My Nutrex Research OUTLIFT AMPED Pre Workout Review

My Nutrex Research OUTLIFT AMPED Pre Workout Review

My Nutrex Research OUTLIFT AMPED Pre Workout Review First Look:

Last night was the first time in about 3 or 4 weeks that I did some deadlifts.

This was because I was still reeling from niggling rugby injuries.

That meant my legs were fucked for all of this time, it was hard enough walking, cycling or even trying to climb in and out of the bucket seats in my Civic Type-R.

However, over the past couple of days, while still visibly bruised along with my ego, I decided that a Thursday evening opportunity to hit the weights would mean deadlifts.

I wasn’t lifting as much as usual, however, 418lbs felt heavy. Very heavy.

I did not want to do any upper body exercises as I will perform those this evening and I had just increased the weight on my flat bench to 451lbs so a rest was required to recover and grow.

Just before I was to enter my lair beneath the living room I grabbed the sachet from Nutrex Research and mixed with water in my shaker.

The taste was good. It mixed well and I gulped it down.


RELATED: We’ve tried and tested the best pre-workout supplement HERE!

Rauwolfia – Studies show that it appears to be a safe and effective treatment for hypertension when used in appropriate low doses.

However, some adverse side effects such as lethargy, sedation, psychiatric depression, hypotension, nausea, vomiting, abdominal cramping, gastric ulceration, nightmares, bradycardia, angina-like symptoms, bronchospasm, skin rash, itching, galactorrhea, breast enlargement, sexual dysfunction, and withdrawal psychosis are not uncommon.

Choline BiTartrate – Choline is mostly used for either its cognitive boosting properties or as a liver health agent, able to reduce fatty liver buildup.

It may also be a stimulant although this is based on anecdote. Requires around 250-500mg per day for cognitive benefits.

Choline does not offer any significant benefits for aerobic capacity, fatigue or training capacity.

Tyrosine – Tyrosine is taken for depression, attention deficit disorder (ADD), attention deficit-hyperactivity disorder (ADHD), the inability to stay awake (narcolepsy), and improving alertness following sleep deprivation.

It is also used for stress, Parkinson’s disease, Alzheimer’s disease, chronic fatigue syndrome(CFS).

Acetyl Tyrosine is a more soluble form of tyrosine.

Creatine – A well regarded supplement overall!

Supplementation increases creatine storage and promotes a faster regeneration of adenosine triphosphate between high intensity exercises.

These improved outcomes will increase performance and promote greater training adaptations.

Caffeine – It stimulates the central nervous system (CNS), heart, muscles, and the centers that control blood pressure to give you an extra boost and hit that PB.

Caffeine Anhydrous is the purest form of caffeine so always look out for it.

This is found in 4 Gauge which is the best pre-workout.

It is also found in Instant Knockout which is the best fat burner available at present.

Betaine (trimethylglycine) – This has been recommended as a compound that will increase athletic performance.

However, results from studies have been quite unreliable thus far of Betaine.

A dose of 12500mg has been linked to increased power output, very minimal increase of workout volume and slight endurance. Then again studies have showed no increase of any of the aforementioned parameters.

Beta-alanine  – Supplementation of this non essential amino acid aids the production of carnosine. That’s a compound that plays a role in muscle endurance in high-intensity exercise.

That said, studies have not exactly been positive nor entirely conclusive.

Taurine – It has been touted that Taurine can help mental performance.

Early clinical research suggested that taurine, in combination with caffeine, glucuronolactone, and B vitamins, can improve attention and reasoning in adolescents, but does not improve memory.

However, there is insufficient evidence to prove this is always the case.

L-Citrulline – This is used as a sports performance and cardiovascular health supplement. L-Citrulline supplementation results in reduced fatigue and improved endurance for both aerobic and anaerobic prolonged exercise.

An increase in growth hormone has been noted with exercise, but not at rest.

L-citrulline boosts nitric oxide production in the body. Nitric oxide helps your arteries relax and work better, which improves blood flow throughout your body.

Supplementing can help lower blood pressure in people with pre-hypertension.

This is often found in the best pre workouts.

To supplement L-citrulline to enhance sports performance, take 6,000 – 8,000 mg of citrulline malate about an hour before exercise.

1, 3, 7, 9 Tetramethylpurine (Theacrine / Tetramethyluric acid) – An alkaloid molecule which can be seen as a structurally modified version of caffeine.

However, although it is similar to caffeine whereby it has a sedative effect at relatively low doses, but where this sedative effect with caffeine is at an impractically low dose with theacrine it is the dose normally consumed by tea.

Research on Theacrine is really too sparse though to cast any real assertions.

Black Pepper (BioPerine) – The extract of piperine, called BioPerine®  in the patented form, has been clinically tested in the United States.

BioPerine®  significantly enhances the bioavailability of various supplement nutrients through increased absorption.


1 sachet before training.

This is a combined amount of just 8000mg.

This does not compare well to many of the best pre workout supplements which will offer over 15,000mg.

It did taste very nice which was summer crush flavor, the consistency was right but I did feel a little bloated from it.

Benefits & Effects:

There are six beneficial ingredients included in this pre workout.

Caffeine is a great stimulant that can effect the CNS which controls muscle and heart stimulation.

Citrulline for once is dosed in the amount required to be effective and I found it to be beneficial.

Rauwolscine can help lower blood pressure. However, doses have to be small otherwise there are a heap of negative side effects that can come with it.

When dosed correctly, Choline Bi-tartrate can offer useful brain function benefits, thankfully, this offers the correct dose.

Tyrosine is great for fighting fatigue which many people experience and particularly when trying to fit gym life in and around normal 9-5, family, looking after children life.

Creatine is an excellent supplement able to increase strength and size, it is low dosed here though.

BioPerine helps your body absorb all of the nutrients so they are used effectively.

How Did It Feel?

This was quite odd.

It took a good 40 minutes to have any real effect.

Strangely I didn’t feel anything from the Beta-Alanine which is usually the first thing you feel.

However, after about 40 minutes I felt like I was coming up, so to speak.

I felt like I had lots of oxygen rushing around me, a little bit high and as if blood flow had increased. This must have been the adequately dosed Citrulline.

I also felt the Caffeine.



Theacrine doesn’t offer any real benefit, no more than Caffeine in terms of stimulation so seems a little pointless.

There’s no evidence that Beta-Alanine nor Taurine can actually offer any benefit.

Then Creatine is a little under dosed, plus it needs to be used cycled rather than just having it on the odd day your workout.

Taurine is not proven to have any benefit.

Beatine is far too under dosed to be effective. We would need 12500mg for it to be beneficial.

My Nutrex Research OUTLIFT AMPED Pre Workout Review Conclusion:

I liked the effects from the Citrulline, normally in many pre workout supplements Citrulline is far too under dosed to offer any benefit to your workout.

I also liked that I could feel the Caffeine. Again, with many pre workouts there’s generally a low overall dose, too few ingredients or too many spread too thinly.

Or we witness a case whereby the dose is concealed within a proprietary blend.

Here, we have some beneficial ingredients but it is still lacking others plus a couple ingredients that are just not proven to work.

Therefore, as it is missing the following ingredients I would not suggest that this pre workout from Nutrex Research is the best. However, it is not terrible:

  • Coconut water
  • Potassium
  • Theanine
  • Rhodiola
  • Carnitine
  • Beet

There is a better product than this that will get you fired up and cause hell in your chosen sport.
