Giant’s Brew watermelon is absolute 🔥💪🏽

Ever since Nutrithority came out with Giant’s Brew pre, it has just ruined any chance at me ever wanting to try anything else. So many aspects covered within this one from the pump factor, the hydration blend and the focus blend. I’m crushing my workouts and feel like I can keep going even after exhaustion. I tell everybody I can about this one!! Let alone the watermelon flavor is spot on and perfect timing for release this summer 💥💪🏽

Thank you for writing this great review of Giant's Brew Leondro ! We are so happy to hear that you love it and are seeing great results. This pre-workout is the in-house favorite as well :)

Watermelon is tasty

The pump is intense and it gives you the extra pump to push out a few extra at the end of each set. It’ll make ya sweat too pre workout usually doesn’t make me sweat and this one has me like a stuck pig but overall it’s a great product

Giant Brew

I have been somewhat disappointed with the lack of”pump” that I have expirenced. This was the primary reason that I purchased Giant Brew. I have consistently used it four to five times a week.

Great pump!

Needed a new pre-workout for my "rotation". I regularly use 1.21GW so I knew I couldn't go wrong with another product from Nutrithority. It did not disappoint! I had great energy and and greater pump during the workout. This is important since my workouts begin at 5am, or sooner. No crash or jitters.

I am a big fan of 1.21 so I had to give this a shot also. The pumps and energy are just as good if not better. No crash at all after taking first thing in the morning. You can't go wrong with either of these products

We strive to create products that our customers will love, and we're happy to hear that you are a fan of both our Giant's Brew and 1.21. Keep crushing those workouts Joni!

Terrible

Way too much caffeine, didn’t feel stimulated during my workouts or focused, and could hardly sleep during the night anymore.

Thanks for your review Zach. Giants Brew's is incredibly strong...definitely not for everybody. Hope your sleep gets better :)

Works great! With great ingredients

I’m extremely sensitive to pre-workouts but I’m able to take, almost, a full scoop of this without feeling overstimulated! Which is great because the ingredients are exactly what I need/want. Definitely worth a try!

Thanks for taking the time to write this Matt! The ingredients all combine for a smooth workout which we're happy you love too. :)

Taylor G.
Giants Brew

I was running low on 1.21 and Mr. Fusion, so I added this to my lineup. It is most definitely a premium product, although I prefer Mr. Fusion's taste over the Brew. It's hard to compare, so I switch it up some days. Top that with Nutrithority's customer service, I won't buy anywhere else.

Glad you like it Taylor!!!

Awesome product. Meant to order gummy candy flavor but aloha smash wasn’t bad tasting. Definitely will order again.
