About The Product: Vapor One

Vapor One (also known as Vapor 1) is a pre-workout supplement made by MuscleTech. It costs $39.99 for 20 servings and considering that it contains 21 ingredients in good dosages, this isnt bad value for money.

In fact, its pretty rare that we award any product above 3.5 stars. So, we are pretty excited by this new addition to the pre-workouts market by MuscleTech.

Ultimately, this is a pretty damn good product. But, it is slightly let down by a few things such as the big dosage of Caffeine Anhydrous and the inclusion of Yohimbe (which is commonly linked to side effects).

Anyway, well expand on this as we take you through MuscleTech Vapor Ones ingredients in the next section. But first, well tell those new to supplements more information about MuscleTech.

Who is MuscleTech? 

If youre not new to supplements, then youll know who MuscleTech are.

They are one of the well-known companies in the industry and have produced some great products; their fat burner, Hydroxycut Titanium is actually one of our highest rated fat burners on the market.

However, youre here to learn more about their pre-workout, Vapor One. So, lets see which ingredients have been added to this product in the section below…

Vapor One Ingredients Explained

As we mentioned before, MuscleTechs pre-workout supplement, Vapor One, contains 21 main ingredients overall; usually, we would consider this amount of ingredients to be too many.

So, what makes Vapor One different? Well, were impressed that MuscleTech has not hidden any ingredients in any proprietary blends and that each nutrient has been dosed well.

Our favorite features of Vapor One are the optimally dosed L-Citrulline, Creatine Monohydrate, and Beta-Alanine; seeing all of these nutrients dosed optimally is quite rare.

However, hardly any supplement is perfect and unfortunately Vapor One is no exception. Some bad things about this pre-workout (in our honest opinion) are that it contains Yohimbe and a slightly over-dosed dosage of Caffeine Anhydrous.

To tell you more, well take you through each ingredient in Vapor One. By the end of this review, youll have a good idea of how safe and effective this pre-workout really is.

MuscleTech Vapor One Supplement Facts Label.

Heres Everything You Need To Know About Vapor One:


We used to have very mixed opinions about Beta-Alanine, here at This is because it can cause you to experience itchy & tingly skin (a side effect known as paresthesia).

However, after trying out numerous pre-workouts containing Beta-Alanine, you do get used to this sensation. And after a while, it is not a problem as you learn to accept it.

Not only that, Beta-Alanine has shown to be beneficial; numerous studies show that Beta-Alanine is capable of enhancing your muscle endurance.

As a result, Beta-Alanine is a good addition to a pre-workout such as Vapor One. But, for first time users, you might find the itching and tingling on your skin slightly strange (remember that it isnt harmful at all, but we accept some people do not like this sensation as we didnt at first).

Creatine Monohydrate 

Creatine Monohydrate is probably the most reliable and proven ingredient available on the market. Ask any athlete or bodybuilder and they will know that this works to improve your strength and endurance.

How does it work? Well, without boring you with too much science, Creatine Monohydrate is able to boost your ATP levels so that you can keep the intensity of your workouts high even towards the end of it; this means that you will feel a bit more of a boost during your last few reps.

As always, though, its important to keep your eye on the dosage of ingredients. With Creatine Monohydrate, we like to see at least 1,000mg in a pre-workout supplement (as some people consume this nutrient separately anyway).

MuscleTech has nailed the dosage in Vapor One; there is a big 3,000mg (3g) dosage of Creatine Monohydrate with each serving, so theres no need to buy this nutrient separately here.

You cant really complain about Creatine Monohydrate, to be honest. Many clinical studies and human trials prove that it works and this has become common knowledge.

Betaine Anhydrous & Choline

Weve grouped these 2 ingredients together because they are both unproven and have been linked with causing fishy body odors.

Now, we dont want to just rule these nutrients out. Were just stating our honest opinion that there have not been enough studies that prove that they work for them to be reliable.

The good news is that they wont cause any side effects that will make you ill. But some studies have shown that they can make your breath and sweat smell slightly fishy.

As a result, we would rather not consume them if we had a choice. But at the same time, the side effect isnt physically harmful so these ingredients are not the worst ingredients in Vapor One.


You might have seen Taurine before, due to it being a common addition to energy drinks. But, its important to know that it has no effect on your energy levels.

So what does it do? Well, Taurine has shown to be capable of preventing cramping during exercise.

Ultimately, the haters can say that you can simply keep yourself hydrated. As a result, we consider Taurine to be more of a bonus ingredient instead of a key addition to Vapor One here.


In terms of being able to improve your muscle pumps while you lift weights, it doesnt get much better than L-Citrulline and Citrulline Malate. Either one is great, so its no problem that MuscleTech has chosen to go with L-Citrulline in Vapor One.

How does it work? Well, Citrulline boosts your nitric oxide levels, which directly increases your blood flow; this allows more blood and oxygen to be pumped into your muscles, resulting in you experiencing better muscle pumps in the gym.

If youre looking at L-Citrulline, then its optimal dosage of 3,000mg. This is great, as Vapor One contains 4,000mg per serving.

As a result, we have nothing to complain about. Good job by MuscleTech here.


This is a patented form of inositol-stabilized arginine silicate.

We have mixed opinions about this. While there have been a few positive studies conducted on this nutrient, we dont believe that there have been enough yet (in our honest opinion).

But if youre going off the few studies that are available out there, then it seems like a positive ingredient. So, while well wait for future studies before making our final decision on this ingredient, it certainly seems promising.

Hawthorn Extract 

Were not quite sure why MuscleTech has added Hawthorn Extract to Vapor One. Its most commonly used by guys using juice, as its shown to help protect your heart health and blood vessels.

There are some studies that suggest that Hawthorn Extract can improve your circulation, which might have a slight effect on muscle pumps. But this isnt proven in enough studies for us to believe that its reliable.

Still, though, improvements to your heart health isnt a bad thing - you dont really need it if youre not juicing though…And we always believe natural is better in the long run, especially for your health (which is why we only promote 100% natural supplements on this site).

VasoDrive AP

In case youre wondering, Vaso AP is a patented ingredient thats believed to improve your muscle pumps.

Were not quite sure why MuscleTech felt the need to add this to Vapor One; it already includes a great dosage of L-Citrulline, which is proven to get the job done on its own.

Ultimately, while this might work, we would have preferred to see something that adds another benefit such as L-Carnitine; L-Carnitine has shown to be capable of reducing muscle fatigue and damage in clinical studies.

Caffeine Anhydrous 

In terms of stimulants, it doesnt get much better than Caffeine Anhydrous. This is a pure form of caffeine thats been dehydrated into powder form, so that it can be added to supplement powders and pills.

So, the main thing is that it works to boost your energy levels and focus in the gym. In fact, this might be why you consume coffee or tea on a daily basis while at your day job,

However, as almost all coffee lovers will know, even too much of a good thing is bad; if you consume too much caffeine, then youll be at risk from jittery side effects and the dreaded energy crash.

For this reason, we always try to choose products that contain under 200mg per serving in pre-workout supplements. Weve found that this is our sweet spot for us, personally, which means that the 350mg dosage in Vapor One is slightly too much for us.

It depends on your tolerance. If you consume bucket loads of coffee daily, then you might be able to handle this 350mg dosage (but we dont recommend consuming any other caffeinated products on days that you do).

The bottom line is that we wish MuscleTech had reduced the Caffeine Anhydrous dosage to under 200mg per serving to help keep more people safe from jitters (in our honest opinion).

Choline Bitartrate 

Choline is a compound thats naturally produced by your body. You can consume more through your diet in foods such as eggs, broccoli, meat and fish (or through supplements such as Vapor One).

This ingredient has shown to be capable of improving your sporting performance. But its also capable of making your sweat smell fishy when consuming more than 550mg per day (which is the tolerable upper level for Choline).

As there is only 200mg here, it shouldnt cause any side effects.


L-Theanine has shown to be very effective when consumed with caffeine; it is capable of enhancing the effects of caffeine.

However, as there is a 350mg dosage of Caffeine Anhydrous of Vapor One, its not going to save those with a low tolerance from jittery side effects.

Japanese Raisin Tree Extract

Also known as Hovenia Dulcis, the extract of this tree found in Asia has been used in Japanese and Chinese traditional medicine for decades as a laxative and treat liver disease.

However, we dont believe that there is enough solid evidence that this ingredient can improve your gym session. So, we dont think that this is a useful nutrient in MuscleTechs Vapor One.

Yohimbe Extract 

Yohimbe Extract is a form of stimulant thats been used in many fat loss studies with some success. However, in big dosages, its also linked with very harmful side effects so its not something we would want to consume on a regular basis.

Not only that, MuscleTechs Vapor One is a pre-workout supplement; if your main aim is to lose body fat, then you should take a look at fat burner supplements instead.

MuscleTech Vapor One Side Effects

There are a couple of ingredients that potentially might cause side effects. However, were not concerned by most of them; only Yohimbe Extract in MuscleTech Vapor One has shown to cause harmful side effects in the past.

We will also mention that Beta-Alanine can cause itching & tingling and L-Choline can cause fishy odors in your breath & body sweat. But, as you can see, these arent going to negatively affect you in the long term.

With that being said, we wouldnt advise anyone to consume any pre-workouts or fat burners containing Yohimbe Extract.

Here are the potential side effects of taking MuscleTech Vapor One: 

  • Anxiety (Yohimbe Extract)
  • High Blood Pressure (Yohimbe Extract)
  • Rapid Heartbeat (Yohimbe Extract)
  • Tingling & itching (Beta-Alanine)
  • Fishy Breath & Sweat (L-Choline)

MuscleTech Vapor One Review Conclusion

There is no doubt that MuscleTech is a respected company in the supplement industry. They have sponsored some big names in the business and released some great products in the past.

But, will MuscleTech Vapor One be remembered as one of their better pre-workouts? Our honest opinion is maybe.

For the price of this product, you get some great ingredients in optimal dosages; our favorite picks include Beta-Alanine, Creatine Monohydrate and L-Citrulline. However, the unnecessarily large 350mg dosage of Caffeine Anhydrous (which might cause some people to suffer jitters) and Yohimbe Extract let this product slightly down for us.

As a result, we think that a 4-star rating is a very fair conclusion for MuscleTech Vapor One. In case youre new to our site, we rarely give 4 stars, so this is certainly still a big compliment to this pre-workout supplement.

MuscleTech Vapor One Review

Bottom Line

While MuscleTech Vapor One has many great features, including optimal dosages of effective nutrients, there are a few small things that let it down; this includes the slightly big 350mg dosage of Caffeine Anhydrous and Yohimbe Extract, both of which can cause side effects.

For this reason, MuscleTech Vapor One is very deserving of a 4-star rating, but cant quite defeat the 5-star fat burners at the moment (in our honest opinion).
