Bodybuilders who include the best pre-workout supplements that boost nitric oxide for better vasodilation and muscular "pump" in their workout routine may notice a significant improvement in muscle hypertrophy.
As an athletic trainer and bodybuilder, I spent years analyzing and testing many pump pre-workout supplements that boost muscle pumps, which I now recommend to several of my fitness clients.
In this review, I'll detail the best pre-workouts for pump, and explain why our recommended supplement can help you gain muscle mass faster.
Our Top Pre-Workouts for Pump (February 2023)
1 - Gorilla Mode (Editor's Choice)
Gorilla Mode has been getting a lot of attention in the fitness community lately because it’s marketed as “aggressively dosed,” which means that it’s formulated to provide the maximum dosage of ingredients per serving.
Each pump pre-workout serving contains 4.5 grams of l-citrulline. However, a daily dose is equivalent to 2 servings with 9 grams of l-citrulline. It also contains caffeine, which gives you the laser mental focus, energy, and endurance without jitters.
The Gorilla Mode formula ensures you get the most out of your pumps. This pump pre-workout helps you do more reps while decreasing the duration between rests. Before long, you will notice insane pumps and pronounced muscles.
- L-Citrulline : 4500mg
- Creatine Monohydrate : 2500mg
- Caffeine : 175mg
- Agmatine Sulfate : 1000mg
- Contains a blend of L-citrulline, caffeine, creatine, and other best pump-inducing ingredients
- Shown to increase mental clarity
- May be used for bulking or endurance training
- Tastes better than most products we’ve tested so far
- We did not encounter any shortcomings with this product
I typically recommend this pump pre-workout to my clients who are seeking help increase muscle growth to bulk up. However, based on some online user reviews, it may also work for endurance workouts.
This stim-free pre-workout is also reasonably priced while offering a high level of quality compared to other pre-workouts.
Gorilla Mode pre-workouts may be too strong for some people -- so it’s better to start with one serving (1 scoop) and see how your body will react to it.

2 - 4 Gauge
4 GAUGE offers a “Made in the U.S.A.” pre-workout that hits all the marks regarding pumps, focus, energy, and hydration.
A good dose of L-citrulline D-malate, an amino acid precursor to nitric oxide, will get you the pumps at the gym. Nitric oxide is a vasodilator, so boosting nitric oxide levels will provide more oxygen to hard-working muscles, increasing performance and promoting recovery .
By combining caffeine and L-theanine, 4 GAUGE provides a formula that can enhance energy and focus without a crazy amount of caffeine to cause jitteriness; a big plus for many of my clients who tested this pre-workout for a few weeks.
I liked the unique addition of coconut water powder to the formula, as it can help maintain hydration and restore electrolytes after a challenging workout.
There are good discounts and bonus goodies for bulk purchasing directly from the 4 GAUGE website.
- L-Citrulline DL-malate : 6000mg
- Creatine Monohydrate : 1000mg
- Caffeine : 150mg
- Coconut Water Powder : 300mg
- A solid dose of L-citrulline DL-malate to boost nitric oxide levels
- Coconut water powder to promote hydration
- Gun Club subscription saves you 10% on each bottle
- Many users report clumping issues
3 - Altius Pre-Workout Supplements
Altius was a brand I had only heard of, but I was pleasantly surprised by the formulation and effectiveness that I have experienced.
What stood out for me the most is the added creatine, which is great because it means you can save taking an additional stim-free pre-workout supplement.
In the majority of Altius pre-workout reviews, there was a lot of positive feedback about the increased strength and best pumps they were able to achieve, and I personally saw it with the clients that helped me do some before and after testing.
- Vitamin B12 : 500mcg
- Citrulline malate : 8000mg
- Creatine Monohydrate : 3000mg
- Citrulline malate and beta-alanine for strength, performance, and pumps
- Creatine can help with better endurance for longer sets
- Doesn’t contain any unnecessary fillers
- Good bulk discounts available
- Quite a strong dose of caffeine
While caffeine is a great mental booster, the 325 mg in this pre-workout product is quite high, especially for women or anyone sensitive to stimulants. Definitely avoid taking it later in the day.
4 - EVL ENGN Shred
This is a pre-workout supplement that includes most common pre-workout ingredients. I would generally recommend that you use this in the cutting stage of training to achieve more muscle definition.
L-Tyrosine is one of the essential amino acids, and the makers claim that it helps to improve your mood and concentration. It also comes in delicious flavors like Blue Raz, Cherry Limeade, and Fruit Punch.
It’s difficult to say whether this actually helps as there is a significant dose of caffeine as well.
We recently did a full review on ENGN Shred.
- L-Carnitine : 500mg
- Folic Acid : 800mcg
- Beta-Alanine : 1600mg
- Contains thermogenic ingredients
- L-Tyrosine may help with concentration and motivation
- Added vitamins to help with protein and carb processing
- Agmatine Sulfate for pain reduction
- Many users comment that it doesn’t come with an energy crash
- Some nutrition information is hidden behind a proprietary blend
The only thing I don’t like is the proprietary blend of pre-workout ingredients which really should have no home on a nutrition label. But because of the thermogenic benefits, I still like to use it regularly.
5 - Cellucor NO3 Ultimate
Another very simple pre-workout for best pumps is N03 by Cellucor. I had some experience with some of their other post- and pre-workout supplements, but a colleague at the gym introduced me to this one.
The only focus here is increasing your nitric oxide production. As a nitric oxide booster, it increases blood flow.
The pump pre-workout flavors are quite tasty, and it’s even available unflavored, so you can stack with other products or with a smoothie.
- Vitamin C : 250mg
- L-Citrulline : 4000mg
- Clear and simple label with no fillers
- A potent dose of L-citrulline for improved nitric oxide levels
- Good selection of flavors
- Great subscription savings available
- Some creatine for endurance and strength would have been a bonus
This pre-workout is not the cheapest product, but there are some good discounts available with a subscription plan. Also, while all the reviews point to best pumps possible, some creatine for strength would have been a nice bonus.
Another thing that users wished it had is citrulline malate (or l-citrulline mixed with malic acid). The malic acid in citrulline malate has shown to be better at enhancing muscle pumps, while also offering you improved strength, also.
Cellucor NO3 Ultimate is also backed by a 30-day full money-back guarantee.
6 - Vintage Blast
I have to admit, the marketing of this pre-workout product did attract me at first, as the packaging does make it stand out from all other pre-workouts.
But once I looked at the label, I did see that there was more to it.
With added vitamins and D-aspartic acid, I can see why so many people online said this pre-workout wasn’t just good
Check out our full Vintage Blast review.
- Vitamin C : 250mg
- L-Citrulline : 5000mg
- Beta-Alanine : 1000mg
- Added D-aspartic acid to help with recovery times
- Many online reviews point at it providing a steady boost
- Allergen-free and suitable for vegetarians
- Good selection of muscle vitamins
- Better selection of flavors to avoid getting bored of it
This pre-workout is allergen and GMO-free, which is always good to see, but it falls a little short on the flavor side. A few more options would help avoid getting bored with it too quickly.
7 - Dr. Jekyll Nitro X
This pre-workout for pumps is a solid option for anyone who goes training later in the day as it has a limited amount of caffeine.
It’s still enough to boost your alertness and motivation, but not too strong to keep you awake all night.
It has one of the stronger doses of beta-alanine and creatine that I could find among various pre-workouts, and there are plenty of people that confirm that it works well to give you the best pump that feel good.
- L-Citrulline : 1500mg
- Beta-Alanine : 2500mg
- Creatine Hydrochloride : 1000mg
- Helps to keep you motivated
- Good choice of flavors that taste quite good
- Beta-alanine and creatine combine well to increase strength
- A lower dose of stimulants makes it a good choice for everyone who want to achieve the best pumps
- Can be difficult to mix properly
Now, from a flavor perspective, I think this pre-workout is actually quite nice, but you might find it a bit difficult to mix. Not quite a blender job, but you’ll need to give it quite a shake.
With a 30-day 100% satisfaction guarantee, this pre-workout is worth trying to boost those muscle pumps.
8 - Animal Pump
Last on my list of best pre-workout supplements is another product with some really cool branding behind it. Again though, it’s not one of those products that spend more on marketing than actually creating something useful.
This one doesn’t contain caffeine, which is positive if you are sensitive to stimulants.
What I thought was a great idea is that each pre-workout supplements serving is packaged in a separate sachet, so you can just throw one in your gym bag ready to use later in the day, rather than dragging around a large container.
- Magnesium : 72mg
- L-Citrulline : 2000mg
- Very conveniently packed into individual servings
- It's without stimulants making it a good option to avoid jitters
- Scores quite well for flavor
- Nice to see some antioxidants
- Unfortunately, it hides behind a proprietary blend
Back to my pet peeve again, this pre-workout brand hides behind a proprietary blend. While it is free of stimulants, it is difficult to stack with other products to get better results.
9 - Sculptnation Pre-Workout
Sculptnation’s entry in the pre-workout market is built around an "enough to feel it, but not so much that you’ll walk through walls" caffeine dose.
If you’re cutting calories or training fasted, its pre-workout formula is straightforward enough to be gentle on the stomach (most of us can unfortunately remember a pre-workout that didn’t meet that qualification), while also powerful enough to fuel a solid training session.
Along with caffeine, Sculptnation Pre-Workout offers and both tyrosine and L-theanine to help rein in the caffeine and keep it focused on the task at hand. A 3 g dose of BCAAs help prevent muscle breakdown and soreness, as well as some light workout fuel. If you’re training before dawn while others are asleep, this slam-it-and-go pre could be a perfect fit.
- Simple label, no proprietary blends
- Solid caffeine dose
- Often on sale
- BCAAs and nootropics
- Limited flavors
What Ingredients Should You Look for?
Here are the ingredients you should look for in a pre-workout supplement:
1. L-Citrulline Malate
This is an essential amino acid, which means that you have to take it in with your diet (1). It’s not something that your body can synthesize, which means you can end up lacking in it.
In a recent study, a much clearer direct and indirect connection was established between L-citrulline malate and the human cardiovascular system, where it can help to relax blood vessels and boost nitric oxide levels.
This, in turn, will increase blood flow, which will result in more blood, oxygen, and nutrients getting to your muscles.
In my research and experience, this is the best ingredient in pre-workouts.
Another important amino acid in pre-workouts is beta-alanine, but studies are a little bit more inconclusive. However, it positively impacts exercise intensity and duration (2).
Because it basically has no side effects, this is a good one to see on the label.
It doesn’t really give you the best pump but instead, it will help to improve your strength and endurance (3). It’s a critical substance for every cell in your body to process energy.
And that includes your muscles where it can help you to get more out of your training sessions.
In fact, without creatine, energy production during high-intensity bouts of exercise would not be possible. Supplemental creatine has been shown to further enhance this process, a fact not lost on the scores of athletes who depend on it to enhance their performance.
- David Robson, Personal Trainer
This is one to be careful with, as overstimulation can (a) give you the jitters and sleepless nights, and (b) you can become tolerant, and the effect will completely diminish (4).
I like to see it on the pre-workout labels as it also helps improve your focus and motivation.
It's also important to note that some avid pre-workout users have claimed that these pump ingredients are also found in pre-workouts for runners because of the energy boost.
How Do Pre-Workouts for Pumps Work?
Pre-workouts for pumps work by increasing the nitric oxide production in the body with carefully selected ingredients. This dilates the blood vessels, therefore enhancing blood flow to the working muscles.
Pumps also work by increasing the oxygen-rich blood cells in the working muscles, which can accelerate the removal of muscle toxins like ammonia. This results in quicker recovery time between sets and better growth stimulus to perform more repetitions.
When Should You Take Pre-Workout?
You should take a pre-workout supplement for about 20 to 30 minutes before starting your warm-up routine. This will take a bit of experimenting as it depends on how fast you can absorb the active nutrients.
I recommend that you start with pre-workouts 20 minutes before training and see if you start noticing the benefits while you’re warming up and increasing blood flow.
Over time, you can adjust the pre-workout timing to get the best benefits when you need them most in the high-intensity parts of training.
Expectations For Pre-Workout For Pumps
You should expect to notice a bigger swelling of your muscles after taking pre-workouts. Unless you’re going to use some measuring devices, you’ll really have to use your own judgment.
But if you pay close attention or work with a personal trainer, then you should be able to notice the difference.
As well as the benefits from the increased blood flow, you should feel like you’re much better able to deal with your reps in each set.
If you start to add more weight because the burn doesn’t kick in as soon as it used to, then you’re probably on the right track.
And if you pick a pre-workout with caffeine, then your mental focus and motivation should improve as well. Less doubt and more willpower to push through the pain will be the positive impact to look out for.
What are the Side Effects of Pump Pre-Workout?
A pump pre-workout can have some side effects that depend on some factors. We created a list below so you can avoid experiencing these symptoms.
You might find that you struggle to stay focused and concentrate on a task, or you just can’t sit still like a 3-year-old after a can of soda. This is most common if you buy a pump pre-workout supplement with a lot of caffeine and drink a few cups of coffee during the day.
The good thing is that it will wear off within a few hours, and you just need to keep an eye on your caffeine intake. In most cases, avoiding other supplements with caffeine content will do the trick.
Similar to the jitters, excessive stimulation with a pre-workout can mean that you end up staring at the ceiling for most of the night. This will also mess with your recovery as you won’t be able to relax your body and muscles enough.
3. Itchy Feeling
This is very common and quite normal after taking pre-workout supplements. It’s mainly down to beta-alanine and vitamin B3, which can stimulate your nerve endings, especially in your skin and muscles. It can feel like a tingling sensation or even like pins and needles, and will usually only last an hour.
In some rare instances, you can experience some headaches after taking muscle pump supplements, which is usually due to overstimulation from caffeine. This is something to keep an eye on, and possibly switching to a caffeine-free pre-workout option will be the better choice.
Why Do Pumps Matter?
Pumps matter because they can have a huge motivational impact. When your muscles swell and your shirt stretches more than ever before, it’s a good sign that you’re getting closer to the ripped appearance you’re going for.
Secondly, if you’ve ever prepared for a competitive event, you’ll know how important it is to pump your muscles.
Tips For Getting Better Pumps
Whether you choose to use one of the above best pre-workouts or not, there are a couple of things you can do to really make a difference.
1. Drink Lots Of Water
You need to achieve increased blood flow into your muscles and that requires water. And I don’t mean have an extra few glasses of water before training. This needs to be constantly on your radar throughout the day.
2. Don’t Release The Squeeze
When you get to that maximum strain and pain point, don’t give in to what your body wants to do. Releasing too soon won’t maximize the amount of plasma filling your muscle fibers.
3. Avoid Too Much Rest
Some people are tempted to admire the results in between sets and end up spending too much time in a rest phase. Sure, have a look in the mirror, but focus on your plan.
4. Pile On The Weight
Don’t use your usual weight limits and reps. You can go down as low as 2 or 3 reps in a set with something very heavy. This will have a more significant impact and combined with holding the squeeze, you’ll achieve more in less time.
Is Pre-workout safe?
Yes, a pre-workout is safe to take. Unless you have underlying medical or health issues or are allergic to some pump ingredients, you shouldn’t notice any serious downsides to using one.
However, keep in mind that most people will react sensitively to stimulants in some pre-workouts. To be extra safe, you might also want to learn how to make your own pre-workout.
Do pre-workout drinks for pumps work?
Yes, pre-workout drinks for pumps work. When combined with a carefully planned gym routine, you can achieve some really good results and develop a ripped appearance.
Is coffee a good pre-workout to increase your pumps?
No, coffee is not a good pre-workout to increase
Can you take pre-workout on an empty stomach?
Yes, you can take pre-workout on an empty stomach. Doing so will result in the ingredients being absorbed quicker.
Our #1 Recommendation...
Of all the top-rated pre-workout supplements that I have researched and tested out, the one I tend to recommend to my clients is Gorilla Mode.
The reason this might be the best pre-workout for pump is that it is packed with creatine, caffeine, and L-citrulline which all aid in increasing mental clarity. The caffeine ingredient boosts your physical performance by giving you an energy boost.
Between the online reviews, clients’ feedback, and my personal experience, I find that this pre-workout has the most suitable ingredients that can help you achieve the best pumps and workout experience.
