What Does Pump Serum Do?

Pump Serum is a caffeine-free pre-workout supplement from Huge Supplements. It is designed to power up your workout potential, and it achieves this by tapping into the power of nitric oxide production, vasodilation, and mental focus optimization.

At the core of Pump Serum’s functionality lies its ability to enhance nitric oxide production through a blend of ingredients including L-Citrulline, Beet Root Extract, Nitrosigine, Agmatine Sulfate and Pomegranate Extract. Nitric oxide acts as a vasodilator, expanding blood vessels and improving blood flow throughout the body. This physiological process is vital during exercise, as it delivers essential nutrients and oxygen directly to working muscles.

L-Citrulline in particular plays a pivotal role in enhancing blood flow, endurance, and muscle pump. Its reputation as a potent vasodilator is well-established in scientific research. The inclusion of Betaine Anhydrous also contributes to muscle endurance and power output, ensuring that your workouts are driven by sustained energy from non-caffeine sources. Other energy-boosting ingredients in Pump Serum include Choline, Glycerol Powder, L-Tyrosine, Casein Hydrolysate and Huperzia Serrata Leaf Extract.

For those individuals who prefer to steer clear of stimulant-laden pre-workouts yet still yearn for improved workout performance, Pump Serum certainly emerges as an attractive alternative. By replacing caffeine with other energy-inducing ingredients, it offers a clean and controlled energy boost that sidesteps the jitters and crashes associated with stimulants.

Does Pump Serum Give You Energy?

Yes, Pump Serum gives you energy. While it doesn’t contain caffeine, it contains an interesting blend of ingredients that can provide a controlled and sustainable surge of energy. Let’s take a closer look:

Betaine Anhydrous (3000mg)

One of the primary sources of energy in Pump Serum comes from Betaine Anhydrous. Derived from the amino acid glycine, betaine plays a crucial role in energy metabolism. It assists in the conversion of homocysteine to methionine, a process linked to the synthesis of creatine. Creatine is known for its ability to rapidly provide energy for short bursts of intense exercise, making betaine an indirect contributor to improved workout performance.

GlycerPump™ (65% Glycerol Powder, 3000mg)

Glycerol is another key ingredient that aids in energy enhancement. GlycerPump™, a patented form of glycerol powder, promotes muscle hydration and endurance by increasing fluid retention within muscle cells. This hydration effect can contribute to improved stamina and sustained energy levels during your workouts.

L-Tyrosine (1500mg)

L-Tyrosine, an amino acid found in Pump Serum, supports energy levels through its role in neurotransmitter production. It serves as a precursor for dopamine and norepinephrine, neurotransmitters that play a vital role in mood regulation, mental alertness, and focus. By supporting the production of these neurotransmitters, L-tyrosine contributes to sustained mental energy during your workout sessions.

VasoDrive-AP (Casein Hydrolysate, 254mg)

VasoDrive-AP is an ingredient that indirectly supports energy by enhancing blood flow. Improved blood circulation ensures that muscles receive the oxygen and nutrients they need, which can lead to increased endurance and sustained energy levels during physical activity.

The first thing that stands out in this Pump Serum review is the sheer size of its scoop. At an impressive 31g per serving it has to be one of the biggest serving sizes in its category. Just to put things into perspective, consider that a single scoop of MusclePharm’s Combat Protein Powder hovers around 36g. But that is because Pump Serum is packed with potent ingredients to give you the maximum performance gains in your workout sessions.

One thing to keep in mind is that you will need to add a good amount of water to make sure the powder dissolves properly, which is probably the biggest downside of Pump Serum.

True to its name, the pump you get from this product is amazing. To put it simply, if you’re training hard you can expect your pump to feel exactly how Arnold Schwarzenegger described them in “Pumping Iron. Another great thing about the pump-inducing effects of this pre-workout is that it really brings out the vascularity, which is awesome to see in the mirror when you’re working out.

When it comes to stim-free pre-workouts, the mental focus is also incredibly important. Pump Serum really stands out in this area. It’s great at helping you get dialled in for your workout — especially when you’re doing cardio or other types of high-intensity exercise. The focus you get from this product is remarkable and the best part is, it’s all stimulant free.

With regard to pricing, it’s true that Pump Serum carries a higher cost compared to other pre-workouts. But, the price tag is entirely justified. The amount of scientifically backed ingredients you get within this formula renders it a worthy investment in this Pump Serum review.

Pump Serum takes around 20 to 30 minutes to kick in.

Pump Serum Side Effects

Pump Serum is generally considered to be a safe supplement, incorporating a blend of scientifically backed ingredients to enhance your workout experience without compromising your health. As with any supplement, individual responses can vary, and it’s important to be aware of potential side effects.

While Pump Serum’s formula is crafted to minimize adverse reactions, some users might experience mild effects. These could include:

Gastrointestinal Sensations

Some individuals might notice mild gastrointestinal discomfort, such as bloating or stomach upset. This can be attributed to the inclusion of hygroscopic ingredients like GlycerPump™, which can attract water and temporarily affect digestion. These sensations are typically temporary and should subside as your body adjusts.

Allergic Reactions

If you have known allergies to specific ingredients present in Pump Serum, such as plant extracts or amino acids, you could potentially experience allergic reactions. Always read the ingredient list carefully and consult a healthcare professional if you have concerns.

Individual Sensitivities

As with any supplement, individual sensitivities can play a role. Some users might be more sensitive to certain ingredients, leading to sensations like a temporary increase in heart rate or mild tingling. These reactions are generally harmless and transient.


Glycerol-based ingredients like GlycerPump™ might cause increased fluid retention within muscles, which could lead to dehydration if you don’t maintain adequate hydration levels. Drinking sufficient water throughout the day can help mitigate this risk.

It’s important to note that these potential side effects are generally mild and temporary. However, if you experience any severe or persistent adverse effects, it’s recommended to discontinue use and consult a healthcare professional. Before introducing any new supplement, including Pump Serum, into your regimen, it’s wise to consult with a healthcare provider, especially if you have pre-existing health conditions, take medications, or have concerns about potential interactions.
