How I got itNot in hand yet. Recon from the published specs; hands-on review pending

What I Like

  • 25g of protein per scoop with 0g added sugar and gluten free, straight off the label
  • Licensed HERSHEY'S and REESE'S flavors, which matters if flavor is what keeps you drinking the shake
  • Subscribe and Save shown at 30% off the first order with a 20% renewal discount noted, though sale pricing is always subject to change
  • Comes in 28 and 66 serving sizes when stock cooperates

What I Don't

  • No NSF Certified for Sport claim anywhere on the page. The discontinued Whey Sport had it. This replacement does not, so drug-tested athletes should look elsewhere
  • Stock is thin. At research time only the 28 serving HERSHEY'S Milk Chocolate was available; REESE'S, Vanilla Bean, and every 66 serving tub were sold out
  • About $1.61 a serving at full price for the small tub, which is not cheap for a non-certified whey

Straight up front: this is a recon, not a review. I do not have this tub in my kitchen yet. What follows is a coach's read of the published label, and the full review lands once I have lived with it.

Some history first, because it matters. Cellucor used to make Whey Sport, and that product was NSF Certified for Sport with creatine built into every scoop. Whey Sport is gone. The product page is dead and C4 Whey Protein is what replaced it. Here is the part you need to hear: none of the old claims carried over. The C4 Whey page makes no NSF claim and lists no creatine. If you were buying Whey Sport for the certification, this is not that product, and I am not going to pretend otherwise.

The Label Read

The basics are solid. 25g of protein per scoop, 0g added sugar, gluten free. Two sizes, 28 and 66 servings. The hook is the flavors: licensed HERSHEY'S Milk Chocolate and REESE'S Peanut Butter and Chocolate, plus a Vanilla Bean. The candy flavors carry a real license, not a knockoff flavor name.

The catch is availability. When I ran this recon, only the 28 serving HERSHEY'S Milk Chocolate was in stock. Every REESE'S and Vanilla Bean option and every 66 serving tub was sold out. Check before you get attached to a flavor.

Who It Is For

Here is my honest coaching frame. Protein is the one supplement that is still a macronutrient. It is food. You need it every day whether it comes from a chicken breast or a shaker cup, and the best protein powder is the one you will actually drink after training with a carb next to it.

That said, there are two lanes here. Drug-tested athletes and the health-basics crowd should stay on Thorne, because NSF Certified for Sport means a third party verified the label. That lane is covered by the Thorne Whey Protein Isolate, or Transparent Labs Grass Fed Whey if you want more flavor range. C4 Whey is the gym-bag lane, the same shelf as the flavored pre-workouts. If a shake that tastes like a Reese's is what gets you to hit your protein target, that counts for something. Pair it with the boring stuff that works, like creatine.

The Honest Math

$44.99 for 28 servings is about $1.61 a scoop. Subscribe and Save was showing $31.50 on the first order with a 20% renewal discount noted, but treat any sale number as temporary. The 66 serving tub tops out at $82.99 and was sold out anyway. Get it if the flavor lane is your lane. Full review once I have run it post-training for a few weeks.

After Action Report

A candy bar flavored 25g whey for the gym-bag lane, replacing the discontinued Whey Sport without its NSF badge or its creatine. The label reads clean and the flavors will get some guys to actually drink their protein, but drug-tested athletes should stay on Thorne. Full review once I have lived with a tub.
