Do you "Just Whey"?
Then there's a few things you need to know

stop drinking in the past

Every day when I'm drinking my whey + casein protein shake I always smile at the irony of my drink...

We are consumers based on innovation and research. We are always digging through the internet on a mission to find the NEW. We look to the scientist for a new discovery.

Have you been drinking your 100% whey protein shake after a brutal workout, thinking you are really ahead of the curve...convinced it's the holy grail of protein?

The truth is you are drinking in the past... sacrificing that time in the gym for outdated science.

I wish I could sit here and tell you that a whey + casein protein shake is NEW cutting edge science that PEScience discovered. It's not. It was discovered by numerous renouned scientists in over a dozen human trials. It's time to take the blinders off.

The supplement industry is based around innovation.
Why are you still drinking in the past?

When building lean muscle, 100% Whey is INFERIOR

PEScience athlete drinking Select Protein

If you’re a regular 100% whey protein user, read on, because there’s something you need to know. Our investigation into the science should royally piss you off. I sure was...

In our quest to build muscle, protein intake is the single most important factor. When I say intake, I don't just mean amount...I mean the type of protein too.

Reputable journals have already tested the effects of different proteins in human subjects, and the data could not be more conclusive. Whey + Casein is the superior choice.

The media tells me that whey builds muscle. And you know what? They're totally right. Studies do show that whey alone builds muscle better than other proteins. But if you look what they compare it to, the issue is clear: studies compare whey to weak products like soy-based protein, sugary drinks, and even just water. Of course whey is going to come out on top!

Nature Had it Right

It wasn't until recently that scientists finally decided to give all these 100% whey products a run for their money. And the results were shocking.

Nature had it right. When researchers at the world-renowned Mayo Clinic tested a combination of whey + casein protein, as found naturally in milk protein, they discovered that the two protein sources work together to build lean muscle.

100% whey protein in isolation only gets you so far... it can spike protein synthesis with an influx of amino acids, but quickly returns to baseline, leaving you where you started.

Enter casein, a slower-digesting protein that's typically consumed for its anti-catabolic properties as it promotes a steady release of amino acids over time. Casein actually results in more retention of ingested protein than whey!

In another published study, researchers found the combination of whey protein with casein protein resulted in a quick increase in protein synthesis along with a sustained elevation in plasma leucine levels. Plasma leucine levels are a key dictator of muscle protein synthesis, and thus, a combination of whey protein and casein protein may serve to maximize muscle protein accumulation.

Whey protein hits the bloodstream at a fast rate, but it is casein protein that has been shown to create the strongest leucine balance. It only makes sense to consume them together.

Studies have repeatedly shown that milk may be the optimal post workout drink due to the unique delivery and interplay of milk protein's components: whey protein and casein protein, together.

In fact, the research shows that even if amino acid content of a protein is held constant, milk protein augments lean muscle accrual to a greater degree than fast-digesting hydrolyzed proteins due to the unique pattern of amino acid delivery that only milk protein can provide. Nature had it right all along: milk protein is king. Did I mention that Milk Protein Isolate is the first ingredient in our SELECT Protein?

Whey and Casein UNITED

We already know that whey protein spikes muscle protein synthesis while casein protein creates an anti-catabolic trickle of amino acids, a complementary combination that should be taken at the same time. But in addition to this, whey protein and casein protein each have their own unique bioactive subfractions and growth factors which work in concert when they're taken together.

This is why I was so pissed when I saw the new research... we've been shortchanging ourselves for years. I don't just want something better than whey... I want the best.

The 2005 International Whey Conference concluded that a mixture of whey + casein is the optimal form of protein for gaining muscle mass. That's right, even at a whey conference, the researchers found that 100% whey is not the answer!

So if a synergistic whey-casein protein blend is the optimal blend for building muscle, what do you think SELECT Protein brings you? That's right: A whey-casein blend!

Milk Protein Isolate (MPI)

Milk protein is 80% casein and 20% whey, and is our favorite source of casein and the #1 ingredient of SELECT Protein.

With Milk Protein Isolate, we've trimmed down the fat and carbohydrate content from milk, leaving you with the 20/80 whey-casein protein ratio and synergistic growth factors intact. Indeed, MPI may be the single best protein source money can buy. To quote The Protein Book by Lyle McDonald, leading nutrition expert for bodybuilders and athletes:

"[R]esearch seems to suggest that consuming slower digesting proteins, or a mixture of fast and slow proteins during the post-training period may provide superior results compared to a fast protein... [M]ilk protein isolate (MPI), which contains 20% whey and 80% casein might turn out to be an ideal post-workout protein[...] By providing a rapidly available source of amino acids (from the whey) with a slower digesting source (from the casein), both protein synthesis and breakdown should be positively affected"

Ultra-Pure WPC-80
The clean whey to go

Since we know the research says that a blend of whey protein and casein protein is optimal, we found the best source of whey protein to add to our Milk Protein Isolate to bring the ratio of whey and casein to perfection.

Whey Protein Concentrate (WPC) can be composed of anywhere from 34-80% protein. We elected to go with the highest quality possible, WPC-80 for short. This not only gives you the most high-grade protein for your buck, but unlike whey protein isolate, WPC-80 actually contains intact growth factors, allowing you to maximize lean muscle growth.

You're short-changing yourself by using any other source of whey protein, period.

And trust us... if your protein doesn't list out the percentage of its whey concentrate there is a pretty good reason... it's likely the 34% garbage. Keep on chuggin'...

SELECT Protein

A Perfected Formula

So do you "just whey?" Maybe the answer has been yes for all these years, as it was for me. But it's time to give your body what it deserves. Put down that 100% whey protein shake and stop living in the past.

Using the precise ratio developed by our experts, you will finally gain the edge that all those "wheys of the past" promised. We've done the research. The ball is in your court now. You have the power to SELECT what's best...

I've been looking for a yummy vanilla protein powder for what seems like FOREVER. I can't stand the taste of strong artificial sweeteners, which pretty much rules out all vanilla protein, but after reading the reviews, I concluded it wasn't the case with this one. So I ordered it with the confidence of finally finding a good tasting protein. What a disappointment. The taste of artificial sweetener is insanely overpowering, I tried drinking it and couldn't take more than a sip, I also tried putting it on my oatmeal and unfortunately couldn't finish it, had to throw the rest out. I ordered the Snickerdoodle flavor which I'm hoping tastes better. Really disappointed. If you don't like the taste of artificial sweetener, DO NOT BUY THIS.

Pretty solid flavor, great for microwave mug cakes. Pretty smooth texture as well with a nice thickness. Not the best, but a good option.

Overall this protein is pretty solid for the price. I like that it has slow releasing protein as well as fast releasing. Snickerdoodle is my personal favorite flavor. Vanilla seemed to be the hardest to mix in a shaker bottle and would sometimes be a little too thick for my liking (I mix this with 2% milk).

I don’t know how this product is not in the top 10 Best selllers for Protein. It’s been proven time and time again that whey plus casein is far superior to whey alone and the taste of this product is amazing! Even my wife drinks it.

This is a delicious protein powder. I have mixed it into energy balls and used it as a shake mixed with just water. This is by far the best protein powder I have ever used for a simple protein shake. My only issue has been it doesn’t dissolve as well as I would like it to. Otherwise it is delicious, not too thick, and a great fast way to get in my protein.

Delicious product. Snickerdoodle is my favorite flavor by far. They all mix well. Prices are about what you'd pay for comparable products.

The chocolate frosted cupcake is just that, I feel like I am drinking a cupcake when I have it. It is a bit on the sweet side so just beware. The vanilla is to DIE for. I use it in my overnight oats and protein pancakes and it is absolutely delicious. The snickerdoodle was good but just wasn't for me. I did use it in my overnight oats and it made it taste like apple pie if I added bits of apple to it.

It was way too sweet for me. I have had this tub just laying around in my pantry because I can not get over the sweetness. I tried adding water and banana to blend it for less sweetness, but that still didn't work. I even tried mixing it with an unflavored protein mix and still can taste it. Guess it just isn't for me. Glad I tried it tho, sucks that it didn't work out for me especially seeing all these great reviews I was really excited to try it.

Wasn't a huge fan of many of the flavors, the mint one was good but overpowering. However the frosted cupcake- LAWD HAVE MERCY. Best protein hands down. This stuff mixes like buttery smooth goodness too.

Both of these protein supplements perform and taste great. The casin is a perk that other protein powders do not offer. The only semi negative thing is that the powder is SWEET. I traditionally due two scoops but there is no way I able to get that down. I've to break my shake into two servings. I take one scoop immediately following my workout then I take another scoop an hour or so later. Although I tag this as a negative I would much rather prefer the excess sweet issue compared to something that tastes horrible. As my buddy who referred me to the select brand stated, "think of this as a dessert/shake, save it for when u are craving sugar". I fully recommend this product and have ordered additional protein powder as a result of my complete satisfaction.
