MRI® BLACK POWDER ULTRA™ is a groundbreaking pre-workout formula forged from the very latest in emerging research of performance nutrition. Engineered to drive unprecedented workout proficiency, BLACK POWDER ULTRA aggressively targets and engages 7 key factors that drive training capacity and athletic potential.*


The all-new BLACK POWDER ULTRA gives you
advanced ingredients and compounds to:

  1. Help the Body Generate POWER*
  2. Stimulate Protein Synthesis and STRENGTH*
  3. Fight Muscle and Mental Fatigue for STAMINA*
  4. Amplify Focus, Energy and Reaction Time for INTENSITY*
  5. "Feed" the Pathways that "Fuel" ENERGY*
  6. Preserve and Power Muscle Function for RECOVERY*
  7. Help Boost the Metabolism for Powerful THERMOGENESIS*


Regardless of individual endeavors, serious, goal-oriented athletes and fitness enthusiasts share one thing in common; an obsession with results. In a quest to turn their aspirations into physical realities, they train with a raging fury of training intensity. This can lead to one more shared attribute - the dreaded fitness "plateau." When the mind and body can no longer keep pace with advanced training regimens, all performance progress can come to a screeching halt.*

MRI BLACK POWDER ULTRA was expressly formulated to match the mental and physical intensity demands of hard-training athletes. The potential for BLACK POWDER ULTRA to drive "next level" performance is nothing short of astounding. Each ingredient, compound and technology in this unprecedented formula was selected based on the latest emerging research in performance nutrition. What you get is a pre-workout formula powerful enough to fuel your insatiable drive.*


What would a performance driving pre-workout product be without a focus and training intensity-driving component? BLACK POWDER ULTRA leverages the latest in clinically researched ingredients to bring you an unprecedented, full-on mental performance experience. If you're not in the "working out frame of mind" before your first sip of BLACK POWDER ULTRA... you soon will be. BLACK POWDER ULTRA was designed to engage your CNS and support your energy and focus to razor sharp intensity.*

To gain a better vantage point of how BLACK POWDER ULTRA supports powerful mind-muscle connections, we will start with a little background on how the nervous system works. Nerve cells, called neurons, are filled with "communication chemicals" called neurotransmitters. When a signal reaches the end of a nerve, neurotransmitters are released. The neurotransmitters cross the synapse; the space between the nerve and the receiving cell. The receiving cell(s) "pick-up" the neurotransmitters through receptors that allow for the signal to "deliver its message." Acetylcholine is a primary neurotransmitter in the brain that supports cognition. In muscle cells, acetylcholine carries the signal that engages strong contractions. In this image, you see a close up of a muscle cell receiving acetylcholine. The small indentation on the muscle, just under each nerve ending, is called the post synaptic membrane. The connection between a signaling nerve and the muscle cell that it stimulates is called the neuromuscular junction.*

Your BLACK POWDER ULTRA training drive launches with the time-tested, clinically validated and always reliable power of caffeine. Here are some interesting things to know about caffeine. Caffeine is an FDA-approved ingredient as a stimulant for improving psychomotor performance.i Authoritative sources have documented that caffeine has a stimulating effect on the central nervous system, which results in a temporary energizing effect.ii In addition, a recent meta-analysis of 21 studies examined the effects of caffeine on subjective feelings of vigor and energy. In comparison to placebo, caffeine reduced the rate of perceived exertion during exercise by 5.6% (95% CI: -4.5-6.7%).* In addition, caffeine improved exercise performance by 11.2% (95% CI: 4.6-17.8%).*

Of course, BLACK POWDER ULTRA wouldn't be "ultra" without even more neuromodulating ingredients. Enter Mucuna Pruiens and Taurine.

Here's the scoop on M. pruriens - it's been around for quite some time. In the ancient Indian system of medicine, the Ayurveda and Unani, and also the Chinese system of traditional remedies, M. pruriens seeds were used as a tonic, for the improvement of endurance, supporting the immune system, and more.*iv,v,vi Furthermore, M. pruriens has been traditionally used to support sexual health, and for its possible adaptogenic, and neuromodulator support.*

Now for the Taurine side of the equation. Large amounts of taurine are found in the human brain. This is an important consideration because taurine is known to be involved in central nervous system neuromodulation.vii Taurine appears to have multiple functions in the brain including neurotransmission. To explain why requires getting a bit technical. Taurine it may exert its neuromodulating actions by serving as an agonist at receptors of the GABAergic and glycinergic neurotransmitter systems.*


First, let's get something straight. Nitric Oxide is a powerful signaling molecule in the body. Second, for the Arginine "naysayers" out there, studies reveal that the availability of intracellular arginine is a rate-limiting factor of all types of NOS.ix,x,xi Nitric oxide (NO) is synthesized from L-ARG by NO synthase (NOS) in virtually all cell types.xii,xiii BLACK POWDER ULTRA delivers premium Arginine Alpha Ketoglutarate - an excellent source of nitric oxide-generating fuel.*

One of the key signaling pathways of nitric oxide is in the endothelial cells of the vascular system. There, nitric oxide triggers the smooth muscles that surround blood vessels to relax - promoting vascular dilation. This effect is known as vasodilaton (a.k.a. "hemodilation" in MRI terms). In turn, hemodilation promotes optimal blood flow that drives nutrients to muscles and vascular "pumps."*

Now, it goes without saying that generating more nitric oxide equals greater potential for massive "pumps." That's where CFM Nitro kicks in. CFM Nitro (ACTINOS®) is a powerful fractionated whey peptide that actually upregulates NOS enzymes! NOS enzymes are the "factories" that convert L-Arginine fuel into hemodilating nitric oxide. We are not talking about a small increase in NOS here. One in vitro study has found that lung cells exposed to Actinos (fractionated whey peptides) significantly increase nitric oxide production in a dose-dependent manner in the range of 474% to 1,169%.*


BLACK POWDER ULTRA is a multi-force workout amplifier that works on a broad range of physiological fronts that impact every phase of training performance. So far, we have discussed the neurological and hemodilating power of BLACK POWDER ULTRA - now let's talk stamina.*

We discussed the effects of caffeine as a potent neuromodulators, but did you know that is well-known to also delay fatigue during exercise? According to a recent review article, there is little doubt that caffeine is ergogenic in exercise endurance in situations where fatigue occurs in 30-60 minutes.*xv A meta-analysis of 40 double-blind studies confirmed the ergogenic effects of caffeine — particularly for endurance events.xvi In case you are wondering how this applies to you, "endurance event" can be translated, "marathon training session."*

Now, to help drive your "marathon training sessions" even further, BLACK POWDER ULTRA is formulated with genuine Carnosyn® Beta Alanine as a support factor. Beta alanine is suggested by clinical trials to help delay muscle fatigue and buffer muscle acidosis, which plays a role in physical performance and stamina.* Experimental research indicates carnosine plays a role in the pH buffering capacity of muscle, which suggests its involvement in delaying muscle fatigue.xvii Furthermore, controlled clinical trials suggest that increasing muscle carnosine levels though beta-alanine supplementation can delay neuromuscular fatigue and increase time to exhaustion during cycle ergometry tests.*


If there was a way to get a jump-start on recovery before a workout was even over, the effects on growth and tomorrow's performance could be staggering. There is a way - it's called BLACK POWDER ULTRA! This powerful pre-workout product was ingeniously formulated to proactively address post-workout recovery efficiency.* One of the key factors that allows for this incredible effect is L-Carnitine, a highly researched amino acid.*

One research group surmised that supplementing with L-Carnitine reduced muscle soreness and markers of muscle damage which play a key role in recovery after resistance exercise.*xviii At least two other trials by the same research group suggested that a twice daily intake L-Carnitine produced favorable responses in reducing muscle soreness, metabolic stress, markers of muscle damage and actual muscle damage, thereby having the potential to influence recovery after resistance exercise.


OK, now it's time to fully consider why you want to use a pre-workout product. Of course you want to drive your workout intensity - that's a given. However, the end result that you are really looking for is a chiseled, lean physique. With that in mind, doesn't it make sense to leverage your body's fat-burning potential... during your workout?*

BLACK POWDER ULTRA is fully loaded with key ingredients that ignite skeletal muscle bioenergetics. Translation - this formula is designed to help drive fat-to-fuel conversion. Look, why not use some of your own stubborn body fat stores for energy? It's just sitting there, jiggling with every rep and obscuring your hard-earned muscle anyway.*

To see how this works, we need to have another look at Taurine. Researchers have found that taurine may help support post workout glucose homeostasis.* This means that Taurine may elicit a type of nutrient partitioning effect by helping to drive circulating glucose to working muscles (not fat cells).*

Next, an efficacious dose of Citrus aurantium helps to get fat mobilized for incineration. Technically, this is called lipolysis. Synephrine, one of the primary constituents of Citrus aurantium, has been suggested to activate in vitro lipolysis (i.e., fat breakdown) in human adipocytes via activation of the ß-adrenergic receptor.*

Once lipids are "loosed" from their reserves, they are free and "available" for transport into the mitochondria for energy production. This is where L-Carnitine comes into play. Carnitine has a well-established role in cellular metabolism, particularly related to its ability to transport long-chain fatty acids into the mitochondria so they can be oxidized ("burned") to produce energy. The relevance of carnitine's role in this process is further confirmed by its high concentration in tissues like skeletal and cardiac muscle that utilize fatty acids as a dietary fuel.xxiii,xxiv Mitochondrial fatty acid oxidation appears to be rate-limiting for ATP production from fatty acids in exercising humans.xxv In simple speak - L-Carnitine works as a fat "transporter" by helping to move fatty acids into the cellular furnaces (mitochondria) for incineration (energy production).*


Now, burning some unwanted body fat for energy is a powerful benefit to be sure. However, we want to be certain that there is plenty of powerful muscle underneath to reveal. Otherwise, you might as well keep that layer of fat. Good news; BLACK POWDER ULTRA is fully equipped to support muscle protein synthesis. One key factor that drives this effect is none other than L-Arginine AKG.*

Arginine works on two powerful, muscle-building fronts; it is a precursor to creatine and supports muscle protein synthesis.xxvi,xxvii In addition, arginine promotes mTOR/p70s6k activation.xxviii,xxix,xxx Thereby stimulating protein synthesis and enhancing cell migration. An early signaling event activated by amino acids and growth factors in many cell types is the phosphorylation of the mammalian target of rapamycin (mTOR; FRAP), which is functionally linked to ribosomal protein s6 kinase (p70s6k), a kinase that plays a critical regulatory role in the translation of mRNAs and protein synthesis.xxxi,xxxii That was incredibly technical. Here's a loose translation. First, L-Arginine is a key "ingredient" in the production of creatine. Creatine helps to drive muscle power output by quickly "re-fueling" ATP during short bursts of intense training. Next, the really technical bit, L-Arginine is a key signaling agent that helps to activate muscle protein synthesis (supports muscle tissue repair and growth).*


MRI BLACK POWDER ULTRA delivers everything you demand in a pre-workout product, and more. Never before has MRI engineered such a feat of performance driving perfection. You get a full range of advanced ingredients that drive mental and physical capacity through 7 pathways of performance.*

The MRI BLACK POWDER ULTRA experience engages with a complex of neuromodulators that drive the "mind-muscle" connection and intensity. From the moment the workout begins, the formula's impact on muscle energetics, power and strength are evident. As the training continues, key nutrients fuel energy and drive stamina to help you squeeze out more muscle stimulating reps.* You close your session with a deep breath as the last drop of sweat hits the floor, fully confident that your recovery cycle is already engaged.*
