Amino Z High-Stim Pre Workout

There are pre workouts and then there are PRE WORKOUTS, and we can confirm that this is one of the latter.

If you are after an option that will take your session to the next level, then look no further. This high-stim supplement has been formulated using the best scientifically supported ingredients to ensure that your intensity does not drop an inch all workout.

Prepare yourself for laser like focus, enhanced mental clarity, insane energy, and sleeve stretching pumps for the entirety of your session.

Enter the Amino Z High-Stim Pre Workout.

Ingredient Profile

We have combined eight unique ingredients that act synergistically to ensure that you get the most out of your workout every single time.

Citrulline Malate (4000mg)

Citrulline malate boosts the production of nitric oxide in your body. Because nitric oxide is a vasodilator (opens up your arteries and veins), this increases blood flow to your muscles, giving you a wicked pump in the process.

More importantly, supplementing with citrulline can cause significant improvements in gym performance. It does this by increasing the number of reps you can do, or even adding a couple of kilograms to the bar [1]. 

As cool as this is in the short term, over a longer duration it means faster improvements in strength and size.

Moreover, research has also shown that citrulline can limit the accumulation of fatigue during your workout [2], while also enhancing recovery between sessions [1]. This maximizes session quality, and ensures you get the most out of every workout.

The 4000mg dose in this pre-workout aligns with research recommendations.

Beta Alanine (3200mg)

Beta-alanine is a specific type of amino acid your body uses to produce the compound carnosine -- which helps prevent lactic acid accumulation in muscle.

As a result, taking beta alanine before your workout has shown to improve muscular endurance, while limiting intra-session fatigue [3]. Over time this means you get more out of your training, leading to better muscle growth and faster fat loss [4]. 

Pre workouts containing beta alanine are required during any good bulking OR cutting phase. 

The 3200mg dose we use is markedly higher than the industry standard of 2000mg.

Glycerol Monostearate (1500mg)

Glycerol Monostearate is a type of hydrating compound that comes from glycerol -- a substance that builds the colourless parts of fatty tissue.

This unique supplement improves fluid retention and cellular hydration in your body. In this manner, when it is consumed with liquid it promotes fluid uptake into your muscles, greatly improving nutrient delivery.

Glycerol monostearate supplements have shown to enhance exercise performance and prevent fatigue accumulation, which is imperative to ensuring you get the most out of every single training session [5].

The 1500mg we use is consistent with the literature.

Caffeine Anhydrous (350mg)

Caffeine is arguably the most effective performance boosting compound on the planet. It has been shown to improve mental alertness, attention, and reaction time [6], while also enhancing strength, power, and endurance [7].

As a result it concurrently improves both the mental and physical aspects of gym performance in a very big way.

It is well established that an effective dose of caffeine should sit between 200 and 400 milligrams. We have opted for the higher end of this range to make sure you get everything you need in a single serve.

Pink Himalayan Salt (100mg)

Much like the glycerol we discussed above, salt has also been shown to enhance the uptake of fluid into muscle tissue during exercise. This improves nutrient delivery to your muscles, while also boosting energy production. 

As a result, salt will not only give you extreme pumps in the gym, but also improve both exercise performance and post-exercise recovery in a significant manner [10, 11].

We have opted for high quality pink himlayan salt in this pre-workout to ensure you are not getting any of the nasty chemicals that can come with cheap iodised table salt.  

N-Methyltyramine (50mg)

N-methyltyramine is a powerful compound found in the bitter orange plant.

This supplement interacts with the neuroendocrine system to stimulate the secretion of noradrenaline -- the neurotransmitter that promotes the “flight or fight” response. As a result, it acts as a potent stimulant, increases focus and attention, boosts mood, and promotes improved exercise performance [12, 13].

While the 50mg dosage provided in this pre-workout aligns with best practice in research settings, it is important to note that N-methyltyramine has been banned by the World Anti-Doping Agency (WADA) for use during competitive sports. 

This does not mean the supplement is illegal, and obviously you will have no issues using it the gym, but is something you should be aware about

Huperzine-A (200mcg)

Huperzine-A is a fairly new supplement that is considered to be “acetylcholinesterase inhibitor” -- which means it stops the compound acetylcholine from being broken down in your body, which leads to acetylcholine accumulation.

Now, it is well established that acetylcholine facilitates muscular contraction and staves off fatigue. As such, Huperzine-A supplementation has been reported to increase muscle recruitment, boost muscle strength, and ultimately enhance your performance in the gym [14].

The 200mcg dose provided aligns with research recommendations. 

Final Message

If you are after one of the most potent pre workout supplements on the market, then look no further. 

Combining 8 scientifically supported ingredients into one unique supplement, the Amino Z High Stim Pre-workout has everything you need to take your workout -- and your results -- to the next level.

This is an awesome pre-workout for those that like it STRONG.
Not loaded with under dosed junk like so many others, just a few proven key ingredients at the right dosage.
Taste is great also.
Start with a half dose unless your a seasoned stim junkie.
Good value, will buy again.

Best value pre-workout

By Daniel reviewed on 8/12/2021

Verified buyerA verified buyer is someone who has purchased this product from Amino Z

Great value for money, I buy the high stim and use half a scoop with my low caffeine tolerance. Compared to other brands with similar ingredients AminoZ high stim works out to be super value. The smells are so enticing, especially the pineapple coconut. It smells like a pina colada when you stick your nose in. Only issue I have is it starts to clump if you have it open for a few months.

The batch I received was so clumpy it was impossible to use, they re-sent the order again, same problem all over

3 stars though because they did attempt to fix the issue and when they screwed it up a second time they gave me the a full refund minus shipping

So at least the customer service is solid

clumpy pre

By Steve reviewed on 3/12/2021

Verified buyerA verified buyer is someone who has purchased this product from Amino Z

i have enjoyed most of your products to date. however the hi-stim pre workouts were all super clumpy and did not mix very well. one of my packages would not seal due to pre-workout clumped around the sealing edges.

appeared on both flavours so it was not an isolated incident. Disappointed and did not feel like it was more stim than the normal cmoplete pre-workout which i now prefer.
