Every two scoop is packed with 24g of fast-acting protein and digestive enzymes so that you can feed your muscles any time of the day. And it has minimal fat and carbs, so you’re left with a clean, simple protein.*

Whether it’s your first time in the gym, you’re a seasoned vet or anywhere in between, think of COR-Performance Whey as the bridge between your last rep today and your first sip of pre-workout as you head out the door tomorrow. COR-Performance Whey now comes gluten free, so everyone can indulge their sweet tooth.

Think of COR-Performance Whey as an encore to your killer workout or the dessert after your favorite meal. You earned it!

The product was exactly what I've expected. The taste is incredible, I have to say that you must try it out rather than other whey protein on the market.

Decided to pick up a tub of this to try it out as it was on the "best tasting chocolate" list here on Mistake. It's hardly the worst tasting protein I've hard, but it certainly isn't anywhere near deserving of being on a "best tasting" list. It's only saving grace is that it isn't chalky. It also leaves a pretty nasty aftertaste in your mouth so be prepared to follow up with something else. Mixability in cold water in a shaker cup is average at best (lots of shaking required) and it leaves a lot of residue in the cup itself for cleanup. The powder itself has a dust-like quality that easily becomes airborne so be ready for a dusty mess if you aren't careful. Side note : my scoop (which is TINY by the way) had a long strand of plastic about to fall off of it when I initially opened the tub (I actually thought it was a hair at first) which I had to remove. It was obviously roughly cut / detached and inserted into the tub that way. Just pointing this out since had I not noticed it I could have easily ingested it, so I'd advise you all check your scoops prior to first use.

Whipped Vanilla and PB Marshmallow For reference, I dont have a sweet tooth. For reference, a S. Bucks Frap or Chai is unpalatable for me. I Ordered a host of vanilla protein powders to add to my coffee or smoothies and a fun flavor, the PB marshmellow. I opened the container to the whipped vanilla and was taken aback by the strong sweet smell. I automatically assumed Id hate it, but it was actually very creamy and just the right amount of sweet for my purposes! I added a full serving to greek yogurt, berries and a little non dairy milk and it was delicious! Win. I opened the PB Marshmallow and whoa does it smell good. Both are yummy! Top of the list out of the 4 vanillas I ordered so far!

Product is exactly as described. It mixes very well, has good ingredients, and the flavors are some of the best I have tasted in a protein!

The chocolate is possibly the best I have ever tasted. The PB Marshmallow is sort of bland tasting. If you weren't told the flavor you would probably just assume it was a Peanut butter that you added too much liquid to. The Cinnamon Swirl is not for me. Not terrible, but not nearly as tasty or refreshing as the chocolate.

This has been our go to protein for a few years now. It has a good flavor and mixes well. I need to venture out and try more flavors......but I'm a chocolate fanatic....

The packaging is nice as expected from Cellucor and the product stacks very well with C4. However the flavor I received is floating between "Interesting" and "disgusting". Mixability is good and I got it on sale but I don't think I would buy it ever again.

Holy crap these are terrible. I normally buy BSN Chocolate Cake or what ever but it wasnt on sale this time so I took the chance and got 2 of these. They mix well so thats a plus but the flavors are bland up front followed by this gag inducing after taste that I can only associate with a load of artificial sweetener. Im not sure if thats what it is but its what i think of when i taste it. I saw a lot of good reviews and honestly most of them look suspect.... so if you have a protein you already like stick with it.

Whey Flavor: 10/10 Whey Original- Strawberry Milkshake, Cookies n Cream, Chocolate Chip Cookie Dough, Peanut Butter and Marshmellow, Cinnamon Swirl, Molten Chocolate, Whipped Vanilla Sport- Chocolate, Vanilla Extra: I have extensive research on Cellucors Whey and Protein products from the original up until todays form. Whey flavor testing was superb!!! I use a serving scoop in about 12oz of milk. I am a huge fan of Cellucors Whey line and this doesn't fail me too the least. Whey mixes well with other products from Cellucor but be careful to read the ingredients because too much isn't good. Mixability: 10/10 - No issues at all, no extra flakes give it a good shake or vortex spin and you're good to go. Overall: First off thank you Cellucor for making another excellent product, Whey products work tremendously. Not even that the flavor is a great starting point as well as it tastes amazing. But we are all here for the gainz and getting the boost necessary and routines in, I give this product a thumbs up!!!

Overall this brand is ok. I have tried 4 of their flavors. The cinnamon swirl and chocolate were my first order and both pretty good. Mixes OK with water, sometimes get clogging at the top of my bottle. The next order was Whipped Vanilla and Peanut Butter Marshmallow. The Whipped Vanilla was terrible. My wife and I couldn't take it. It was a very chemical/artificial tasting vanilla frosting. The peanut butter marshmallow was OK but didn't taste like anything really. The marcos are good however.
