PUMP AND STRENGTH PROFILE

Pure L-Citrulline

Many other pre-workout products on the market today use a blended Citrulline, known as L-Citrulline Malate. Although the benefits of Citrulline are undeniable, this form only delivers a percentage of the stated benefit of Citrulline. .50 Caliber® is different, formulated using only free form PURE 4000mg dose of L-Citrulline!

A recent study demonstrated that pure L-Citrulline supplementation improves the ammonia recycling process, nitric oxide metabolism and vascular blood flow levels resulting in improved muscular performance.

CarnoSyn® Beta-Alanine

As the name suggests, CarnoSyn® Beta-Alanine is important for carnosine synthesis. Beta-Alanine is an amino acid that bonds with histidine to support an increase in muscle carnosine. Elevated muscle carnosine levels have been shown to:-

• Extend muscular Endurance*

• Combat the build up of lactic acid, which leads to improved endurance and reduced muscle fatigue*

• Build muscle strength*

• Enhance peak performance capabilities*

Creatine Hydrochloride (HCL)

Creatine remains one of the best and most well researched ingredients within sports and athletic performance. It has been shown to support significant gains in muscle strength and power, as well as muscle growth.*

Creatine Hydrochloride (Creatine HCl) is a form of Creatine where hydrochloric acid groups are then bound to Creatine molecules. Adding the HCL group actively lowers the pH of Creatine, making it more acidic. This increase in acidity improves its solubility in fluids, which in turn increases its absorption within the body and further prevents any stomach or gastrointestinal issues.

ENERGY PROFILE

No stimulatory or energy supplement would be the same without the addition of Caffeine. Not only is .50 Caliber® loaded with 300mg of high impact Caffeine Anhydrous, but also two additional forms: Infinergy™ (DiCaffeine Malate) and PurCaf™. 

Infinergy™ is a precise combination of Caffeine and Malic Acid as an ionic bonded compound. By combining the well-established properties of Caffeine and Malic Acid, Infinergy™ offers sustained release energy, extending the stimulatory effects of Caffeine.

PurCaf™ is an organic Caffeine that is 90.5% pure Caffeine extract from green coffee.

Advantra Z™ (30% P-Synephrine)

Known most commonly for its ability to increase resting metabolic rate and therefore, effective in inducing weight loss and reducing body fat* - .50 Caliber® has been formulated with the mindset to not only amplify your workout but assist in utilizing body fat during training or exercise.

Advantra Z®, over many other different forms of P-Synephrine has been shown to stimulate beta-3 cell receptors with minimal impact on alpha 1,2 and beta 1,2 receptors, which means, Advantra Z® increases the metabolic rate (thermogenesis) without affecting heart rate or blood pressure unlike other high stimulatory compounds.

This complete synergistic blend of caffeine and Advantra Z® results in immediate increases in muscle strength, improved muscular endurance and decreases muscle fatigue during workouts, taking your training intensity to the next level*.

MIND-MUSCLE PROFILE

Fundamental to the unique .50 Caliber® formulation is its tri-phased Mind-Muscle Profile. As the initial ingredients are absorbed, the following compounds break the blood brain barrier, enhancing the effect and benefits further, resulting in an amazing cognitive improvement*:-

L-Theanine: 50mg

Reduces stress effects and improves alertness and attention.

Higenamine Hydrochloride (HCL) : 50mg

Stimulates muscle tissue to contract, such as the heart, improving athletic performance.

Huperzine A (Huperzia serrata): 50mcg

A cognitive enhancer that promotes neurotransmitters within the brain promoting alertness.

  1. Best Pre-Workout

    by

    This is by far the best Pre-Workout I have ever used. I have used a few other Pre-Workouts and none of them have given me the great effects that this one gives me. It gives me everything I need to power through everyday workouts after a day at work. Highly recommend this Pre-Workout to anyone who might be wondering about it. I got the Fireball flavor and it is an amazing flavor. This is by far the best tasting Pre-Workout I have ever used as well. With others I have felt myself almost gag at the flavor of them but this Fireball flavor is spot on and goes down nice and smooth.

  2. So Far..

    by

    I'm actually pretty impressed. I bought a pre, intra, and post powder. And I feel pretty happy with my purchase for each. They actually aren't the most expensive powders I've bought, but they aren't the cheapest either. So I'm pretty comfortable with in between. The containers for the pre and intra are actually the same size, which wasn't what I was expecting. But when I thought about it, I've gotten mid sized containers of pre workout powder that was about half full and though I know it doesn't really matter seeing that kind of pisses me off everytime I open one like that. These were pretty stuffed full so what you see is pretty much what you get. Specifically for my Pre, I chose the Orange/Pineapple Powder but I also received 2 samples of other flavors. Unfortunately 1 was the 1 serving of Orange/Pineapple which I had already bought but I'll survive. Free sample is a free sample, Much appreciated! I haven't tried it yet though. I decided to test the other sample first.
    "Fireball". And I have to admit, It isn't the flavor for me... But that's just me. I highly underestimated the name thinking it was just a play on word of the brand lol. One extremely strong "cinnamony" scent and taste. It came with some kick for sure. It made it hard to swallow for me but I forced myself to finish it. But the after effects! Wow! That's what set the difference for me. When they say power through your workout this is one I can say actually backed that statement. I had to go a bit heavier than I usually do just to make it tougher for me to get a good set in that makes me struggle through my last few reps. I've gotten energy and a good pump from a pre-workout before but that caught me off guard. Can't wait to get to the gym and try the other. I think I'm leaning towards the wild punch flavor for my next purchase but I'm definitely sticking around. Hopefully there's some new flavors in the works or something.

  10. My New Go-To Pre-Workout

    by

    I was instantly hooked on this pre-workout. The flavors (I tried both in trial sizes) are phenomenal. Light and pretty refreshing, with no heavy or weird aftertaste. Mixibility was great, too- no chalky or gritty sediment at the bottom of my cup. I took it and within 5 minutes was ready to get to spadework and agility!

    Thanks for another phenomenal product!

  11. Boooommmm!

    by

    First off, grenade did a great job with the new formulated .50 caliber! Let's start with the flavors. ..now if you have ever tried the Welch's orange pineapple juice this is what that reminds me of and I'm not a fan of fruit punch supps BUT this is pretty good like a Hawaiian punch taste. Plus no bad aftertaste or grittiness!

    From my experience. 50 caliber has been great so far, intense energy with pumps & great mental focus and strength! I lift heavy 6days a week and the new .50 caliber has really impressed! But this is just my opinion, gotta try it for yourself!
