Amazing! Superb!
Great taste - macros are phenomenal. This is my new favorite protein powder. I’ve tried both this flavor and the Hershey flavor and both are really great and I highly recommend!

Taste Amazing, even with just water
I had a buddy get this and I tried it. It tastes just like Reese's. Bought my own and have come back for another 5lbs. I mix with cold water and it's still fantastic. Highly recommend

Not my favorite
[This review was collected as part of a promotion.] I received the Vanilla Bean flavor. When I opened the container, it was a very strong smell. I added the powder to water. It did not blend well. Trying to get the lumps out proved to be challenging. I ended up putting it in my Ninja blender. It still had a chalky consistency. I took a small sip and I just couldn’t swallow it. That funky smell was exactly how it tasted. Like musty, vanilla baby formula. I’m sure it has plenty of benefits, but I could not stomach it without gagging. I gave some to the kids and husband. It was 4 thumbs down.

Great protein mix
[This review was collected as part of a promotion.] I absolutely love this protein shake mix. Unlike other chocolate protein shakes I have had this one does not have that chalky flavor. It has rich chocolate flavor that goes will with Greek yogurt. I will be trying out the peanut butter one next.

Yummy
Yummy. I was a bit skeptical because Reeses is one of my favorites but it tastes almost exactly like it just slightly less salty than the candy. The protein is filling so is makes a great pre-work or a good dessert if youre craving something sweet but don't want to too much sugar. This helps curve my chocolate cravings at times

Great versatility
[This review was collected as part of a promotion.] The vanilla is very sweet. Easy to mix into baking or overnight oats. You can also enhance the flavor with other things like fruit or whatever your heart desires.

Solid whey option
[This review was collected as part of a promotion.] I was sent the vanilla bean flavor of the C4 whey protein. The protein-to-calorie ration is favorable if you’re looking to bulk or add some protein to your diet, and the vanilla bean flavor is appetizing and not synthetic-tasting.

Taste great
[This review was collected as part of a promotion.] I was very surprised with the taste. I received the hersheys chocolate and it was soooo good. I just mixed with water and had to shake it for a minute and it was good to go. I will be trying with some oat milk though and blending it up. It’s a huge size and you get a huge portion. I definitely recommend! A lot of other protein powders I’ve tried are very chalky but this one was super good.

would recommend
[This review was collected as part of a promotion.] This protein powder tastes exactly like a reese’s peanut butter cup. It’s a little hard to mix and can get chalky. Overall, it tastes really good and would recommend.

Not great
Not very good. It caused serious bloating issues, and diarrhea each time I tried it. It did not mix very well, even after 50-60 seconds of blending there were still large chunks. I tried it due to my old protein being discontinued, and I guess I need to keep looking.

Chocolate goodness!
Was excited to try these new protein flavors and they did not disappoint. I got both the chocolate & Reeses. The chocolate is probably my favorite. The Reeses is good too but not as peanut buttery as I expected but then again that would bring the calories up, plus you can just add your own peanut butter in. I prefer to mix the 2 flavors together. Definitely my new go to protein. Mixes well and smooth tasting.
