GAT PMP Peak Muscle Performance Pre Workout Review First Look:

Back by popular demand!

Well, sort of, that demand is mine and I am back in the gym.

Yes, I didn’t have enough time to complete all of my sets yesterday so I am back in the gym to perform some shrugs and tricep pull downs.

With no rugby again this week I can afford to hit the weights a bit more without fear or stumbling around aching before the game has even begun.

Plus it gives me opportunity to try out another pre workout. Not that I need an excuse or I have my mother telling me not to because I keep running around the house. If only that was true…at least I would get my washing done for me.

Nope, its just me in my house with my gym and lots of pre workout sample sachets. I wish I got all of these for free as it would be a lot cheaper. And free is fun, right? Like sex unless you go and pay for it.

Here I am with an offering from German American Technologies. A name and brand with heritage and it tells us proudly that this particular pre workout is from the science of NITRAFLEX.

I have yet to try Nitraflex so I have not idea if that is a good or bad hing. Is it like when you see badges on cars that say 16v. Great, it has 16 valves – sort of what is expected anyway…

Well the taste is good which is a start.


Agmatine Sulfate – Agmatine is considered to be a neurotransmitter and neuromodulator. The majority use agmatine injections, not oral ingestion and there is still no evidence that working memory is enhanced with agmatine supplementation.

Glycerol – Seems to be most effective when administered rectally (in your ass) as a laxative.

L-Norvaline –  l-Norvaline showed significant improvement in serum nitrates, urea, LDH, testosterone and testicular protein level in diabetic rats.

There seems to be lots of information on the web about l-norvaline being a wonder drug, however, very little can be found from reliable, scientific sources i.e websites that are not trying to sell it to us.

Sodium – There are mechanisms in place for sodium bicarbonate to be a fat-burning agent (it increases ketone production and lipolysis and causes a minor increase in metabolic rate), but these have not yet been linked to actual weight loss in trials.

L-carnitine – Acetyl-L-carnitine helps the body produce energy. It is important for heart and brain function, muscle movement, and many other body processes.

Calcium – Results show that training results in increased testosterone levels in athletes and that the increase is greater if accompanied by calcium supplementation.

L-Theanine –  Beneficial for stress reduction, decreasing generalized anxiety, and reducing the severity of insomnia. If caffeine is present too, IQ scores have known to increase – so grab a cup of coffee, quick.

L-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).

Vitamin B12 (cyanocobalamin) – Gives you more energy and boost your metabolism, helping you shed unwanted pounds. Ensure you are not deficient in Vitamin B12 so you can do that quick 10 miler at 5am…

Niacin –  Higher amounts of niacin can improve cholesterol levels and lower cardiovascular risks. However, the jury is out on these real benefits.

Thiamine – Thiamine is required by our bodies to properly use carbohydrates.

Some research suggests that taking thiamine together with pantethine and pantothenic acid (vitamin B5) does not improve muscle strength or endurance in athletes.

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 been small and not entirely conclusive.

Beta Alanine does give many users that tingly/itchy feeling. Some love it, others hate it.

I think it is best described at Chillblains – i.e when you go in to a warm room after your hands have been exposed to the cold and they start to feel itchy.

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.

Arginine-alpha-ketoglutarate (AAKG) – Tests on supplementation draw no real benefit that would not be found from resistance training itself.

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 prehypertension.


1 sachet with water which is 8500mg. There’s much better out there.

This sachet is apple envy flavor that was not too bad at all. Although it did bring back memories of waking up to a paramedic taking blood tests.


Beta-Alanine can help with muscle endurance, although not entirely proven. It does feel a little that the tingly sensation from beta-Alanine does take over and become a diversionary tactic.

Caffeine is a great stimulant and good for energy and focus.

Citrulline is great because it helps the body produce more nitric oxide. It is also good for performance, warding off fatigue and increase growth hormone while exercising.

We need Thiamine to properly process carbohydrates. It doesn’t actually improve performance though.

B12 is good for energy, also good for brain and cognitive development.

Arginine is great for blood flow, however, we need 5000mg for it to be effective…we’re a bit short here.

Calcium can help with increases in testosterone levels which is great for overall health and well being, not to mention strength and muscular development.

Theanine helps with brain function and IQ scoring when in combination with Caffeine, which this has for energy and alertness.

Tyrosine is also good for alertness plus a number of other benefits.

Carnitine is often seen in pre workouts and fat burners for its ability to help the body produce energy.

So how did it feel?

As you will see in my video below…I felt nothing at all from this.

While the ingredient profile isn’t that bad overall and I should have felt some noticeable effects I literally felt nothing at all.

Very disappointing. It did taste nice though.

AAKG doesn’t really have an effect in studies.This lack of proven effectiveness extends to Agmatine, Norvaline, Niacin and Beta Alanine – however, Beta Alanine usually makes me feel tingly or itchy – not on this occasion.

I think part of the problem lays with it being under-dosed and the fact this is a proprietary blend.

This means, although each ingredient is listed, under a blend the exact amount of each ingredient isn’t stipulated. This would ring true with Beta Alanine which has its signature tingly feeling, yet with this there was no sensation at all.

This suggests to me that maybe an extremely low amount has been included.

In fact due to the lack of any energy, focus or just anything I would be confident to say that this consists mainly of trace amounts of each ingredient listed in the blends.

It is hard to get around and cheat the system with pre workouts because the user will know within 30 minutes if it is effective or not.

I can tell you now with certainty that this is not effective. It really raises suspicions regarding the ingredient content.

GAT PMP Peak Muscle Performance Pre Workout Review Conclusion:

I am quite shocked and disappointed with this.

While not all of the ingredients are useless and not proven in tests to work, it seems that what has let this product down the most is the overall lack of the mass of each ingredient included.

I think this is hiding behind the proprietary blend with many ingredients only being offered in trace or extremely low doses because if my experience is anything to go by there’s nothing in here.

I know for a fact how some of these ingredients react with me when properly dosed and I felt nothing nor any benefits from this pre workout by GAT.

I would avoid it. GAT also needs to stipulate its content for me to have any confidence in using it in the future.
