YAJU Over 9000 Pre-Workout Review

Over 9000 pre workout blog

A pre-workout is a supplement that you take before your workout to get more exercise energy, power, endurance, focus and muscle pump to give.

The active ingredients in yaju's over 9000 pre-workout have been carefully chosen with the aim of having an immediate effect on the upcoming training. ingredients that have a charging phase are therefore not included in this formula.

Moreover, only ingredients have been used legal are used in Europe as a dietary supplement.

OVER 9000 Pre-Workout Vs. Other Pre-Workouts

Most pre-workouts you see on the market are actually white label products, meaning the formula comes ready-made from the manufacturer. the problem with this is that these formulas are often under-dosed and contain ineffective ingredients. in fact, it's common for different brands of pre-workouts to have the exact same formula.

YAJU OVER 9000 pre-workout on the other hand, is 100% composed by ourselves and in our opinion it belongs to the best pre-workouts in Europe. Due to strict regulations in the EU, some ingredients, such as Alpha-GPC and Agmatine Sulfate, cannot be used. We have carefully chosen each active ingredient and the dosage is based on scientific research. Read more about this below!

YAJU OVER 9000 - Active Ingredients

What is in yaju over 9000 and why is it in it?

1) L-Citrulline - 9001 mg

L-Citrulline is the most effective nutritional supplement that you can use to nitric oxide in the body stimulate and therefore a very important ingredient in our pre-workout. Why do you think 9001 mg and not 9000 mg? Well then it is OVER 9000!  

Why is nitric oxide important in a pre-workout?

L-Citrulline is a good supplement because it benefits your body helps produce nitric oxide. That's important because nitric oxide makes you blood vessels dilate, which makes you heart has to work less hard and there more oxygen-rich blood flows through your body.

As you older becomes, your body makes less nitric oxide on, what bad is for you heart and vessels. That's why L-Citrulline is useful. It helps your body make more nitric oxide, which gives you... blood vessels healthy to stay.

And here's the fun part: if you enough nitric oxide you have, see you there more vascular out and you have one better pump during your workouts.

Improved endurance of your muscles

Investigation Citrulline has also shown that it can significantly improve muscle endurance. research showed that the group who received a single dose of 8000 mg Citrulline malate used from the third set more repetitions than the placebo group could [1].

The impact citrulline had on the performance increased as there more sets were performed and the group taking citrulline malate had a increase of 52% in the number of repetitions they could perform compared to the placebo group. In addition decreased it also the muscle strain by 40% 24 and 48 hours after training compared to placebo.

Get citrulline from your diet

Citrulline can be obtained from your diet and occurs naturally watermelons.

However, you would have to eat about 1.5 kg of watermelon every day to get 3 grams of l-citrulline, which is the minimum effective dose [2]

To get the maximum effective dose of l-citrulline from your diet, you would need to eat about 5 kg of watermelon per day to get 10 grams of l-citrulline. to get in [2]

That's decent lots of watermelon and is therefore the reason why supplementation of L-Citrulline actually the worth it could be.

Citrulline Malate Vs. L-Citrulline

You may have noticed that some supplements L-Citrulline contain, while others Citrulline malate contain. This is a trick that companies use to target customers mislead.

Citrulline malate is essentially 50% malic acid, (which is much cheaper than L-Citrulline) unless otherwise stated. True Citrulline malate is produced by free L-Citrulline to bond chemically to DL-Malic acid, which unique characteristics produces.

It problem in the supplement industry, Citrulline malate is this chemical reaction not undergoes. It's just one mixture of Citrulline and malic acid without any real chemical bond.

The biggest problem is that the l-citrulline in these products often only contains half the stated dosage. this is because citrulline malate is just a mixture.

Companies sometimes label their products as "citrulline malate" or "l-citrulline malate" and pretend that you are getting a high dose, when in fact you are only the minimum effective dose of 3 grams per serving.

Sometimes companies adjust the ratio slightly to get more citrulline to the cheaper malic acid, but this is rare and usually no higher than a 2:1 ratio.

This means that even if you think you are getting a large dose, you are actually only getting 4-6 grams of l-citrulline.

In short, it is important to know what you are getting in your supplement, especially when it comes to L-Citrulline and Citrulline Malate, as the labeling is sometimes misleading could be. Make sure you choose a product with the correct dosage for the best results.

2) Betaine Anhydrous - 2500 mg

Betaine, also Trimethylglycine called, does its job as methyl donor and osmolyte in the body.

As an osmolyte, betaine provides the fluid levels inside and outside the cells balance to bring and as a methyl donor, which means that it methyl groups can to donate on important molecules in the body.

This methyl groups are essential for the production by creatine, a substance that plays a crucial role in the energy supply of muscles.

By providing the body with additional methyl donors via Betaine, it can help to reduce the increase creatine levels.

By the hydration in the cells, Betaine increases the pump that you get and can do in the gym dehydration help during exercise prevent.

2500 mg this research shows one effective dosage to be [3].

3) L-Tyrosine - 2000 mg

L-Tyrosine is really one amino acid that can give your brain a boost. It does this by increasing the levels of certain chemicals in your brain (neurotransmitter levels) in balance to bring.

The main thing that l-tyrosine does is that it is a kind of "building block" is for substances such as thyroxine and neurotransmitters such as dopamine, epinephrine and norepinephrine.

Where it really comes in excels, is in helping you mental acuity, concentration and energy levels. It can also give you a bit of a mood boost to give! [4] [5]

2 grams tyrosine has been proven to be one with this research effective dose to be. [6]

4) Citicoline/CDP Choline - 250 mg

CDP Choline in other words Citicoline is a source of choline and can the outside by repair and renew brain cells.

In addition, it gives a boost on dopamine in your brain and it also helps with a neurotransmitter called acetylcholine which is good for you memory and focus.

When you take cdp choline, it splits into choline and cytidine. cytidine then turns into uridine, and this one Uridine is like building material for the membranes of your brain cells.

And choline gives your brain something staff to sharp to stay and you memory to maintain the level.

250mg is a effective dose based on this research. [7]

5) Caffeine Anhydrate - 250 mg

Caffeine occurs naturally in the leaves, fruits or seeds of many plant species. Caffeine belongs to the group of ingredients that stimulate the central nervous system stimulates. Research has shown that caffeine increases the... promotes concentration, the increases alertness and that it gives you more energetic makes you feel. [8]

This research has shown that: 40 to 50 mg caffeine which is comparable to a small cup of coffee minimal effective dose is. [9]

However, if we talk about physical performance, is the minimum effective dose of caffeine to do things like endurance, muscle strength, perseverance and intense sprints to improve, about 3-6 mg per kilogram of body weight, or about 200-400 mg for someone who weighs 68 kilograms. [10]

However, it is important to note that some people have both cognitive as physical performance benefits can experience with lower doses, while others possible higher doses need to see an effect.

In general, healthy adults can safe up to 400 mg of caffeine per day to consume. [11]

6) Black Pepper Extract - 10 mg

Blacker pepper extract helps inhibit certain enzymes in the body (cyp3a4 and p-glycyprotein). these enzymes break down substances such as caffeine in the body.

Because the prolong caffeine breakdown so you can longer benefit having caffeine. [12]

7) Huperzine A - 0.2 mg

We've already talked about citicoline and how it increases the neurotransmitter acetylcholine, which can lead to better memory and improved focus.

What huperzine a does is it oppose of the breakdown by acetylcholinesterase. This means that it helps to acetylcholine active longer to keep in your brain.

Huperzine a is also known for the production of new neurons in the brain, which is called neurogenesis. It also offers protection on existing neurons in your brain.

Several studies have shown that huperzine a improves memory, focus and overall cognitive function. [13] [14]

Taste and mixability

YAJU OVER 9000 currently has one flavor: Original Ramune. What is Ramune Ramune is actually Japanese soft drink. The original Ramune flavor is a bit similar 7UP or Sprite, but with a hint of bubblegum. It is not so sweet as a western soft drink and our pre-workout does not taste overly sweet, like most other pre-workouts. Plus, it is too not so sour like the other pre-workouts. People are actually decent enthusiastic about the taste so far.

In spite of the considerable amount active ingredients, mixes the product good and you won't get any lumps.

How do you dose yaju over 9000!?

Mix one full scoop (16 grams) with 200-300 ml of water. Give it a good shake or stir to ensure that the powder dissolves well in the water. It tastes best with ice-cold water.

Tip: also mix it with ice-cold sparkling water 😋 Put 200-300 ml of water in a glass and add a full scoop. stir gently with a spoon to mix everything well.

Why are these ingredients not included??

1) Beta Alanine

Beta-alanine is that ingredient in pre-workouts that ensures that you... skin starts to itch. It is often added to pre-workout supplements because it has a noticeable effect when you take it, and people think this effect shows the power of the product.

But let's be honest, beta-alanine's actual impact on performance is minimal at best. while it may have some positive effects in reducing acid fatigue, consuming beta-alanine occasionally, for example just a few times a week, from your pre-workout supplement will do little to nothing.

To really notice the impact on performance, you need to use beta-alanine regularly every day for several weeks, in high enough doses. [15]

In addition, beta-alanine tends to attract a lot of moisture. when combined with other ingredients in a pre-workout, such as citrulline, it can lead to clumping and eventually become a hard, compact mass once opened.

2) Creatine

Creatine is a fantastic supplement that offers many benefits, not just for strength athletes. however, it is important to note that creatine does not work immediately in the short term. It, like beta-alanine, requires consistent daily use over an extended period of time to reach its full potential.

For this reason we have there consciously for chosen not to formulate creatine in our pre-workout. Most people already take creatine separately as part of their daily supplement routine, separate from their pre-workout. This allows them to make optimal use of creatine, regardless of their training times.

3) L-Arginine

L-arginine is a well-known ingredient in pre-workouts for its promise of a better pump as it is supposed to increase arginine levels in your body.

It may sound strange, but L-Arginine is actually not like this effective to increase your arginine levels when you take it. [16]

If you actually want to increase your arginine levels to improve your cardiovascular and metabolic health, l-Citrulline the most effective supplement. [17]

For a significantly better muscle pump, nothing can beat an effective dose of pure l-citrulline.

4) Alpha GPC

In this research [18] It has been shown that taking 600 mg of Alpha-GPC can provide an immediate increase in strength. For that reason, Alpha-GPC was certainly a valuable addition to your pre-workout supplement and was therefore included in the original formulation of OVER 9000!

However, alpha-gpc has recently been added to the european novel food list. this means that it can no longer be sold as a food supplement in Europe.

5) Vitamin C/Antioxidants

One of the less sensible choices is to take antioxidants such as vitamin c before your training session.

The stress and mild damage that occurs during weight lifting or exercise is actually beneficial for the recovery and growth of your muscles.

The reactive oxygen species produced during intense workouts play a crucial role in that recovery process. this also explains why medications such as ibuprofen can significantly hinder muscle growth.

The inflammatory response that occurs in response to exercise is essential for recovery, and suppressing it with antioxidants or anti-inflammatories can prevent your body from properly breaking down and repairing itself, which is necessary for growth.

A pre-workout supplement that's plentiful in vitamins may hinder rather than aid your progress.

6) Theobromine

Theobromine is a substance found in cocoa that has similar effects to caffeine, but to a lesser extent. the interesting thing is that theobromine and caffeine compete with each other, meaning the presence of theobromine the can reduce the effects of caffeine.

Another notable feature of theobromine is that it is soluble in fat. this means that it takes longer for it to be fully absorbed by your body, usually after two to three hours.

You can use over 9000 all year round?

Every now and then it's a good idea to have one pause to take from stimulants and give your body some rest. For example, you could a week without caffeine every month and try other stimulants.


Overall, you can expect this supplement to lead to significant increases in nitric oxide levels, intramuscular hydration, energy and focus.

Caffeine, present in this supplement, provides a powerful stimulating effect.

L-tyrosine, citicoline and huperzine a contribute to cognitive improvement, resulting in increased energy, focus and mental acuity.

In addition, the high doses of L-Citrulline and Betaine for a significant one increase in muscle pump.
