WPC is fine if you have no problems digesting it. Considering most protein powders have a WPC/WPI blend anyway, I wouldn't worry about it too much.

cheers mate. is WPC ok to take on a cut. normally i have around 4-5 shakes a dday?

I made some decent gains with just WPC + Milk. I use some isolates now (like ErgoPharm GF-PRO / I-PRO), and they for a real treat to say the least.

To sum it up ... at the end of the day, it comes down to cost and taste ...

- The pros of concentrates is there may be higher levels of various and potentially beneficial - growth factors, lipids, phospholipids, and other potentially interesting compounds.
- The cons are lower protein gram for gram than isolates, and higher levels of fat and lactose that some people may wish to avoid. Like all whey proteins, not all concentrates are created equal in their levels of the above mentioned compounds of interest.

- The pros of Ion exchange isolates is extremely low fat and lactose levels, with the highest protein levels (on a gram for gram basis).
- The cons - which outweigh the pros in my view - is the loss of important subfractions in favor of higher amounts of Beta-Lac.

- The pros of well made micro filtered isolates is a high protein content (90% or above), low lactose and fat levels, very low levels of undenatured proteins, and the retention of important subfractions in their natural ratios.
- There really are no cons per se, unless the person wants the additional compounds (e.g., higher levels of growth factors, CLA, etc.) found in a well made concentrate.

Sure, if the carb and fat content is acceptable to you ...

yeah, normally WPC doesnt have that much fat i dont think.

It should be. They have like 2 or 3 grams of carbs and fat don't they? if a WPC is throwing your macros out of wack then you probably have a terrible diet as it is. Trust me, I know a thing or two about having a horrible diet.

Yeah ... I only mention it since 4-5 shakes per day may end up being a lot - depending on how many scoops are used per shake ...

WPC.

But if you want the best of all worlds, go with MPC (Milk Protein Concentrate)

It is better than Whey Protein Concentrate/Isolate or even standalone Casein proteins.

[Insane Clown]

Isolate is "better", but the benefits of going with an isolate over a good concentrate (or a good concentrate/isolate blend) is not significant enough to matter for the price difference.

For the most part, whey is whey, and you are best off just picking whichever (respectable) brand has the best taste and cost and let someone else worry about the concentrate/isolate issue.

Here's some information on Whey Protein and processes they go through.

WHEY TO GO -

Most of you are probably familiar with the benefits of whey protein, but here is a little background.
During the '90s, whey protein powders exploded onto the supplement scene, bumping out egg protein as the most popular protein supplement. Researchers had discovered that whey protein was superior when it came to stimulating protein synthesis, the process by which muscles increase their size.
Whey protein is rich in branched-chain amino acids (BCAAs) ? leucine, isoleucine and valine ? which, particularly leucine, are essential for muscle growth because they turn on the process of protein synthesis and supply critical building blocks for muscle protein. Whey protein is also digested and absorbed by the body more easily and rapidly than just about any other protein out there. Third, whey has an exceptionally high biological value, which basically refers to how much actual protein from a food is absorbed and how much is retained in the body. Furthermore, a growing number of studies have found that whey protein may help reduce the risk of certain cancers, improve immune function, reduce blood pressure and improve athletic performance.

MILK IT OUT -

Before whey is actually whey protein powder, it's milk. There are two protein components of milk: casein and whey. Casein makes up about 80% of the protein in milk; whey makes up the other 20%. Whereas casein proteins are globular and therefore not soluble in water, whey protein is. Think of the watery stuff that sits on top of yogurt ? that's whey, and that property makes whey protein powder easy to mix into most fluids. Still with us?
Whey protein is composed of several different protein fractions that have various properties and offer distinct benefits. Beta-lactoglobulin ? the largest protein fraction of whey protein ? is rich in BCAAs. Alpha-lactalbumin is a fraction of whey that's easily digested, allowing faster absorption and uptake by the muscles. Immunoglobulins carry antibodies in the blood and help strengthen the immune system, and bovine serum albumin peptides are rich in the precursors for glutathione (one of the body's most important antioxidants). Finally, lactoferrin and lactoperoxidase have antimicrobial properties and support the immune system.

WHEY PROTEIN PROCESSING -

A by-product of cheese manufacturing, whey was actually discarded during the cheese-making process until recently. In its original form, whey is a liquid that's mostly water with only a small percent of protein. It takes several stages of processing to create whey that's nearly all protein, and the more processing, the higher the concentration of protein in the whey. Here's the breakdown of the three basic categories of whey protein:

- Whey protein concentrate (WPC) : The first filtering step that produces whey protein powder, called ultrafiltration, involves pressure to separate the protein from the fat and lactose through a porous membrane. It produces the most basic of the whey proteins, which can range from 35%?85% in its protein concentration, depending on the amount of filtering done. Most protein powders using WPC today fall in the range of 70%?80% protein. Although WPC isn't the purest protein because it's less processed, it is a high-quality protein powder that contains some carbohydrates and fats. The good news is that the limited processing of WPC leaves most of the beneficial whey protein fractions in place, and it's usually somewhat less expensive than a whey protein isolate or hydrolysate, making it a great choice if you're on a limited supplement budget. Look for a whey protein powder that lists whey protein concentrate as the first and main ingredients.

- Whey Protein Isolate (WPI) : This protein is purer than WPC because it undergoes even more processing, such as longer filtering or additional steps like ion-exchange chromatography (see "Process of Elimination"). The extra processing allows the production of a whey protein with a concentration higher than 95% protein, making it a good choice when you're dieting because it has a lower carb and fat content. WPI has a higher biological value than WPC, making it a great protein to take before and after workouts because it's so readily digested, absorbed and used by the body. Look for protein powders that list whey protein isolate as the first and main ingredient.
>> Whey Protein Hydrolysate (WPH): When WPC or WPI goes through a process known as hydrolysis, the longer protein chains are broken down into smaller protein fragments. This means the protein is sort of "predigested" and your digestive system doesn't have to work so hard to break down the proteins. This allows WPH to be digested and absorbed even faster than WPI, making it the best postworkout protein powder you can buy. But you will have to pay more. Depending on the manufacturing process, WPH can have anywhere from 3%?50% of the amino acid bonds broken during hydrolysis. Taste is a good indicator of whether the product has a higher amount of hydrolysed bonds; protein powders with smaller protein fragments tends to have a bitter flavour. Look for products that list WPI or whey peptides on the ingredients list.

MIX IT UP -

As good as whey is, other proteins like casein, soya and egg protein have additional benefits that whey protein doesn't, so many supplement companies are now offering whey mixed with other types of protein.
Casein, usually in the form of micellar casein or caseinate, is a common add-on to mixed whey products. As fast as whey is digested and absorbed, casein is slow, providing a steady supply of amino acids to the muscles for up to seven hours. This has been shown to effectively prevent muscle protein breakdown, which is just as important for muscle growth as protein synthesis.
Soya protein, in the form of either soya protein concentrate or soya protein isolate, is also typically added to many mixed-protein products. Soya is digested and absorbed as fast as whey and is rich in the amino acids arginine, glutamine and the BCAAs. It also provides antioxidant properties that improve muscle recovery following exercise.
Some mixed-protein products even add egg white protein or egg white albumin. One of the highest-quality proteins available, it's virtually devoid of carbs and fat, and is a high-sulphur amino acid containing protein, which is critical to the body's hormone-producing pathways.
Your best bet is to go with products that list some form of whey protein or casein protein first on the ingredients list. These are good products to take between meals and before bed when you need a longer supply of amino acids. Any added soya or egg white protein is a bonus.
Hydrolysised protein is ideal postworkout since it's easily digested.

Manufacturers use numerous processing methods to separate whey protein from the lactose, fat and other components found in milk. Some common methods include:

ULTRAFILTRATION : is a process that uses pressure and a porous membrane to separate the fat and lactose from the whey proteins. It employs varying degrees of pressure to force the liquid portion through a porous membrane with tiny holes that allow only water, minerals and the smaller organic molecules to pass through. The bigger protein molecules cannot pass and are collected from the membrane for further processing.

MICROFILTRATION (MF) OR CROSS-FLOW MICROFILTRATION (CFM) : is a process that further separates the whey protein from the fat and lactose through a low-temperature process using ceramic filters that still maintain the majority of beneficial whey protein fractions. This process removes the large fat globules that ultrafiltration cannot separate, achieving a fat content of less than 1%.

ION-EXCHANGE (IE) : is a method that uses ionically charged clay resins to bind with the protein and separate it from other whey constituents. Chemicals to adjust pH, such as sodium hydroxide and hydrochloric acid, are also used in the ion-exchange process. This method is often used to produce the purest form of whey protein isolate. The drawback is that some of the beneficial whey protein fractions are lost.

If you're cutting with 4-5 shakes per day, there is a problem with your overall nutritional plan.

That's what the OP's plan is ... but I would agree that a liquid diet of whey isn't optimal ...

I totally missed that post.

Bad plan, dude!!
