Inside Look at the Chris Bumstead Pre-Workout Supplement by Jacked Factory

Wondering what makes the new BUM pre-workout by Jacked Factory such a fan favorite? Read on as we give you the full scoop (no pun intended) on why reigning Mr. Olympia Classic Physique champion Chris Bumstead supplements with this "thavage" pre-workout powder before he hits the gym.

Why Chris Bumstead Supplements with BUM Pre-Workout Powder

If you're a bodybuilding aficionado, odds are you're familiar with Chris Bumstead (aka "Cbum"). The Ottawa native is currently just 26 years of age (as of February 2, 2021) and has already won two Mr. Olympia Classic Physique titles.

Bumstead's Instagram following is in the millions. Naturally, he's revered for his intense training style and bodybuilding accomplishments, but much of his content goes beyond pumping iron and fitness. Once you look past the Mr. Olympia-worthy physique, you'll notice Chris Bumstead has a charismatic, down-to-earth persona. He's one of the most approachable IFBB bodybuilders out there, with an endearing lisp that even Chris himself loves to poke fun at (hence, "thavage" = savage).

But of course, when it's time to move some "heavy ass" weight and focus, he dials into his workout routine like no other. To be the best Classic Physique bodybuilder on the planet, you have to diet and train like the best. (You can learn more about Bumstead's meal plan here.)

To gain a competitive edge, supplements are also key, especially for bodybuilding-style training. Bumstead's workout routine is a push-pull-legs-style split that emphasizes heavy compound exercises and adding weight to the bar. When you're competing at the highest level like Chris, you can't dog it in the gym. You gotta get after it and push yourself.

That's precisely why Bumstead supplements with the special edition Jacked Factory Pre-Workout powder BUM to maximize his workouts. Below, you'll learn what the BUM Pre-workout formula contains and why it's Bumstead's go-to supplement for training like a "thavage."

Full-Scoop Analysis of BUM Pre-Workout

Hard-hitting pre-workouts with tons of caffeine only go so far. After a few uses, you'll start to feel the drawbacks of being "stimmed out," and your training will suffer. Rather than loading up on stimulants, the BUM Pre-workout formula incorporates clinical doses of over 15 active ingredients that amplify blood flow, enhance muscle pumps, boost strength, increase endurance, and optimize recovery when you're tearing it up in the gym.

But make no mistake, there's still plenty of caffeine in BUM to get you going before every training session. You might need to start with a "half-thavage" dose (i.e. half a scoop) to see if you can handle the intensity. And if you're feeling extra thavage, you can dry scoop it like Chris Bumstead does on his way to the gym (fair warning: it hits different).

With that in mind, here's what we included in the BUM Pre-workout formula and how these ingredients take Mr. Olympia Classic Physique champion Chris Bumstead's workouts to the next level:

Pump Igniters: Fermented L-Citrulline & GlycerSize™

Anyone that lifts weights knows there's no better feeling than the pump. The rush of blood to your muscles is oh-so-satisfying when you're banging out reps in the gym. With BUM, we wanted to create a formula that athletes and bodybuilders could depend on to deliver those esteemed skin-tearing pumps every single time they work out.

To accomplish that, we included proven nitric oxide boosters and cell volumizers in high doses, including 6,000 mg L-citrulline (fermented) and 2,000 mg GlycerSize™ (glycerol). Fermented L-citrulline presents uncompromising quality as it's made from non-animal sources while also being arguably the best nitric oxide booster since it acts as a reservoir of L-arginine in the body [1].

The GlycerSize™ glycerol in BUM pre-workout serves as the perfect counterpart to citrulline by maximizing muscle fullness. Glycerol is a naturally occurring backbone of lipids (fats). It is absorbed into muscle tissue and the brain, where it has an osmotic effect by "hyper-hydrating" cells [2]. Note that GlycerSize™ is 65% glycerol by mass, making it much more potent than generic glycerol monostearate, which provides a meager 5-10% glycerol.

Strength and Endurance Boosters: Beta-Alanine, Creatine Monohydrate, Betaine Anhydrous, & Taurine

Each serving of BUM pre-workout packs science-backed doses of creatine monohydrate (3,000 mg), beta-alanine (3,200 mg), betaine anhydrous (2,500 mg), and taurine (2,000 mg). Collectively, these are among the most extensively researched ergogenic aids to date.

Hundreds of studies have shown that creatine monohydrate and beta-alanine can significantly improve max power (i.e. one-rep max), time-to-exhaustion, and body composition over time [3, 4]. They do so by bolstering energy production and combatting shifts in muscle acid-base balance during training. Importantly, these ingredients also have exceptional safety profiles.

You might feel a tingling sensation under the skin after taking BUM due to the beta-alanine, but don't worry; it's a benign, transient effect known as paresthesia that tells you the beta-alanine is working to increase your muscle carnosine levels!

Betaine anhydrous (also known as trimethylglycine) and taurine provide a complementary boost to strength and endurance. Studies suggest these ingredients rapidly increase exercise performance through multiple mechanisms, notably reducing fatigue, improving vascular function, cellular hydration, and mitigating oxidative stress [5, 6, 7].

Energy and Focus Catalysts: Dual-Stage Caffeine, Alpha-GPC, L-Tyrosine, L-Theanine, & Huperzine

Let's be real: You're not going to get a good workout in when your just not "feeling it" mentally. You have to be on your A-game upstairs if you want your body to perform optimally. That's exactly why we cut no corners with nootropics in the BUM pre-workout formula.

You get a hefty dose of caffeine (~300 mg total) from two sources in every serving of BUM since it's unequivocally effective for mental and physical performance [8]. But there's much more on the energy-and-focus front than just caffeine. You also get a whopping 600 mg of high-purity alpha-GPC (glycerylphosphorylcholine), 150 mg L-theanine, 1,000 mg L-tyrosine, and 5 mg Huperzia serrata extract (providing ~50 mcg Huperzine-A).

Okay, that probably sounds like a bunch of hard-to-pronounce mumbo jumbo, but we'll make it simple:

• Alpha-GPC is a bioavailable source of choline, a crucial precursor of acetylcholine and phosphatidylcholine in the brain. Supplementing with alpha-GPC has been shown to improve athletic performance, isometric strength, and cognitive function in several studies [9, 10]. It's also a promising therapeutic aid that may protect against age-related neurodegenerative diseases [11].
• L-theanine is an amino acid that naturally occurs in green tea leaves. It's been a focus of many studies as of late due to its "alert-relaxation" properties and synergistic actions with caffeine [12, 13]. Basically, L-theanine helps you focus and improves mood while tempering the undesirable side effects of feeling a bit too stimulated.
• L-tyrosine is a conditionally essential amino acid (EAA) converted to dopamine and norepinephrine in the body, the former being the chief neurotransmitter involved in reward-motivated behavior. As such, supplementing with L-tyrosine before a workout can improve drive, mood, and cognitive function, especially when combined with theanine and caffeine [15, 16].
• Huperzine-A is a plant compound that inhibits acetylcholine metabolism, thereby prolonging the cognitive effects of other nootropics in the BUM pre-workout formula [17].

Tl;dr — This pre-workout powder will get your mind right so you can get your grind right.

Micronutrient Support: Bioavailable Electrolytes & Vitamins

The BUM pre-workout formula is rounded out with a range of bioavailable electrolytes from coconut fruit powder and pink Himalayan sea salt to ensure the body has ample hydration support during training [18]. We also included vitamins B6, B12, and C as these are essential micronutrients for energy, cognitive function, amino acid metabolism, antioxidant status, and controlling cortisol (stress) levels [19].

Absorption Enhancer: AstraGin®

Last but certainly not least, we added 25 mg AstraGin® to BUM for increasing absorption of the remaining ingredients. AstraGin® is a unique combination of adaptogenic herbs (Astragalus membranaceus and Panax notoginseng) that selectively enhance the permeability of the gut lining in the small intestine [20].

Ensuring the bioavailability of nutrients is imperative when it comes to any supplement formula. If your body doesn't absorb the active ingredients properly, you're not going to get the desired results.
