VasoMax takes pumps to a whole new level – when it comes to innovative pump formulas, they aren’t messing around!.
VasoMax features full disclosure labeling, there’s no prop blends here!
It features GlycerPump 65% glycerol powder and VasoMax was one of the first formulas to use this version of glycerol, which is a superior form of glycerol that absorbs better than any other type, mixes easily, and won’t clump like other glycerol powders.
GlycerPump is not a nitric oxide booster, rather, it pulls water into the muscles for a dramatic cell volume effect, stay well-hydrated for max effect.
Next up is a relatively new ingredient, MaxNOx, also known as potassium nitrate.
This is well-dosed at 810 mg and this nitrate has become known as a potent N.O. booster.
VasoMax uses the patented version, and in fact is using premium quality ingredients throughout the formula.
The next ingredient is Rutaecarpine, another uncommon ingredient that originates from the Evodia Rutaecarpa plant, which has a long history of use in traditional Chinese medicine.
It also supports increased N.O. production, further enhancing nitric oxide-based pumps.
The final pump ingredient is GNSO, another new ingredient, also known as S-Nitrosoglutathione.
VasoMax sets itself apart from other pump formulas with a well-dosed focus complex that includes Alpha-GPC, sceletium tortuosum and huperzine A.
Alpha GPC is the most absorbable form of choline and essential for the fabled mind-muscle connection.
Sceletium Tortuosum is an herb that combats stress and enhances focus.
Finally, we have huperzine A which is similar to choline in its effects.
VasoMax is a good value with 25 servings and 1 scoop per serving, and it’s one of the strongest and most innovative pump formulas you will find.
While it’s primarily a nitric oxide-based pump formula, we like the fact that it covers water based pumps and provides a unique twist with the addition of a mental performance complex.
8g Citrulline Malate, 4g GlycerPump, 1g Agmatine, 1g Super Spinach, 250mg PegaPump
NovaPump came out as one of an innovative formula that uses ingredients that hasn't been used in a N.O. booster before.
PegaPump and Super Spinach are both unusual and uncommon compounds to see.
These two ingredients have shown promising results for increasing vasorelaxation, nutrient delivery and everlasting pumps (over 24 hours!).
PegaPump is from a plant called Syrian Rue, and from that plan there are alkaloids that increase relaxation in veins.
These alkaloids are collected into an extract, PegaPump.
There needs to be more research done on this compound but so far we’re excited to see more of this in nitric oxide supplements.
The 4g of GlycerPump is way above average in dosing from most, if not all competitors.
It’s the superior form of Glycerol, and it’ll increase muscle size by shuttling more water into muscle cells.
This means you need to ensure your water intake is sufficient.
To top it off, agmatine and citrulline will increase blood flow and pumps are going to be enhanced all day long.
Novapump has set the bar, and so far the hyped up PegaPump seems to be living up to its reputation with reviewers praising for having amazing, all day pumps.
On a healthy note, Super Spanish will help lower blood pressure, helping combat against the side effects from stimulants like DMAA and caffeine.
NovaPump is all around one of the best stim-free pump pre workouts we’ve seen so far.
Bare Knuckle packs quite a formula with 8g L-Citrulline, 3g Arginine Nitrate, 1g Lion's Mane, 2g L-Tyrosine, 1.5g Agmatine Sulfate, 600mg Alpha GPC, this is the most effective stim-free pre workout for pumps and focus.

Hooligan is a strong pump supplement that has surprised us with a potent formula.
Apollon Nutrition consistently releases aggressive and hard hitting pre workouts that are improving with better ingredients and formulas.
Hooligan is a stim-free pump supplement but it’s a strong one that you won’t see anything like it anywhere else.
It’s ingredients help build muscle, increase muscle size and enhance energy.
Covering your basic vitamins, Hooligan contains every B vitamin, including B3, B6, B12, B5 and even folic acid.
It starts off strong with 8g citrulline, continues with the betaine anhydrous at 2.5g.
Both of these ingredients are excellent for pumps and size.
And the nice thing is that the citrulline is the pure stuff, not the citrulline malate.
If it was malate, then it would be something like 16g(!).
And for keeping the nitric oxide levels up, we have 1.5g agmatine, a powerful defensive N.O. enhancer.
It doesn't end there though.
There's 3g arginine nitrate, twice the average dose, so at 3g it should make for some interesting pumps with performance enhancing benefits.
With a non-stim product, comes the need for enhancing that mind to muscle connection, which is why Apollon has included 600mg Alpha GPC.
That'll help with choline and it will help strengthen that mind to muscle connection.
Although Hooligan is a non-stim, it still has energizing boosting ingredients and they are generously dosed, at 2g for tyrosine and 1g lions mane.
Both of these ingredients are beneficial for boosting focus and energy without being stimulants.
Whether you're cycling off caffeine or stacking with another stim-based pre workout, Hooligan Bare Knuckle is a potent pump supplement to use.

Nitric oxide is a molecule that our body produces to help its 50 trillion cells communicate with each other.
This communication happens through the transmission of signals in virtually every bodily function, including the functions of the immune, nervous, and cardiovascular systems.
Nitric oxide has been shown to be important in several physiological processes, including angiogenesis (growth of new blood vessels), neurotransmission (communication between nerve cells), and immune response.
For bodybuilding, nitric oxide is crucial as it plays a key role in cardiovascular health and muscle building.
It does this by relaxing and dilating blood vessels, thereby improving blood flow to the muscles during workouts.
This improved blood flow means that more oxygen and nutrients can be delivered to working muscles, enhancing workout performance and leading to better muscle growth.
Here are some of the key benefits of nitric oxide supplements:
1. Enhanced Muscle Pumps: Nitric oxide supplements are known for their ability to enhance muscle pumps during workouts. They do this by increasing blood flow to the muscles, which allows for better delivery of oxygen and nutrients. This not only leads to more noticeable muscle pumps but also enhances muscle growth and recovery.
2. Improved Workout Performance: By increasing blood flow, nitric oxide supplements can help improve workout performance. They allow for better oxygen and nutrient delivery to working muscles, which can lead to increased strength and endurance. This means you can push harder and for longer during your workouts.
3. Faster Recovery: Improved blood flow also means faster removal of waste products from the muscles, such as lactic acid, which can accumulate during intense exercise and cause muscle fatigue. By helping to remove these waste products more efficiently, nitric oxide supplements can help speed up recovery times and reduce muscle soreness.
4. Lower Blood Pressure: Nitric oxide is a vasodilator, meaning it relaxes and widens blood vessels. This can lead to a reduction in blood pressure, which is beneficial for cardiovascular health.
5. Enhanced Cognitive Function: Some research suggests that nitric oxide can enhance cognitive function. It plays a key role in neurotransmission - the process by which signals are sent between nerve cells. This can lead to improvements in memory, focus, and learning.
6. Improved Sexual Health: Due to its ability to increase blood flow, nitric oxide has been found to improve sexual health. It's often used as a natural remedy for erectile dysfunction and can enhance sexual performance.
It's important to note that while nitric oxide supplements offer numerous benefits, they should be used as part of a balanced diet and regular exercise routine.
Always consult with a healthcare professional before using any new supplement.
When it comes to choosing a muscle pump supplement, there are several key factors to consider.
These factors will ensure that you select a product that not only delivers on its promise of enhanced muscle pumps but also aligns with your individual fitness goals and needs.
1. Active Ingredients: The effectiveness of a muscle pump supplement largely depends on its active ingredients.
Look for ingredients that are known to increase nitric oxide production, such as L-Citrulline, Arginine, and Beet Root Extract.
These ingredients work by dilating blood vessels, which allows for increased blood flow to the muscles during workouts.
2. Dosage: The dosage of the active ingredients is also crucial. Make sure that the supplement provides an effective dose of each ingredient. Under-dosed ingredients may not provide the desired effects.
3. Stimulant-Free: Many muscle pump supplements are stimulant-free, which makes them a great option for those who are sensitive to stimulants or who prefer to avoid them. Stimulant-free supplements can also be taken alongside pre-workouts for an added boost.
4. Brand Reputation: The reputation of the brand can give you an idea of the quality of their products. Look for brands that are known for their high-quality ingredients and manufacturing practices.
5. Reviews and Testimonials: Reviews and testimonials from other users can provide valuable insight into the effectiveness of the supplement. However, keep in mind that individual results can vary.
6. Price: While it's not always the case, often you get what you pay for. Cheaper supplements may use lower-quality ingredients or less effective dosages. However, this doesn't mean you need to go for the most expensive option. Find a supplement that offers a good balance of quality and cost.
7. Taste: If you're going to be taking a supplement regularly, it's important that you enjoy the taste. Look for supplements that have positive reviews regarding their flavor profiles.
Remember, while muscle pump supplements can enhance your workouts, they are not a magic solution. They should be used in conjunction with a balanced diet, regular exercise, and adequate rest. Always consult with a healthcare professional before starting any new supplement regimen.
Agmatine Sulfate: As mentioned earlier, this compound derived from the amino acid L-arginine regulates nitric oxide synthase to increase muscle blood flow. It also enhances cognitive focus and provides pain relief and neuroprotective benefits.
Citrulline (L-Citrulline & Citrulline Malate): These forms of citrulline are proven to decrease fatigue and muscle soreness while increasing nitric oxide, blood flow, and arginine in the blood. Citrulline also improves pumps and vascularity and facilitates post-workout recovery. Read about the difference between citrulline vs citrulline malate.
Nitrosigine®: This supplement, also known as arginine inositol silicate, is scientifically proven to increase nitric oxide and silicon blood levels pre-, intra-, and post-workout. It increases vasodilation, arginine blood levels, and maximum blood flow, and strengthens arterial walls. See our Nitrosigine guide.
HydroMax Glycerol: This compound offers the most concentrated and pure powder glycerol on the market and mixes easier than GMS. Consuming a minimum of one gram per kilogram of body weight prior to your workout will prevent dehydration, improve exercise performance, and significantly increase muscular pumps. The guide on Hydromax can be found here.
Betaine (Nitrate & Anhydrous): Betaine plays crucial roles in liver function, carnitine production, cellular reproduction, and preventing the buildup of amino acid homocysteine in the body. Daily oral doses of 500mg to 3,000mg can increase anaerobic running capacity, muscular endurance, and blood flow.
Beet Root (Beta Vulgaris): Beetroot is rich in nitrates, promoting whole-body blood flow and many slow or reverse the stiffening of arteries. In addition to being high in nitrates, beetroot contains high levels of folic acid, fiber, manganese, and potassium.
L-Norvaline: This unbranched form of the essential branched-chain amino acid (BCAA) L-valine increases the body's natural upper limit of nitric oxide production by up to 55%, which as a result increases nutrient transport to the blood, muscular pumps, and vascularity.
Pomegranate Extract: Pomegranates have potent antiviral, antibacterial, and antioxidant properties. A handful of human studies suggest that pomegranates increase whole-body blood flow and prevent the thickening and stiffening of arteries.
Pycnogenol: Also known as pine bark extract, contains high amounts of procyanidins which increases nitric oxide synthase, dilates blood vessels, and offers potent antioxidant properties when dosed daily between 40mg and 200mg.
Resveratrol: A heart-healthy polyphenol found in the red grape skins and wine, naturally relaxes the blood vessels, improves circulation, and increases vascularity when used at oral doses of 5 to 25mg of trans-resveratrol.
