Customer Reviews
Loved the Carb Killa bars!
I ordered the Carb Killa protein bars, the assorted box, and oh my goodness, they were so good! Every flavor I tried was delicious. My order got here in just 4 days, which was super fast. I will definitely be ordering from them again soon!
Consistent quality always
This was my third time ordering from Grenade, and they've been consistently good. I usually get the .50 Calibre Pre-Workout, and it always delivers. My last order arrived in about 5 days, same as the one before that. It's why I keep coming back; I know what I'm getting, and it works for my gym routine.
Shaker bottle and protein
I got a shaker bottle and some whey protein powder. The shaker is pretty decent, mixes well, no lumps. The protein tastes good too, I got the chocolate. Took about a week to get here, which was fine. Overall, pretty happy with it.
Good products, shipping could improve
I bought a few boxes of the Carb Killa bars and a Grenade Energy drink to try out. The bars themselves are really tasty for a protein bar, and the energy drink gave me a good boost without jitters. The selection box was a good way to try different flavors before committing to a whole box of one kind. My package took 8 days to reach me in California, which felt a bit long compared to other online stores I use. Everything was packed well, but faster shipping would make the overall experience even better. I might order again, but I'd hope for quicker delivery next time.

thinking of stocking up, but worried about shipping. how long does it usually take to get to california?
hey has anyone used those carb killa bars for real? are they actually low sugar and decent tasting or just another chalky protein bar?
how are grenade energy drinks vs monster or bang? do they actually give a good kick without the jitters?
can you stack coupon codes on grenade us? i have one for 15% off but also saw a free shipping thing.
