each study was and what it found.
I highly encourage any and all of you to review these yourself so that you can come to your own conclusions. The lucky thing is, most of these studies are open access, so most of you should be able to get full text, so you don't have take me at my word or live in a molecular bio lab like I pretty much do.
Just copy/paste the title of the paper you are interested into Google and you should be good to go.
Anyways, here goes:

- Promotes the use of whey, amino acids and glutamine. No mention of bio-active isolates
- Whey and amino acids promote anabolism - real shocker there, I know

- Supports the use of whole whey, no mention of bio-active isolates

- Compares whey hydrolysate, soy and casein proteins. No mention of bio-active isolates
- Whey hydrolysate induced more muscle protein synthesis than either other protein which supports the use of pre-digested proteins. Note: PF3 is not pre-digested and hydrolysis would ablate it’s anti-inflammatory effect.

- Compares performance of Gaspari’s Sizeon Max Perf against a generic product. No mention of bio-active isolates
- Sizeon performed better than the generic whey hydrolysate product, but methods section and assays are too vague to determine mechanism.
5. Cribb PJ, Williams AD, Stathis CG, Carey MF, Hayes A. Effects of whey isolate, creatine, and resistance training on muscle hypertrophy. Med Sci Sports Exerc 2007;39(2):298-307.
- Compares the use of Whey and CreMono alone and in combination and their effects on body composition, muscle strength and fiber specificity.
- Use of either or both resulted in increased strength. No mention of immunopeptide isolates.
6. Coburn JW, Housh DJ, Housh TJ et al. Effects of leucine and whey protein supplementation during eight weeks of unilateral resistance training. J Strength Cond Res 2006;20(2):284-291.
- Compares a leucine-enriched whey protein with a placebo.
- Found that two set without supps = 1 set with supps = 1 set with placebo
- Suggests that carbs could replace your aminos intra-workout!

- Finally we see some immunopeptides come into play! Uses spray-dried animal plasma and IGG concentrates as an anti-diarrhea therapy.
- Immunoglobulin’s did reduce inflammation, but there was no change in body weight between the different experimental groups

- Pigs were fed spray-dried pig plasma supplemented with carvacrol, cinnemaldehyde and capsicum
- Pigs fed the plasma instead of soy protein gained more weight per week, but were fed equivalent amounts. Both plasma diet and soy diet also included whey as well.
- Supports the superiority of an equivalent dose of plasma over extruded soy beans for anabolism. But only in 60g/kg doses!

- Compares the effects of high calorie vs low calorie formula on newborn pigs infected with a diarrhea causing virus. No in depth description of the formula diets were provided, but no mention of immunopeptide isolates, plasma isolates or anything similar was made.
- Malnutrition had no significant change on the weight gain or intestinal function or nutritional status of infected animals
10. Jiang R, Chang X, Stoll B et al. Dietary plasma protein is used more efficiently than extruded soy protein for lean tissue growth in early-weaned pigs. J Nutr 2000;130(8):2016-2019.
- Young pigs were fed either extruded soy beans or an equivalent intake of animal plasma.
- Animals fed plasma gained more weight than those fed soy.
- Supports the superiority of plasma protein over an equivalent dose of soy, as in ref 8.
11. Gleeson M, Nieman DC, Pedersen BK. Exercise, nutrition and immune function. J Sports Sci 2004;22(1):115-125.
- A review of the effects of exercise on the immune system. No mention of immunopeptide isolates. Does support the use of carbs to decrease intra-workout cortisol levels, though.
- Exercise induces immune suppression, which is rectified through proper nutrition, and the resulting inflammation is circulatory, not in the gut where PF3 has its effect.

- CHO consumption before an exhaustive cycling bout reduced neutrophil trafficking – a readout for inflammation. No mention of immunopeptide isolates.
- In other words, carbs reduced inflammation
As I said, if people find this helpful, I'd be happy to do the rest. And again, I'm not saying anything one way or the other here - I'm just gonna present the conclusions of these studies.
If, however, one reference in particular stands out to anyone, we can go into all the depth you like discussing its findings.
