Pump Serum Stimulant-Free Pre Workout Review
We realize that stimulant-heavy pre-workouts may not be for everybody, and so do Huge Nutrition.
Following on from their iconic Wrecked Pre-Workout formula, Huge Nutrition has also developed Pump Serum, a stimulant-free pre-workout supplement.
If you’re sensitive to caffeine or other stimulants widely used in pre-workouts, a stimulant-free pre-workout might be a better option for you.
You’ll still have the benefits of increased focus and pumps inside the gym but without the many negative side effects of caffeine, such as jitters or stomach problems.
Huge Nutrition sent us a sample of Pump Serum to test out, and we’re going to be covering an honest review of the product in this article.

Here’s our Pump Serum Pre-Workout review:
Important information
Before discussing the ingredients, prices, and effectiveness of Pump Serum Pre-Workout, let’s quickly cover some important information on the product, such as serving size, servings per container, and container size.
Servings/Tub Size
Each tub of Pump Serum contains 25 servings, and the net weight of a single tub is 775g. This is double the weight that the original V1 formula included.
Scoop Size
Each scoop, or serving, weighs 31g. Again, double the serving content of the original V1 formula, and I doubt you’ll find another stim-free pre-workout on the market with this much content.
Suggested Stacks
Huge Nutrition recommended stacking Pump Serum with their Magnify and Arachidone products. You can buy this specific stack for all three products together on their website.
Pump Serum Ingredients
There are 13 core ingredients inside Pump Serum V2, and it shares many of the same ingredients used in Huge Nutrition’s Wrecked pre-workout formula.
Pump Serum V2 is literally double the serving size of the original formula, which quite honestly makes it one of the best-dosed pre-workouts on the market, and most definitely the best-dosed stim-free pre-workout.
Let’s walk through each individual ingredient and the dosages for them:
L-Citrulline – 8000mg
One of the newer additions to the V2 formula is L-citrulline. It’s one of the most common ingredients used to help produce impressive pumps, and I’m incredibly glad they’ve included it in the new formula.
The clinically effective dosage starts at around 3500mg to 4000mg, with the top end being around 9000mg to 10000mg. Very few pre-workouts include L-citrulline at such a high dosage, with Gorilla Mode being one of the other well-known products for doing this.
GlycerPump™ (65% Glycerol Powder) – 3000mg
GlycerPump is a patented version of Glycerol powder. Glycerol powder has been used in bodybuilding for increasing muscular pumps, and it’s incredibly effective in doing so.
GlycerPump is a much more effective and stable version of this, and whilst it’s still fairly new, many brands are starting to include it in their products.
Betaine Anhydrous – 3000mg
Betaine Anhydrous is another ingredient used in pre-workouts to reduce fatigue. However, studies have still not proven this makes a distinguishable difference.
2000mg is the dosage most pre-workouts will contain, and the V2 formula includes an extra 500mg than the original formula.
Beet Root Extract (Beta Vulgaris) – 2000mg
Beet Root Extract has been proven to increase nitric oxide levels and help more blood flow to muscles. Whilst most nearly all pre-workouts use less than the optimal amount, 2000mg is very well dosed.
Most pre-workouts won’t even use 500mg.
Nitrosigine – 1500mg
Nitrosigine is a patented complex of bonded arginine silicate. It’s has over 30 studies done to test and prove both its safety and efficacy. Nitrosigine has been shown to promote nitric oxide production and improve blood flow, focus, and energy.
L-Tyrosine – 1500mg
L-Tyrosine is often used as somewhat of a counter-balance to negate the side effects of high caffeine content. It helps balance your mood and may provide a cognitive boost.
1000mg is an ideal dosage, and Huge Nutrition has upped it to 1500mg in Pump Serum V2.
Agmatine Sulfate – 1250mg
Agmatine Sulfate is another ingredient that still needs to be thoroughly researched. However, the theory is that it can help boost nitric oxide in the body and increase muscular pumps.
Dosages can range up to 3.5g; however, 1000mg to 1500mg is considered a good and safe dosage.
Pomegranate Extract (Punica Granatum) – 1000mg
Research suggests that pomegranate extract may help provide nitric oxide levels and help deliver additional oxygen to the muscles during intense exercise.
Choline (as Choline Bitartrate) – 980mg
Choline is widely used as a nootropic and may help to improve focus and concentration. This is one of the ingredients that could be considered essential in a stimulant-free pre-workout, as it delivers the focus element without the stimulant like side-effects.
VasoDrive-AP (Casein Hydrolysate) – 254mg
Vaso-Drive-AP helps to improve nitric oxide and lower blood pressure. Any pre-workout I’ve ever taken that includes this has always provided incredible pumps in the gym.
Pink Himalayan Sea Salt – 197mg
Himalayan Pink Salt contains electrolytes, and salt, in general, helps you to retain water, which can help boost strength and pumps in the gym.
Huperzine A 1% (Huperzia Serrata Leaf Extract) – 20mg
Huperzine A is another ingredient that acts as a cognitive enhancer, and a dosage of 20mg is quite common. Since this is a stimulant-free pre-workout, we believe Huge Nutrition has used a very small dosage of 200mcg to get rid of that stimulant element.
BioPerine – 5mg
BioPerine is the last of the new ingredients inside Pump Serum V2. It’s a patented form of black pepper extract and is used to help aid the absorption of other ingredients.
Pump Serum Flavor Options
The original formula of Pump Serum was only available in one flavor, Strawberry Watermelon.
Pump Serum V2 is available in two new flavors, Jungle Juice and Strawberry Mojito.
Whilst we’re personally not huge fans of a strawberry element in supplements, Jungle Juice is a winner in my book.
Price
The price for a tub of Pump Serum is $54.95, which is $20.00 more expensive than the original formula. Given the fact it contains double the serving content, the overall value has improved slightly.
Not too bad a price for a stimulant-free pre-workout.
Where can I buy Pump Serum?
You can buy a tub of Pump Serum on the Huge Supplements website for $54.95.
FAQ
Here are some frequently asked questions about the product:
Q: How Can I Use Pump Serum?
Mix one scoop of Pump Serum with 8 to 12 fl oz of water and take it about 30 minutes before exercise.
Q: Can I Stack Pump Serum With Another Product?
Huge Nutrition states that you can stack Pump Serum with several of their other products; however, it’s optional and not a necessity. They recommend stacking Pump Serum with Arachidone, Huge BCAA, Magnify, or Wrecked.
They also sell several stacks on their website that include Pump Serum.
Summary
So, how good is Pump Serum V2?
In our personal opinion, Huge Nutrition already did an excellent job in producing a stimulant-free pre-workout, and the new formula goes above and beyond.
The addition of L-citrulline, NitroSigine, and BioPerine and increased dosages of many other ingredients really help push the formula to the top of the list.
Whilst we prefer to use stimulant-based pre-workout formulas, we think this formula is perfect for anybody looking to see great pumps in the gym and reduce fatigue without bouncing all over the place.
Quite frankly, I don’t think you’ll find a better-dosed stimulant-free pre-workout on the market. Of course, that’s just my opinion.
