PEScience High Volume Pre Workout Review

Can a Caffeine free product really get you pumped for the gym? Our PEScience High Volume Pre Workout review gives us a chance to find out.

Having seen pretty much everything there is to see in the world of supplements, it wouldn’t be surprising if a pre-workout free from Caffeine could genuinely work.

Still, if it is going to really give us what we need, it needs to provide the following;

  • Increased energy
  • Enhanced focus
  • Greater muscle pumps
  • Big gains!

If it cannot do all of the above, then it has no chance of making it onto our top recommended pre workouts list. This is where the best products on the market can be found.

We wouldn’t say that being Caffeine free is a gimmick, far from it, but we are intrigued to see what else they have in their formula to compensate.

Time to find out shortly.

PEScience High Volume Pre Workout Review: Who Makes This Product?

PESciencePEScience High Volume Pre Workout

This Florida based company can afford to take risks on new products since they have a sizeable share of the market.

There is a fair amount of space given to quality control and their thoughts on it on their site. They do say how their GMP facilities are legit and suggest that a lot of other companies’ aren’t.

We couldn’t see anything about a money back guarantee when we looked through their site though.

Their product range has a good amount of products on there. The likes of BCAA drinks to Joint Support formulas. They say it is vegan-friendly and gluten-free which is good to see.

It is a product that seems to sell well on Amazon. Since there are a lot of low-quality products on there, this isn’t something that every company chooses to do. Still, there is nothing from stopping this from being an exception.

They are a fan of a catchy tagline and they say ‘’prepare to feel the volume’’ when promoting this product. Let’s see if it’s all talk.

Now we can really see if this is a product worth buying.

The early signs aren’t great though. They almost stay clear from proprietary blends. This means we get to see just how effective most of the ingredients can be because the dosages are revealed.

However, there are a few ingredients that are bunched together in their Performance Pump Matrix blend that we don’t get the individual dosages for.

This isn’t the biggest blend we have seen by a long margin anyway. Let’s get stuck in.

Vitamin C

This isn’t something we always see in pre-workouts.

It might be useful, but not the most necessary for what we want. It isn’t exactly difficult to get into your system and anyone who has a decent diet will get it from fruits and vegetables of course.

We see the sense of it though, as WebMD says, it is often used to improve physical performance as well as countering the side effects of cortisone. This could mean it is good for building muscle and even testosterone levels.

Still, it is an easy ingredient to get into your diet and not a lot of pre-workouts include it for a reason.

At 250 mg, it isn’t the most potent start but its early days for this product.


This is more like it. An ingredient found in many of our top recommended pre-workouts for a reason.

Citrulline is great for enhancing blood flow. This is so important for this type of product. It turns into nitric oxide in the kidneys, widening the blood vessels. This is what you need in order to get the big muscle pumps and gains that pre-workouts often promise.

Often derived from watermelons, it actually converts into Arginine in the body. This is great for creatine synthesis. Since this product doesn’t contain any extra, this is a useful trait. advise that anything between 6 – 8 g is optimal. The dosage from PEScience High Volume Pre Workout is just 4 g. This won’t have the same effect as a lot of the competition.


Potentially, this is a good ingredient.

It is often mistaken for a stimulant because it is included in a lot of energy drinks. Actually, the opposite is true. It calms the user when the likes of Caffeine are around, making it a good ingredient usually.

Still, this product doesn’t need this trait as it is Caffeine free.

They might be looking for its other potential capabilities. These include its links to increasing blood flow as well as the fact that it is an antioxidant. The lack of human trials are what separates it from the best ingredients for this type of supplement.

There are animal trials which show promise but we are only really into proven ingredients that are really going to work.

Often derived from meats, the fact that this product is vegan-friendly does make it a good source of Taurine.

The dosage isn’t included though as this is part of the proprietary blend.


One study shows how it has been found to aid water retention which can be useful during a workout.

Also, in a placebo-controlled study from the above article, the glycerol supplement was found to have an increasing effect on aerobic and anaerobic performance.

It does seem to have some unreliable results some find it to be useful, but other studies have shown this to not be the case.

This is the brand version called Hydromax. It is believed to be better for hydration as well as performance. It is absorbed quickly by the body.

Because it helps you to retain water, it is linked to increased body weight and since we do not have the dosage information, we can’t say how effective it is.

It appears to be a safe alternative to stimulants but we aren’t sure if it will work here.

Ferula Asafoetida Extract

There must be something in this product that is going to give you gas! describes this ingredient as a supplement catered towards lung and gastrointestinal health and is used as a carminative agent.

They say it may also have benefits for cognition which would be good if it could increase focus – a key trait for a pre-workout.

This is also known as Stinking Gum, Devil’s Dung and Stinkasant – we’re not making it up!!

Traditionally it is used to get rid of wind from the stomach but it is often consumed to reduce flatulence. It’s certainly not an ingredient we see often, we’re just wondering what is in this product that makes it a necessary inclusion.

Also, we don’t have the dosage which would help us determine its usefulness.

There is insufficient evidence to supports its use as a fatigue fighter though.

Arginine Nitrate

An amino acid but one that you are just as likely to find in a testosterone booster.

It can increase blood flow which is something this product needed to give you more of. It also has benefits for sexual health which could make it a useful ingredient.

The issue really is that it is not easily absorbed by the body.

WebMD says that it is necessary for the body to make proteins. By increasing blood flow it does give us what we are after, but WebMD also says that there is inconsistent evidence about the effects of L-Arginine on exercise performance.

It does appear to be able to increase exercise time but taking infrequently will not provide the results you want.

The 2,000 mg falls short of the examples from studies that WebMD provided but could still be useful.

Agmatine Sulfate

An ingredient we are starting to see more often in pre-workouts, but how effective is it? Thought to be able to increase blood flow again, it could also help with muscle recovery. These traits are exactly what we are after.

Agmatine is also linked to reducing anxiety but this isn’t as necessary without any stimulants. The main problem though is the lack of evidence behind it.

It is actually formed from the previous ingredient and is thought to be able to help prevent Alzheimer’s.

It might be able to alleviate pain but as we mentioned, the lack of evidence is what is off-putting.

There are enough animal studies conducted to make it worth following up with human trials, but it seems as though not many have.

The dosage of 1,000 mg appears to be within the safe range.

PEScience High Volume Pre Workout Side Effects

The good news at least is that there doesn’t appear to be anything in this product that should cause side effects.

There is no Beta-Alanine like many other -pre-workouts and of course, without Caffeine, there isn’t the same stimulant like issues around dosages that a lot of companies fail to get right.

It doesn’t take any risks which are good but then again, a lot of the ingredients are ineffective really.

The proprietary blend is only small and the ingredients within it should still be well tolerated so it isn’t as much of a concern as it usually is.

It made it difficult to justify wether or not some of the ingredients should be included, but in terms of safety, they should be fine.

PEScience High Volume Pre Workout Review Conclusion

This may be able to advertise the fact that it is Caffeine free, but this has not resulted in a good product. In fact, this product is worse off without Caffeine, at least this has some proven benefits.

This is what a lot of the ingredients are lacking, proper studies backing their inclusion. There is far too much filler here which has left us with a product that is going to be nowhere near as effective as the market leaders.

When they underdose their best ingredient (L-Citrulline) you know they lack a bit of commitment. The only benefit we could think of from this product is if you want to get a boost at the gym, then go to bed just after!

It is good that it is safe, this, of course, is very important, we just wish it could have been effective as well.

With some strange inclusions and dubious dosages, the company has let themselves down with this one.

We find it hard to see why this sells so well on Amazon. Clearly, people aren’t doing the necessary research to ensure they aren’t wasting money.

‘’Prepare to feel the volume’’ they say – unless this is of complaints because it didn’t work in the way people wanted, we’re not sure it is a reliable tagline.

Stick to the proven ingredients and you will get the gains you are after.
