About The Product

Outlift Concentrate is a pre-workout supplement made by Nutrex. It costs $39.95 on their website for 30 serving containers and comes in 3 flavors – Blackberry Lemonade, Miami Vice and Sour Shox.

We usually find that pre-workout supplements are mostly sour anyway, so we went with ‘Blackberry Lemonade’ flavor, which sounded tasty; it wasn’t bad and was actually one of the better tasting products we’ve tried, which is a big positive.

So we’re hoping that Outlift Concentrate’s nutrient profile proves that it’s worth trying out. But before, that, we’ll tell you more about Nutrex

Who are Nutrex? 

Nutrex are a supplements company that were founded in 2002. Since then, they’ve become a respected company in the supplements industry – even sponsoring high level athletes such as Larissa Reis and Anton Antipov.

We’ve reviewed the precursor to this pre-workout, Outlift AMPED, so we’re interested in seeing whether Outlift Concentrate can beat our highest rated pre-workouts at the moment.

In order to do this, we’ll analyze this supplement’s nutrient profile below.

Outlift Concentrate Ingredients Explained

Nutrex’s Outlift Concentrate contains 7 main ingredients overall, which we’ll analyze for you in this review. From first glance, we’re happy to see that this pre-workout doesn’t contain any proprietary blends (meaning you can see the dosage of each ingredient inside.

However, we also realized that Outlift Concentrate is missing many key pre-workout ingredients; simply put, this pre-workout only seems likely to improve your focus and energy levels, without offering enhanced muscle pumps, strength and endurance.

Ultimately, all of our highest rated pre-workouts offer all of the above benefits – meaning it’s not likely that Outlife Concentrate by Nutrex will compete with them.

Anyway, we’ll take you through each ingredient inside this pre-workout, so you can see how effective it really is.


Here’s Everything You Need To Know:

Choline Bitartrate 

Adding Choline into a supplement is never a good idea.

Why? Because Choline can cause your breath and sweat to smell fishy, without offering any benefits to improve your gym session.

That’s right, Choline is basically a useless ingredient that causes a side effect…not what you want. Personally, we don’t enjoy smelling like salmon in the gym, so we try to avoid pre-workouts containing this ingredient.

Not a good start by Nutrex here, but let’s hope it gets better.


Now, we always have mixed opinions about L-Tyrosine in pre-workouts. Basically, studies have shown that it’s beneficial, as it can improve your focus in the gym.

However, as it doesn’t offer any improvements to your strength, energy or muscle pumps, we don’t consider this to be a key ingredient here. Not only that, Caffeine offers the same benefit as L-Tyrosine, so it’s not needed when a pre-workout already contains Caffeine.

Saying that, L-Tyrosine doesn’t cause any side effects, so there’s no harm in having it in Outlift Concentrate. We just wish that Nutrex would have added Citrulline Malate too (which has proven to enhance your muscle pumps while you lift weights).

For this reason, we consider L-Tyrosine as a great addition to Nootropic supplements – but it’s not needed in pre-workout supplements.

Sodium Nitrate 

If you’re wondering what this is, it’s basically just salt mixed with nitate; in theory, consuming nitrate would increase your nitric oxide levels, which would then enhance your muscle pumps in the gym.

However, the problem is that studies have shown Sodium Nitrate to be ineffective when orally consumed – meaning it’s useless in Outlift Concentrate.

Not only that, consuming more salt in a supplement is never a good idea; everyone consumes enough salt through their diet, so you should stay away from supplements containg sodium.


Kaff2 Citrate 

You might be wondering what this ingredient is, so we’ll just clear the confusion here; Kaff2 Citrate is simply a patented form of Caffeine Citrate (which is a mix of Caffeine, Citric Acid and Sodium Citrate).

Anyway, it’s important to know that Kaff2 Citrate contains 200mg Caffeine. This isn’t good, as Outlift Concentrate also contains Caffeine Anhydrous – increasing your risk of suffering from side effects, such as jitters or energy crashes.

For this reason, we advise you to avoid consuming supplements containing more than one source of stimulant (to stay safe).

Betaine Nitrate 

Betaine Nitrate is simply a mix of Betaine and Nitrate, which is thought to increase your nitric oxide levels. This would enhance your muscle pumps in the gym.

However, studies have shown that Betaine isn’t reliable at delivering this benefit.

Not only that, Betaine is known for causing your breath and sweat to smell fishy (similarly to Choline). Again, we’d rather not smell like a salmon while lifting weights, so we choose to avoid supplements containing Betaine too.

Caffeine Anhydrous 

We mentioned before that too much Caffiene (over 200mg per serving) can cause side effects such as jitters and energy crashes. Well, remember that Outlift Concentrate already contains Kaff2 Citrate, which contains 200mg Caffiene on its own.

Adding this to the 200mg dosage of Caffeine Anhydrous that Nutrex has added into Outlift Concentrate (400mg Caffeine overall) – and you’ll be almost certain to suffer from side effects.

For this reason, we always advise you to consume less than 200mg Caffeine per serving in pre-workout supplements (to avoid jitters and energy crashes).


Rauwolscine is very similar in structure to Yohimbine (which has been banned in numerous countries, such as the USA & UK) after causing harmful side effects). So you imagine that this isn’t a good thing.

What’s it meant to do? Well, Rauwolscine has shown to be able to slightly promote fat loss. However, this has also been reported to cause numerous side effects like Yohimbine. As a result, we believe it’s only a matter of time before the FDA bans this ingredient (the UK have already placed a ban on Rauwolscine).

If you’re looking to lose body fat, then you’ll be benefitted more from a fat burner supplement. However, we advise you to stay away from any supplement containing Rauwolscine.

Side Effects

Out of the 7 ingredients inside Outlift Concentrate, 4 of them can cause side effects; Betaine, Choline, Kaff2 Citrate and Rauwolscine.

As you can imagine, this isn’t great. We always recommend that you choose supplements containing only 100% natural nutrients that haven’t been reported to cause side effects – so you get the most for your money.

In quick summary; Betaine & Choline can both cause your breath and sweat to smell fishy, while Kaff2 Citrate & Rauwolscine can cause numerous side effects that we’ll list below.

Here’s the potential side effects from taking Outlift Concentrate: 

  • Fishy breath and sweat (Betaine & Choline)
  • Low blood sugar (Kaff2 Citrate)
  • Kidney problems (Kaff2 Citrate)
  • Nausea (Rauwolscine)
  • High blood pressure (Rauwolscine)
  • Anxiety (Rauwolscine)
  • Jitters (over 200mg Caffeine per serving)
  • Energy crashes (over 200mg Caffeine per serving)

Outlift Concentrate Review Conclusion

You can see from the list of potential side effects above, why we stopped taking Outlift Concentrate after the first couple of servings. This pre-workout made our heart race, which we expected after seeing the HUGE 400mg overall Caffeine dosage contained inside.

However, we were most dissapointed by the lack of ingredients proven to enhance your muscle pumps, strength and endurance in the gym; we prefer pre-workouts that contain Citrulline Malate and other tried-and-tested nutrients such as Creatine Monohydrate for this reason.

Ultimately, it’s never good when a supplement contains 7 main ingredients, and 4 of them can cause side effects…

For this reason, we can’t advise you to try Outlift Concentrate, and recommend that you look for better options elsewhere (that contain optimal dosages of effective ingredients).
