there will be a lot of changing of train of thought dealing with peptopro... not all protein powders are equal. just because you take in 50g of a said protein does not mean your body uses 50g. peptopro, is a different story. think of it like this, a serving of pepto pro, is 5-10g, which is the same as a 70cc scoop or 25-30g of a other proteins, even the loved WPI. as you can see the expense starts to become clear as it is much more potent. i would not recommend using more than 10g per sitting either, i have gone as high as 30-50g per sitting and it gives a pretty good headache everytime.
we are currently coming up with some doseing protocals as many are so stuck on using protein powders to complete their "daily amount of protein cals", this is not used for that.

Here is the verbage PeptoPro uses to describe the effects, though Hydrolyzed Caseins are casein products, any Hydrolyzed product is in a class of its own, and will not follow the general rules of any concentrates, isolates, or caseins:
A recovery drink with fast peptides which is clear, stable and delicious?! Until recently, an impossibility. But now there is PeptoPro®, the ready-to-use DSM solution for your recovery drinks.
Protein drinks
Carbohydrates and fats are the only fuel the body needs. On the other hand, proteins supply energy and the building blocks for e.g. muscles, tissue and cell membranes. That is why they are used so much by sportspeople. Up to now they have had to content themselves with an unpalatable suspension of protein powder in water.
To make protein clearly water soluble, it has to be hydrolysed. The resulting peptides are, however, often extremely bitter. Also, solutions of amino acids are no option because they are very reactive and unstable in solution and in addition are forbidden in the EU.
Natural food protein is too big to be absorbed by the human gut. Our body has to digest the protein by breaking it down into smaller pieces which can be absorbed. Only single amino acids, and di- and tri-peptides can be directly absorbed in our intestinal tract via specific peptide importers. PeptoPro® contains 70-80% small di- and tri-peptides which are directly absorbed with digestion.
Di- and tripeptides
With its patented technology PeptoPro® is very rich in small di- and tri-peptides. These score better on all fronts:
very easily soluble in water
stable, even in an acidic environment
no bitter taste
hypoallergenic
permitted in all countries
fast and total absorption by the body
stimulates the release of insulin
New class
PeptoPro® ushers in a new drinks category onto the sports drinks and soft drinks market. Normal sports drinks covered only three of the four elements: water for rehydration, glucose and/or electrolytes. PeptoPro® now finally adds protein in dissolvable form. Active peptides, which together with carbohydrates raise the concentration of insulin and supply the building blocks required for muscle recovery. The result: faster muscle refuelling and energy recovery.
Comparison of protein sources
Proteins can be obtained from food such as meat and fish, soya, wheat, peas, potatoes and rice. 80% of the milk protein consists of casein, which settles when the milk is acidified. The remaining liquid contains whey proteins, which are water soluble (but not clear).
Here are the different sources of protein supplements with their advantages and drawbacks:
Whey protein. Milk proteins like whey or casein sometimes cause cow-milk allergies, and whey protein in higher doses can lead to digestive problems like flatulence and diarrhoea. The solution of whey protein in water is not clear unless the big proteins have been strained off or partially hydrolysed. Some people have problems in digesting complete whey protein.
Intact proteins are not easily digested and are therefore not usable during or before sports activities. Also, they do not increase the insulin level during the recovery phase.
Amino acids did not obtain GRAS classification (Generally Recognised As Safe) in the US and are not allowed for use in food production in Europe. They are unstable in drinks and react with sugar (so-called Maillard reaction). And finally, they raise the osmolality of the drinks, which leads to poorer sugar, water and mineral absorption.
Peptides obtained by ‘classic’ hydrolysis are extremely bitter, are absorbed slower, and can cause some allergic reactions and have no or only a low effect on raising the insulin level after exercise
The di- and tripeptides in PeptoPro® are completely water soluble. They form a clear and stable solution, which is not bitter. They are quickly absorbed by the body and stimulate insulin production. They are hypoallergenic, and were thoroughly tested during the Athens Olympic Games in 2004.
like earlier stated, there is much work to be done on our end in teaching everyone that this protein powder should not be used as if it were like any other protein powder...
i see you guys saying 100g a day, are you kidding me. i wouldn't recommend using more than 5-10g pre-workout, 5-10g during and then maybe 5-10g PWO, and then your normal PWO meal. peptopro should not be used as a protein you would use to get your daily caloric protein levels in, not even close.
if you are comparing it to other protein powders, sure it is expensive, but it isn't comparable, and shouldn't be compared. so you are not comparing apples to apples.

another thing as well, i see everyone saying it's a casein, doesn't it defeat the purpose being a casein. we need to start thinking out of the box on this material. i see people asking all the time, so is this hydrolzyed product a concentrate or a isolate, etc... there is no real answer to that question as some materials regardless of what the industry has told you (whey is fast, and casein is slow, etc.), is not catagorized like that.
doug
yep you hit it. i think it is the industries doing... we as a whole push ideals so far and passionately it almost becomes common knowledge and set in stone, but the problem is, science is ever changing and much of the full story is never fully told. like the concept of caseins being slow absorbing and that's it. the problem is that is 5% of it, it goes way beyond that and that statement can be 100% incorrect in some instances.
i guess it is our job to properly inform, but i will say sometimes when we try to inform we get the backlash. just like what happened with waxy maize starch, when we first launched it a year or 2 back or CEE for that matter. everyone was so stuck on the dextrose/maltodextrin train or crea-mono, we would almost get 20 emails a day with people trying to prove us wrong of why malt/dex was better than a starch, and they were passionately angry about it, hell some still are. but know that tide has turned and most are using wms now. i guess sometimes those wheels take a bit of greasing to get the thought process moving in the other direction.
and the funny thing is, i know in about 6-12 months, when a whole new scope of creatines come out we will have to do it again. and everyone is going to say CEE is the best and we will have to then discuss why CEE is now obsolete.
more to come...
