Side by side comparison of ON's Performance Whey (left), vs the new Performance Whey 100% Isolate (right): http://i.imgur.com/DJuxY.jpg
(100% Gold standard is a mix of concentrate and isolate.)
This is for pure isolate only.

"Protein isolates. This is the next step up in purification from simple whey concentrates; the protein is purified again using more filtration or a technique called ion-exchange or cross-flow microfiltration. Protein isolates have very low levels of carbohydrates and fat and are almost exclusively pure protein. People with lactose intolerance usually don’t have trouble with whey protein isolates. Many companies that make whey protein isolates certify that their product is lactose free or they will even add lactase which is an enzyme that breaks down lactose to the protein powder to help with digestion.

proteins found in Isolates are broken down into smaller pieces to allow it to get in your system more rapidly with the belief it will help enable your muscles to start rebuilding quicker.
The primary difference between isolate and concentrate is that the isolate is the most purest form of protein. Whey isolate usually contains between 90-94% protein while whey concentrate has a protein ratio of around 70-85%. "

Everything in the OP is on point except for this "proteins found in Isolates are broken down into smaller pieces to allow it to get in your system more rapidly with the belief it will help enable your muscles to start rebuilding quicker."

That is crap.

You will not see better results using concentrate vs isolate. Due to the higher cost it's generally not advisable to use pure isolate protein unless you are lactose intolerant. Likewise, it's not advisable to use a bargain protein powder like ON Performance Whey (concentrate version) because it has so much crap in it.

If you aren't lactose intolerant use a good whey concentrate or blend and you'll be good to go. In fact a blend is arguably better than pure isolate any time other than breakfast.

That being said, this looks like a pretty good deal for isolate. If the price is good there certainly is no harm to buying isolate. I just want to debunk the myth that you'll get better results with isolate. Fortunately, that myth seems to be on its last legs. Several years ago people would insist that isolate had magical properties that concentrate didn't have Wink

PPG = 2.7 cents after tax in Chicago.

i thought that isolate has a higher biological value than concentrate?

Is there a particular reason why isolate is better during breakfast?

Is vanilla flavor not so sweet? Are there any not so sweet tasting protein powder? At the top of the attached picture, the other cookies and cream brand is so sweet that it is hard to drink.

The Isolate is particularly useful in the morning time as it will be available more quickly as you end your sleep fast.

Vanilla is not too sweet, it reminds me of angel food cake. The cookies n Cream from MP is far sweeter, I like both brands to be honest. I find that my smoothies come out extra creamy with this powder. Mixes extremely well in water or almond milk (my favorite).

I mix a scoop of Amazing Grass Superfoods into the blender bottle with this ON isolate and it creates what I like to think of my Incredible Hulk Drink Wink Its great post workout or breakfast time.

At breakfast, you've likely been fasting for 8-12 hours, which is enough time for your amino acid circulation to actually drop off.

Once you've eaten and you're in the post-prandial ("fed") state, amino acid circulation is going to stay pretty steady assuming your overall intake is good. Your digestive system has feedback mechanisms that actually turn it into a "protein buffer" for continuous release. Not making this stuff up--check out the Examine.com article on how much protein you can eat in one sitting [examine.com] for readable discussion of the science around it.

The practical consequence of this is that "fast-digesting" proteins like isolates won't really do anything extra to benefit you unless you're already fasted, since your "buffer" is already primed. Some prominent figures in the field like Alan Aragon have even chimed in that the anti-catabolic effects of "slow" digesting proteins like casein can actually outweigh any anabolic benefits of "fast" digesting proteins anyhow.

In the end, for nearly all practical applications, a protein blend with variable digestion rates is the more versatile and useful option. Avoiding fillers and taurine/glycine padding is still great advice, but unless you have special dietary needs (e.g. lactose intolerance), there's very little special about isolates unless you just want to throw money at the problem needlessly.

I don't see why anyone would buy this over Gold Standard which has been the benchmark for years, $39.99 + tax depending on where you are makes it more expensive than ON Gold Standard through most of the recent deals.

Bigger scoop = less servings per tub, smaller tub 4.3-4.5lb, more fat, more carbs, less protein. Don't let Costco fool just just cause it's "regularly" $50 and now on sale. 24 Hour, LA Fitness, GNC, Vitamin Shoppe, etc. all love using the "MSRP" for products and marking them down to internet prices to try to nab the less tech savvy crowd, if you're on SD this should be a no brainer.

Whey Isolate is much too slow-absorbing for my needs. I take protein molecules intravenously post-workout.

Approximately 75 % of Earths population is lactose intolerant... Soooo it seems you are in the minority that sees little benefit to isolates over concentrates.. Besides the nutrition profile is far superior, with far less fat (1g vs. 4g), cholesterol (1g vs. 4g.) and less calories. It even has a smaller serving size, yielding more servings per container (55 vs. 50servings)

even tho the serving size is smaller, is the actual scoop smaller?

Wont be $39.99 haven't seen it that low in years, used to be $35/5lb tub but those days are long gone, here's the latest FP SD for ON Gold Standard, dead now but $42.75 shipped, no tax in most states.

http://slickdeals.net/permadeal/112472/drugstore.com---5lb-optimum-nutrition-100-whey-protein-gold-standard-various-flavors

$39.99 + tax (San Diego 8%) puts you at $43.19 for less quantity of a lower quality product.

Serving size is by weight, depending on density of the powders in the product, the scoops may be the same but the weight of "one-scoop" may not be the same. The most accurate way would be to weigh it out on a scale. The ON Gold Standard 70cc scoop level is not one serving 30.4g so they put "one rounded scoop" on the label.

The vast majority of Earth's illustrious population can handle a few grams of incidental lactose in a concentrate product. If you experience discomfort, then sure, but I wouldn't naively assume that you can't digest it, either.

The "performance whey" blend definitely has an inferior profile to the isolate if you're looking for straight protein, I won't argue that; but I would argue that most people already conscientious enough to be using protein supplements are exceeding their protein needs while perhaps neglecting other important minimums on their dietary fat. It's also doubly ironic if someone spends a bunch of money on an isolate only to promptly blend it in milk.

And yes, of course the isolate has a smaller serving size. Under any normal conditions, however, those servings are much more expensive.
