Tastes Like a Treat, Performs Like a Pro
Why I Bought It: I needed a quick, high-protein snack for post-gym recovery that didn't taste like cardboard. I'm a huge fan of chocolate and coconut, so I had high hopes for this flavor. Taste & Texture (The Pros): Great Flavor (4.5/5): It truly delivers on the promise of sweet coconut and chocolate. It has a rich, slightly decadent flavor that genuinely curbs my cravings for actual candy bars. It’s sweet, but not artificially so. Excellent Protein Count: With 18g of protein and a solid 19g of carbs, this bar is perfectly balanced for that critical post-workout recovery window, or as a substantial meal replacement when traveling. Good Texture: It has a dense, slightly chewy center and is coated in a thin layer of real chocolate. Unlike some bars that are rock-hard or dry, this one is moist and easy to eat. Practical Use & Nutrition (The Cons): Not Low Calorie/Low Fat: At 255 calories and 12g of fat, this is on the higher end for a protein bar. If you are strictly cutting fat or calories, you'll need to account for it, but it's great for sustained energy or bulking. Sugar Content: The 12g of sugar is higher than some zero-sugar alternatives. While it helps with the delicious taste and provides quick post-workout energy, it might be a drawback for very low-carb diets. Melting Hazard: Because it has a real chocolate coating, be careful leaving it in a hot car or gym bag! Final Verdict: If you want a delicious, satisfying, and effective protein bar that works perfectly as a post-workout recovery tool (carbs + protein) or a heavy-duty snack, the Chocolate Sweet Coconut flavor is a winner. It loses one star only because of the higher fat/sugar content compared to some competitors, but if you prioritize taste and efficacy, this is one of the best out there.

Avoid
There was something wrong with these; really dark inside unlike they usually are. Had a funny chemically taste like almond or garlic. Avoid

Synthetic
It has a synthetic taste but it’s still quite nice

Multi useful
Good flavour and not hard work to eat. Also it’s big enough to put behind a car tyre to stop it rolling when your handbrake isn’t working

Tasty
These are so good and remind me of rice crispy treats but these are high protein and high fibre. I’ve tried the marshmallow and the brownie flavour but I always come back to the marshmallow. Highly recommended

I dont like
Taste isn't very nice, consistency also like tile grout. Not nice at all... have tried other flavours and still taste like perfume. Personally not for me.

Great taste and texture
Have been using these for a while and they make a great change from regular protein bars. They are basically the protein version of a rice crispy cake. Taste much better than most protein bars and are also filling after workouts. Would recomend them over many other bars .

Nice but too small
Taste great, used to love them but noticed they've got significantly smaller since my previous order! The wrapper is still the same size but the bar is about 30% smaller.
