About The Product

Outlift AMPED is a pre-workout supplement made by Nutrex. It costs $49.99 for 20 servings and comes in 2 flavors - Fruit Candy or Peach Pineapple.

These flavors sounded pretty interesting, but we decided to go for the Fruit Candy (this seemed to be the products main flavor). In all honesty, it didnt taste bad - but it also wasnt the best tasting pre-workout weve ever had. Does the job, but itst really enjoyable to drink.

Anyway, well tell you about the company behind Outlift AMPED, before analyzing the ingredients inside in the next section.

Who are Nutrex? 

Officially called Nutrex Research; this company was founded in 2002 and is a USA-based company in Oviedo, Florida.

However, we didnt find out much more about Nutrex on their about us section on their website. But one thing we do know - is what ingredients are inside.

So lets take a look below…

Outlift AMPED Ingredients Explained

From first glance, we have very mixed opinions about Outlift AMPED. Basically, were happy that this pre-workout doesnt contain any proprietary blends - but it doesnt contain all the key pre-workout ingredients we look for in these supplements.

Not only that, weve spotted a potentially harmful ingredients - Rauwolscine…but on the other hand, it contains an optimal amount of one of our favorite pre-workout ingredients (Citrulline Malate).

So you can see why we have mixed opinions with Outlift AMPED. Well analyze each ingredient, so you can make up your own mind about this pre-workout below.


Heres Everything You Need To Know:

Citrulline Malate 

As weve mentioned, this is one of our favorite ingredients in pre-workout supplements. Simply put, its shown to enhance muscle pumps in the gym (by allowing more blood to rush into your muscles).

Everyone knows how good being pumped in the gym feels; and as Nutrex has dosed Citrulline Malate optimally (at least 6,000mg per serving), youll be sure to experience this benefit.

Personally, this is one of the ingredients that is essential when choosing a pre-workout supplement. Good job by Nutrex.


This is probably the most controversial ingredient in the supplements industry - it always causes a split in opinions.

Why? Because it can enhance muscular endurance, but it can also cause a side effect called paresthesia.

Whats paresthesia? Well, its a tingling and itching feeling on the skin of your face and body - something that can distract you from your workout in the gym.

For this reason, we choose to avoid pre-workouts containing paresthesia (as do many people who dont like itchy skin). But we do acknowledge that some like Beta-Alanine - which is why weve included it as part of Outlift AMPED pros list in this review.


We just mentioned that Beta-Alanine is both beneficial and causes a side effect. Well, Betaine causes a side effect without improving your gym session at all - making it a useless ingredient in any pre-workout supplement.

So what side effect does Betaine cause? The answer: fishy odors in your breath and sweat.

For this reason, we try to avoid pre-workouts that contain Betaine; it shows that the company havent done enough research when formulating their products.

Creatine Magnapower 

Creatine Magnapower is advertised as one of the most advanced creatine ever created in science labs - but were not convinced.

Why? Because no study has shown that Creatine Magnapower is more beneficial than other forms (or even works).

The fact is, we know that Creatine Monohydrate works, as its been used by athletes and bodybuilders since the 1980s. So we dont know why companies try to fix something thats not broken.

We prefer pre-workouts containing Creatine Monohydrate instead of other unproven forms of creatine. Ultimately, you want to choose tried-and-tested ingredients - instead of those like Creatine Magnapower which is unproven.



This is an organic acid that contains sulfur (not bull urine like some believe). And it doesnt raise energy levels like some believe either.

The only benefit Taurine provides is that it can reduce cramping. However, this same benefit can be achieved when consuming enough water - so Taurine isnt necessary in pre-workout supplements.

However, Taurine isnt the worst ingredient in Outlift AMPED, as it hasnt been reported to cause any side effects.


L-Tyrosine is brain-booster thats shown to improve cognition. However, it hasnt shown to offer any other benefits to improve your gym session.

Ultimately, as Outlift AMPED contains Caffeine, which offers improved focus in the gym - L-Tyrosine isnt needed here. But L-Tyrosine is an important ingredient inside Nootropic supplements.


We dont like Choline for exactly the same reasons we dont like Betaine; Choline has also shown to cause fishy smells in your breath and sweat, without offering any improvements to your gym session.


Caffeine is a key ingredient in any pre-workout, and is the best stimulant you can find in these supplements. Basically, its shown to improve your strength, endurance, energy and focus in the gym.

However, you need to make sure to consume under 200mg per serving in pre-workouts (in order to avoid side effects such as jitters and energy crashes).

As Outlift AMPED contains an overall Caffeine dosage of 350mg, this puts you at risk of suffering from these side effects. For this reason, we only recommend consuming pre-workouts containing under 200mg Caffeine per serving.


Theacrine is another stimulant thats believed to offer similar benefits to Caffeine. However, its not been proven to be safe or effective in any studies - making it an unreliable ingredient.

We always put you (our readers) safety first when writing these reviews. So we cant recommend that you consume a pre-workout containing Theacrine, knowing it might cause side effects.

For this reason, well be keeping an eye out for further studies on Theacrine. But for now, its an ingredient well be staying away from.


This is basically Black Pepper Extract thats been branded. Its a good bonus ingredient, as it can improve the absorption rate of other ingredients its consumed with.

However, it doesnt directly benefit your gym session - which is why we call it a bonus ingredient.


This molecule is one of the ingredients we always avoid in pre-workout supplements. Its known for causing unwanted side effects and has been banned in numerous countries such as the UK.

For this reason, we recommend you to stay away from pre-workouts containing Rauwolscine - to stay safe from potentially harmful side effects.

Side Effects

There are 5 things that can cause side effects in Outlift AMPED; Beta-Alanine, Betaine, Choline, Rauwolscine & and the overload of stimulants.

Simply put, Beta-Alanine causes a side effect called paresthesia (which is a tingling and itching sensation on your face and body). Betaine & Choline both cause your breath and sweat to smell fishy, Rauwolscine causes numerous side effects - while over 300mg per serving Caffeine causes jitters and energy crashes.

This is exactly why we recommend you to consume under 200mg Caffeine per serving (to stay safe from side effects while enjoying its benefits).

Heres the potential side effects from taking Outlift AMPED: 

  • Paresthesia (Beta-Alanine)
  • Fishy smell in your breath and sweat (Betaine & Choline)
  • Nausea (Rauwolscine)
  • Anxiety (Rauwolscine)
  • Dizziness (Rauwolscine)
  • Upset Stomach (Rauwolscine)
  • Jitters (Over 200mg Caffeine per serving)
  • Energy Crashes (Over 200mg Caffeine per serving)

Outlift AMPED Review Conclusion

You can see why were not recommending Outlift AMPED after seeing the list of potential side effects it can cause. Simply put, its missing key pre-workout ingredients and only contains 1 ingredient thats been dosed properly and proven to work - Citrulline Malate.

The biggest mistake made by Nutrex was adding an overload of Caffeine, which causes the most common side effect caused by pre-workouts - jitters and energy crashes. For this reason, we recommend choosing a pre-workout containing under 200mg Caffeine per serving.
