K O Punch

long lasting energy

K.O. punch was the best tasting pre-workout I've ever had. Used the whole sample. A little sweet to start with 10 oz of water so I added 2 more oz and it didn't taste watered down. No tingling.

great product no jitters

I took the pre sample in the morning right befor my workout. And I was able to push through the workout without fatigue. I was expecting to be all jittery like all other pre workouts make me but to my surprise no jitters with explosive energy.

Definitely a KO Punch

This product comes bundled with 3 servings in 1 package. I took 1.5 servings and it hit me hard. The affect kicked in within 30 minutes and I felt really good at the gym. My workout was much more intense and I sweat a ton more than usual. The jitters lasted for a few hours after my workout, so I don't recommend this product to anyone who goes to the gym before bed. The flavor was okay and the product mixed okay with 10oz of water.

Big Fan

Having read iffy reviews about grenades .50 Cal pre workout powder I decided to not buy it previously. After receiving it in my 1st JackedPack, I was surprised at how much oomph it gave me for my work out. The flavors are as tasty as the other brands. Overall I will probably be buying this product for future use.

This stuff is liquid lightning!

I took it at noon with my lunch and immediately started feeling a tingeling in my arms and my pupils expanded I went to the gym with lazer sharp focus and destroyed 100lbs dumbells like I was lifting half the weight this stuff is awesome. Great taste and mixed really well I would definitely recommend this for intense training. One drawback I couldn't sleep. Do not mix coffee with this stuff. Lol.

Grenade .50 Caliber Pre Workout Devastator

  • For explosive energy & strength, insane focus, and muscle blowing pumps*
  • Key ingredients support the use of fat for fuel during exercise*
  • University studied ingredients, with industry-leading dosages of key ingredients
  • Great Taste

Grenade: A hard hitting, pre-workout devastator designed to make every workout an explosive, energy fueled assault. .50 Caliber combines over 20 university-tested ingredients and we’re not talking about a little “sprinkling” of “active ingredients”, we’re talking about “Declaring War”! ...up to 3000mg of citrulline, 3000mg of patented Carnosyn® Beta Alanine, 3000mg of Glycerol Monostearate, 1000mg of L-arginine, and enough Yohimbine and other energizing stimulants to ensure that you ‘Devastate the iron’ at every single workout!*

.50 Caliber may also be the only current pre-workout to contain these powerful, high-dosage, clinically-studied ingredients, along with high-nitrate Beta Vulgaris and flavanol-rich Theobroma Cacao - which recent research shown to support exercise performance and blood flow respectively!*

.50 Caliber also delivers BCAA-induced, anti-catabolic support to hard-training muscles, making it truly the ultimate pre-workout ammunition.*

.50 Caliber was formulated by our expert R&D team after evaluating and considering every possible natural component that has been studied to enhance physical performance, strength, and recovery.*

As such, we believe it may be the most dynamic and innovative pre-workout, nitric oxide product available today.

Another major advantage of .50 Caliber is what it doesn’t contain. Grenade researchers made the decision over two years ago NOT to include any controversial and potentially dangerous stimulants in .50 Caliber because our research indicated that they could cause potential side effects along with significant vasoconstriction (narrowing of the blood vessels), which defeats the main purpose of a nitric oxide product, which is the vasodilation (widening) of blood vessels for better performance and a better pump!*

Not only does .50 Caliber contain a ground-breaking combination of NO-boosting, vasodilator, stimulant, and muscle-defense ingredients but the Grenade Research Team simply wouldn’t rest until it was the best tasting pre-workout on the market. So no more choking down bitter, medicinal-tasting, swamp water! You’ll actually look forward to drinking every serving of 50 Cal!
