We Need C4’s New Hershey And Reese’s Protein Shakes ASAP

C4 has a new protein shake problem, and it’s a delicious one. The brand has brought its Hershey’s and Reese’s collaborations into a new ready-to-drink format in the UK and Europe. So the flavors that have already made C4’s protein powder lineup much more exciting are now available as bottled shakes.

Unfortunately for American fans, the new shakes have not been announced for the U.S. market.

Hershey’s And Reese’s In A Bottle

C4 and The Hershey Company have already been playing around with these two flavors for a while. The companies teamed up in 2024 to bring Hershey’s and Reese’s flavors to C4 products, including protein powders. The original C4 Whey Protein lineup included Hershey’s Milk Chocolate and Reese’s Peanut Butter, with 25 grams of whey protein in each serving. 

Now C4 has basically taken those flavors out of the powder tub and put them into a ready-to-drink shake.

Hershey’s Milk Chocolate is the obvious choice for anyone who wants a classic chocolate shake. It takes the familiar Hershey’s milk chocolate profile and gives it a protein-focused makeover.

Then there is Reese’s Peanut Butter & Chocolate, which is arguably the more exciting option. Chocolate and peanut butter already have a pretty unbeatable track record. C4’s version brings that combination into a creamy protein shake rather than a candy cup or a scoop of powder.

What You’d Expect From A Protein Shake

Each 330ml shake contains 25 grams of protein, making it a substantial serving for a ready-to-drink beverage. The shakes also have no added sugar. 

The protein comes from milk, so these aren’t plant-based shakes at all. 

This Is Part Of A Bigger C4 Protein Push

C4 has been expanding beyond its better-known energy drinks and pre-workout products. In July 2026, Nutrabolt launched C4 Sparkling Protein in the U.S., giving the brand a carbonated protein drink with 20 grams of protein, zero sugar and no caffeine. 

The new European shakes are a very different idea. Instead of a fizzy drink, C4 is going after the creamy protein-shake crowd.

America Has The Powder, It Needs The Bottle

C4 currently sells Hershey’s Milk Chocolate and Reese’s Peanut Butter & Chocolate whey protein in the U.S., with 25 grams of protein per scoop and zero added sugar.

So the U.S. isn’t completely missing out on the collaboration. It’s just missing out on the ready-to-drink version. C4 hasn’t announced any plans to bring the new protein shakes to the U.S., but there’s still hope.
