Extreme Stimulant Energy

We’ve sized up some bodybuilding supplements from Nutrex Research here on B5. First up is Nutrex VITADAPT, a multivitamin which has an insane 8,350 percent of the daily value for vitamin B12 (for reference, a minimum daily value of 15 percent is high). That much is sure to help boost heart health and ramp up energy levels.

Another one is Nutrex OUTRAGE, an energy booster which can also double as a pre-workout supplement. Thing is, this product has too many loopholes for our liking (fillers, proprietary blend, unproven ingredients, etc.). We hope the manufacturer smooths out the rough edges sooner than later.

On that note, we have high expectations for Nutrex OUTLIFT CONCENTRATE. This is the third version of the company’s signature pre-workout – it manufactured Nutrex OUTLIFT in 2014 and then came out with Nutrex OUTLIFT AMPED several years later.

Now, the manufacturer presents its latest version, which it dubs “just short of rocket fuel,” per its official website. “Today, we look to offer a concentrate worthy of the OUTLIFT name, one that offers a true fully-dosed performance enhancer, utilizing NO3-T Nitrate technology, all (the) while harnessing extreme levels of energy that will deliver the most intense training sessions,” the same source goes on to say.

Can Nutrex OUTLIFT CONCENTRATE help you power through your workouts?

When a bodybuilding supplement company considers its pre-workout “just short of rocket fuel,” customers will pay attention, for sure. If you’ve been longing for a pre-workout which should get you going, Nutrex OUTLIFT CONCENTRATE seems to fit the bill.

Formulation, 6.1 g

One scoop of Nutrex OUTLIFT CONCENTRATE’s Blackberry Lemonade flavor takes up 6.1 grams. It features seven components which work synergistically to give you the best possible workout.

Leading the charge are 1.5 grams of choline bitartrate. “Studies suggest choline bitartrate is an essential nutrient that increases acetylcholine levels, mental energy, and cognitive processing, while also supporting athletic strength and performance. Acetylcholine supports healthy muscular contractile force which is very important during intense training,” per the product’s webpage.

A study which the International Journal of Sport Nutrition published in 2008 (via supports this claim. It says a “reduction in acetylcholine production can have a marked influence on muscle performance because it inhibits the ability of theα-motor neuron to communicate with the motor end plate in muscle excitation-contraction coupling.”

The same study also says choline supplementation may help keep homocysteine levels (a non-protein amino acid detrimental to cardiovascular function) in check. With that, choline not only helps increase muscle performance, but it also helps boost heart health. It’s a great inclusion in Nutrex OUTLIFT CONCENTRATE.

The second key ingredient is n-acetyl-l-tyrosine, which is equal to 750 milligrams per serving. This is the bioavailable form of the amino acid l-tyrosine, which plays a key role in adrenaline and dopamine production (two key neurotransmitters) in the brain.

Plus, l-tyrosine is also a precursor to norepinephrine, a hormone and neurotransmitter which helps mobilize the body and brain for action. The result: increased energy levels. Long story short, l-tyrosine helps boost memory and cognitive function. No wonder it’s an effective nootropic.

You can also find n-acetyl-l-tyrosine in the aforementioned Nutrex OUTRAGE. That tells you the manufacturer sings this ingredient’s praises. An effective pre-workout perks you up not just physically, but mentally as well. N-acetyl-l-tyrosine helps make Nutrex OUTLIFT CONCENTRATE a well-rounded supplement.

Next up are 500 milligrams of sodium nitrate (as NO3-T) per scoop. “Sodium nitrate is the result of combining the nitric acid with a sodium base, such as sodium hydroxide, or sodium carbonate. Sodium is a well-known mineral and electrolyte in the body that helps support hydration levels and muscular contraction,” per Nutrex OUTLIFT CONCENTRATE’s official website.

Sodium nitrate is not as common as, say, beta-alanine (which you can find in iSatori MORPH XTREME and Animal Fury) in pre-workout supplement formulations. The reason is simple: some studies reveal sodium nitrate supplementation does not make a sound impact on athletic performance.

Hard evidence: a study which the journal Medicine and Science in Sports and Exercise published in December 2012 (via says, “Sodium nitrate supplementation did not improve a 40-min distance-trial performance in endurance athletes.” It seems to us the manufacturer included a questionable ingredient (a trend which continues from our Nutrex OUTRAGE review). We say beta-alanine would have been the better alternative.

Nutrex OUTLIFT CONCENTRATE’s fourth key ingredient is Kaff2 Citrate 50.2 percent (yielding 200 milligrams of caffeine), which takes up 400 milligrams per serving. The manufacturer says it sources this pre-workout’s caffeine content from two sources: Kaff2 Citrate and caffeine anhydrous.

“Caffeine citrate is the ideal stimulant for those looking to increase energy as quickly as possible because it appears to raise caffeine blood levels faster than other caffeine sources. Supplementing with caffeine immediately increases work volume and muscle strength, mental alertness and mood, assists in fat loss and helps you train at a higher intensity level,” per the manufacturer’s official website.

We like caffeine citrate’s fast absorption prowess. The knock against it: its stimulatory effect fades just as fast. Caffeine citrate is also an uncommon pre-workout supplement ingredient. It’s mainly used to treat infants with apnea of prematurity.

On the other hand, caffeine anhydrous is arguably the most common form of caffeine in pre-workouts. It’s the pure, powdered form of caffeine which has a heap of benefits:

  • Increases energy levels
  • Boosts fat loss
  • Improves physical performance
  • Promotes healthy blood sugar levels
  • Boosts liver function
  • Keeps free radicals at bay
  • Increases longevity

While these are impressive, caffeine is still a double-edged sword: it may cause a spike-crash effect, jitters, nervousness, and sleeplessness in some individuals. Bear in mind Nutrex OUTLIFT CONCENTRATE’s grand total of400 milligrams of caffeine per scoop is equal to three to four cups of brewed coffee, per the Mayo Clinic’s official website. If you’re sensitive to caffeine, better skip this pre-workout supplement.

Nutrex OUTLIFT CONCENTRATE also has 300 milligrams of betaine nitrate (as NO3-T) per serving. Betaine is a combination of the amino acid glycine and three methyl groups. It’s also a natural ingredient which you can find in beets, shellfish, spinach, and quinoa. This product uses betaine nitrate, a combination of betaine anhydrous (the pure form of betaine without water) and nitric acid.

Betaine is a precursor to methionine, which helps synthesize the popular bodybuilding supplement ingredient creatine. Increased creatine levels, in turn, help build muscle mass and increase athletic performance. In addition, betaine helps keep homocysteine levels in check, boost fat loss, enhance mood, promote liver function, and boost joint health.

Studies suggest 2.5 grams or so of betaine daily give optimal pre-workout results. However, Nutrex OUTLIFT CONCENTRATE yields just a fifth of that amount (500 milligrams per scoop). A small amount of betaine won’t produce maximum results, but it should work synergistically with other pre-workout components.

In a study involving 11 male subjects who did strength training and supplemented with betaine in August 2013, the Journal of the International Society of Sports Nutrition (via concluded, “Six weeks of betaine supplementation improved body composition, arm size, bench press work capacity, attenuated the rise in urinary HCTL (homocysteine thiolactone), and tended to improve power (p=.o7), but not strength.”

Nutrex OUTLIFT CONCENTRATE’s final ingredient is rauwolscine, which takes up two milligrams per serving. “Rauwolscine is an alpha-receptor antagonist that can block the action of receptors responsible for stopping fat breakdown. Consuming before you train allows your body to keep breaking down fat beyond the point in exercise where it would normally stop, which, in turn, helps to promote longer-lasting energy, endurance, and stamina,” per the manufacturer’s official website.

These benefits are nice and all, but rauwolscine is an untested pre-workout ingredient. The reason: most of the studies on rauwolscine as a pre-workout component involved animal subjects. Experts have yet to conduct more conclusive ones on human subjects.

If you want to torch fat, try a time-tested ingredient such as l-carnitine (which you can find in some pre-workouts such as MuscleTech VITALIGENIX NEURO).

All in all, Nutrex OUTLIFT CONCENTRATE is a balanced pre-workout supplement which should help fire you up mentally and physically. However, questionable ingredients, caffeine content, and the inclusion of sucralose (a.k.a. Splenda) pull its value down. Nevertheless, it’s still worth a shot.

Let’s check out the formula ingredients:

  • Sodium, 240 mg: Nutrex OUTLIFT CONCENTRATE has average sodium content at 10 percent of the daily value. If you’re monitoring your sodium intake, talk to your doctor first before buying this product.
  • Choline bitartrate, 1.5 g: A popular nootropic which helps ramp up acetylcholine levels and regulate muscle contractile force. Choline bitartrate also helps enhance cognitive function and keep homocysteine (a non-protein amino acid which is detrimental to heart health) in check.
  • N-acetyl l-tyrosine, 750 mg: The bioavailable form of l-tyrosine, which is a precursor to the neurotransmitters adrenaline, dopamine, and noripinephrine. These help boost brain function and increase energy levels.
  • Sodium nitrate (as NO3-T), 500 mg: This refers to a combination of sodium and nitric acid. While sodium is an effective electrolyte, studies on sodium nitrate as a performance enhancer reveal it doesn’t produce any profound effects.
  • Kaff2 Citrate 50.2 percent (yielding 200 mg of caffeine), 400 mg: The manufacturer claims caffeine citrate is a fast-acting form of caffeine. Because of this, it helps increase work capacity, strength, and fat loss. However, most scientific studies say doctors use caffeine citrate as a way of treating infants with apnea of prematurity.
  • Betaine nitrate (as NO3-T), 500 mg: A combination of the amino acid glycine and the three methyl groups which helps synthesize creatine levels in the body, increase muscle mass and athletic performance, boost fat loss and liver function, keep homocysteine levels in check, and improve joint mobility.
  • Caffeine anhydrous, 200 mg: The pure, powdered form of caffeine which helps increase energy levels, boost fat loss, regulate blood sugar levels, improve liver function, and keep free radicals at bay. Caffeine may also produce a spike-crash effect, jitters, nervousness, and sleeplessness in some individuals.
  • Rauwolscine, 2 mg: The company claims this ingredient helps incinerate fat and increase energy levels. However, contemporary studies on rauwolscine mainly involve animal subjects. Experts have yet to conduct more conclusive ones on human subjects. Long story short, rauwolscine is an unproven pre-workout ingredient.

Formula Analysis

The manufacturer claims Nutrex OUTLIFT CONCENTRATE is the “Extreme Stimulant Energy” pre-workout which is “just short of rocket fuel,” per its official website. Well, after a thorough analysis, this bodybuilding product seems more like ordinary automobile gas to us.

We’re getting the impression Nutrex products use unproven ingredients (the energy booster Nutrex OUTRAGE is a solid manifestation). Nutrex OUTLIFT CONCENTRATE is no exception – it includes uncommon pre-workout components such as sodium nitrate, caffeine citrate, and rauwolscine.

We get the feeling the manufacturer wants to take the high road and venture into unchartered waters. However, it compromised Nutrex OUTLIFT CONCENTRATE’s quality in the process.

It’s not a bad pre-workout by any means, but it certainly has flaws. The most glaring one, in our opinion, is its formulation. It’s balanced, but it’s not as potent as those of many competitors (if you want a powerful pre-workout kick, try these on for size).

On the bright side, Nutrex OUTLIFT CONCENTRATE includes quality ingredient such as choline bitartrate, n-acetyl l-tyrosine, and betaine nitrate. You can’t go wrong with these. The first two ingredients give Nutrex OUTLIFT CONCENTRATE a bit of a nootropic touch, which is great.

For its part, caffeine has its pluses (increased energy levels and fat loss, improved liver function, etc.) but it also has its negatives (jitters, sleeplessness, etc.). Like we earlier mentioned, this product is equal to three to four cups of brewed coffee. If you’re sensitive to caffeine, skip this one.

We also laud the manufacturer for excellent transparency – it reveals all of the ingredient amounts. This bodes well for customers, for sure.

Aside from its questionable ingredients and caffeine content, Nutrex OUTLIFT CONCENTRATE also has a filler in sucralose (a.k.a. Splenda). This artificial sweetener may increase obesity. Stevia, a natural alternative which helps regulate blood pressure and blood sugar levels, would have been the better option.

Finally, Nutrex OUTLIFT CONCENTRATE doesn’t enjoy the stellar reputation of big-name pre-workouts. Perhaps with a few tweaks from the manufacturer, it will gain more recognition someday.

As a parting shot, Nutrex OUTLIFT CONCENTRATE is not the best pre-workout in the world (not by a long shot). If you take out the unproven ingredients, it will still make a positive impact on your training. With that, we hope the manufacturer replaces the obsolete components with proven ones such as beta-alanine, citrulline malate, and the like in the foreseeable future.


Nutrex OUTLIFT CONCENTRATE has the following benefits, per its official website:

  • Extreme stimulant energy blend
  • NO3 technology for increased muscle pumps
  • Enhanced glycogen uptake
  • Delicious taste

We agree with most of these claims. While it isn’t perfect, Nutrex OUTLIFT CONCENTRATE should help you get an edge for your workouts.

Who Takes It?

The manufacturer intended Nutrex OUTLIFT CONCENTRATE for healthy and active individuals who are at least 18 years of age who want to increase energy levels, endurance, and athletic performance; boost fat loss, enhance cognitive function, and achieve their daily fitness goals.

Any Side Effects?

Nutrex OUTLIFT CONCENTRATE contains a grand total of 400 milligrams of caffeine, which is roughly equal to three to four cups of brewed coffee. Excessive caffeine intake may produce a spike-crash effect, jitters, nervousness, and sleeplessness in some individuals.

This pre-workout supplement also contains sucralose (a.k.a. Splenda), an artificial sweetener which may increase obesity.

If these, or any other ingredient, make you feel doubtful, please consult your doctor before buying Nutrex OUTLIFT CONCENTRATE.

The manufacturer also issues a warning:
