Five stars — Reese’s lovers, just get it!
This protein powder is honestly amazing — a total 5‑star product that delivers on flavor, mixability, and performance. If you love Reese’s, this is basically a dream come true in protein form. The taste is shockingly spot‑on: rich peanut butter, smooth chocolate, and none of that weird artificial aftertaste most protein powders have. It mixes easily in both water and milk, no clumps, no chalkiness, and the texture stays creamy instead of gritty. I love using it for shakes after the gym, but it’s also perfect in overnight oats or blended with ice for a dessert‑like treat. Energy and recovery feel great with this — it’s a solid whey formula that helps keep me full and supports muscle repair without upsetting my stomach. And the best part? It feels like a treat without blowing your macros. If you want a protein powder that tastes incredible, keeps you consistent, and makes hitting your goals easier, this one is absolutely worth it.

ADDICTED TO THIS FLAVOR!!
Container got a few dents in it during shipping. No big deal, easily reshaped after opening. Low sugar for such an amazing and addictive flavor!! Cures craving for sweets/desserts and keep you full. Great quality and value for the money. Included scooper for easy to measure serving size while staying clean. Will definitely buy again.

Doesn't clump, taste great, and doesn't mess up my stomach
So I bought this knowing very well Reese's isn't my favorite chocolate but I'm trying different proteins out. The price point is at par for what proteins are going for. It mixes very well and I'm a fan of how it doesn't clump up around the bottle an mixes with ease. Best of all, it doesn't mess up with my stomach like the muscle milk protein powder. I loveee the taste and I would buy this again if it goes on sale again

Great flavor, decent value.
7-18-26 the flavor is fantastic. So similar to a real Reese’s cup it’s like a dessert. Blends well with minimal clumping, in a blender bottle. Pretty good deal per scoop at $82 p 5.85lbs. Keeps me full for a long while when mixing in fairlife whole milk. Happy customer.

Good value when on sale
Good tasting protein bought on sale for a decent price. Mixes easily and tastes decent but nothing stands out flavor-wise to make it memorable or a must-order compared to other Whey I've used.
