What Is Vigorous Muscle Maximizer?

Vigorous Muscle Maximizer is a pre workout supplement designed to help athletes increase their muscle mass. It is a supplement that provides a formula of all natural ingredients that enhance the body’s own natural processes. This may allow athletes and bodybuilders to train harder and longer with less fatigue. When combined with a proper workout routine and diet, this supplement may help to build lean muscle faster and easier than a person would be able to otherwise.



The Vigorous Muscle Maximizer is produced by the Vigorous Corporation. Unlike most supplement manufacturers, there is very little information about this company or its practices published online. The company appears to have made little effort to provide additional information about its practices, research or other products it offers. The average customer may assume that the company makes no other products.

From the Terms of Use, it is possible to discover that the company is based in Delaware, but this does not necessarily mean that their products are produced in the United States. They do not offer any contact information beyond a support email address and social media links.


How Vigorous Muscle Maximizer Works?

The Vigorous Muscle Maximizer is designed to help athletes improve their physical performance during workouts. As a pre workout supplement, it is designed to be taken directly before a workout for maximum effect. This supplement delivers a range of compounds designed to allow muscles to work longer and harder before they fatigue as well as provide them with some essential nutrients they need to grow faster and bigger. This works together with vigorous exercise and a proper diet to help stimulate muscle growth beyond what would be achieved normally.

The supplement has several groups of ingredients consisting of amino acid concentrates, natural muscle stimulants and several key vitamins and minerals. It takes a different approach to muscle building compared to most other supplements of its type by focusing on amino acids and direct extracts as opposed to a blend of herbal supplements.



The ingredients in Vigorous Muscle Maximizer are grouped into several categories based primarily on the type of ingredient and their purpose in the supplement. Despite the rather lab-heavy names in the ingredients list, the vast majority are all natural substances that can already be found in food or in the body. They have just been extracted and purified for use in supplement form.

Nitric Blast Proprietary Blend: 1975mg

This is the primary workhorse for the Vigorous Muscle Maximizer. Most of the ingredients on this list, with OKG being the exception, are various amino acid extracts. These amino acids are carefully chosen for the properties they have and the role they play in muscle gain. This combination is not the same as a protein supplement, and it will not replace the need for high-quality complete protein in the diet. In fact, it may be most beneficial to combine supplements such as this one with a protein shake or bar.


AAKG is an extract of a non-essential amino acid. Its primary role in bodybuilding is to help muscles achieve max performance by helping the body remove the ammonia waste produced by working muscles. This allows a muscle to perform longer at higher intensities before fatiguing. It also plays a role in nitric oxide production in the liver. Nitric oxide gets lots of attention in pre workout supplements because of the important role it plays in reducing muscle fatigue and increasing circulation to the muscles.


OKG is the only ingredient in this group that is not an amino acid extract. Instead, it is an ionic salt that has long been studied in the role of wound healing and disease treatment. Researchers are not exactly sure why it works, but there is a large volume of research indicating its effectiveness. It was originally used to help prevent muscle loss in patients who were prevented in one way or another from exercising properly and maintaining muscle mass.

There is evidence to show that it plays a role in protein metabolism and thus speeds the healing and recovery process of all of the body’s tissues. This works well for bodybuilding because muscle recovery and growth involves damaging the muscles through intense activity and then allowing them to heal and grow back bigger and stronger. OKG is the supplement that helps the body do exactly that.


GKG is essentially an extract of the amino acid glutamine. This amino acid supplement works as a cell volumizer. It helps muscles cells get bigger and move more proteins around. Muscle cell volume is extremely important during a workout because it plays a strong role in the amount of work the muscle can do and the amount of fatigue it will incur before failing. It also helps athletes to feel better and stronger while working out.

L-Arginine Monohydrate

L-Arginine is an amino acid commonly found in poultry, red meat and fish. It is a vital protein that plays a strong role in muscle growth and tissue synthesis. This amino acid is what provides the bulk of the material your muscles need to grow. While it can be obtained from food sources, especially if a person eats a lot of meat, it may be more advantageous for a bodybuilder to get a large supply in supplement form.


Beta-alanine is another non-essential amino acid that helps your muscles do more work. Unlike most of the other ingredients, the effects of beta-alanine are often felt as a tingle in the muscles. This tends to be more noticeable in those who have not taken a pre workout supplement before. It has been scientifically shown to act at least in part as a neurotransmitter. This means that it has a stimulating effect on the body almost like that of caffeine.

In muscles, it primarily plays a role in the synthesis of Carnosine. The presence of Carnosine in muscles is extremely important from a workout perspective. Carnosine helps muscles resist the buildup of hydrogen ions that occurs during high-intensity workouts. This rapidly leads to muscle fatigue, so Beta-Alanine plays an indirect but very important role in reducing muscle fatigue.

It is important to note, considering that Creatine is absent from the Vigorous Muscle Maximizer, that Beta-Alanine may function in largely the same role. There is a chance that it may even be one better because Creatine does not always work for everyone. That is not the case with Beta-Alanine, which has been shown effective in a wider variety of persons.

Warrior Stimulant Proprietary Blend 74mg

This stimulant blend represents one of the weaker aspects of the Vigorous Muscle Maximizer formula. Unlike most of the other ingredients, which are well understood and researched extracts, most of these stimulants are plant-based extracts with very weak research and known effectiveness in regards to sports performance or bodybuilding. This set of ingredients makes up the smallest part of the supplement.


Also known as Bitter Orange, Synephrine can be considered the most active chemical from this plant. It has been shown to be a weak stimulant that may play a role in increasing metabolism and fat burning. It is said to work similar to Ephedrine, but it is not as potent. This supplement delivers an acute dose of Synephrine that may have some effect, although the optimal dosage is usually spread across three smaller dosages a day. The scientific support for this ingredient is rather minimal. It may give noticeable increases in energy level similar to the effect of caffeine.


This is another plant extract from an evergreen tree commonly found in Africa. The plant has been used for centuries as a folk medicine. It is important to note that only one compound or part of the plant is effective. Specifically, a supplement must contain the bark of the tree or list the active chemical Yohimbine. Since Vigorous Muscle Maximizer does not specifically list Yohimbine or Yohimbe bark as the ingredient, the potency and relevance of this in the supplement is suspect. Assuming that the active compound is being used, then Yohimbe is a weak stimulant that may provide some noticeable increase in energy level. Few if any studies have shown it to be specifically effective for athletes. When combined with Synephrine or another stimulant, as it is in the Vigorous Muscle Maximizer, it may be more noticeable.


Niacin is the proper name for Vitamin B3. The B vitamins play a very important role in metabolism and energy production in the cells. Basically, more B vitamins means more energy. This is very important for athletes that need to increase their metabolism and have more energy available. The downside to having only Niacin is that the B vitamins work best when they are used together, commonly known as the B Complex. When only one vitamin is taken as a supplement, it tends to have less effectiveness.

Pre-Workout CoFactor Proprietary Blend 175mg

This is a blend of basic nutrients and amino acids. They work to compliment the other ingredients in the formula. The basic nutrients play a very minor role in the product’s effectiveness. The amino acid L-Citrulline, however, is an important addition.

Calcium Phosphate

This is essentially a calcium supplement. While it is important for athletes to maintain strong bones, a calcium supplement will have very little to no direct effect on muscles or performance unless the person taking it already has a calcium deficiency. Calcium supplements are normally used to prevent bone fractures or weakness in those at risk for deficiency. It is also noteworthy that common calcium deficiencies have little to do with calcium and instead represent a Vitamin D deficiency since that vitamin is necessary for the metabolism and use of calcium. Since this supplement does not combine calcium with vitamin D, this ingredient may have a reduced effect.

Dipotassium Phosphate

A potassium supplement is somewhat more useful than a calcium supplement because potassium plays a much stronger and more direct role in cell metabolism and energy production. It will still have a very indirect role in sports performance.


This is a non-essential amino acid that the body converts into L-Arginine. Interestingly, there are a variety of benefits to including L-Citrulline in addition to or even instead of direct amounts of L-Arginine. Some research shows that large doses of L-Arginine tend to be poorly absorbed and may have the side effect of producing diarrhea. L-Citrulline can be supplemented in high doses without this problem and may result in net higher blood concentrations of L-Arginine compared to supplementing with L-Arginine alone.

Like L-Arginine, L-Citrulline has a strong effect on the ammonia recycling process in muscles. By increasing the efficiency at which muscles can remove the buildup of ammonia, these supplements may allow the muscle to work harder before fatiguing.

Nicotinamide Adenine Dinucleotide

This chemical compound is found naturally in the body and plays a strong role in mental alertness and energy metabolism. It has a very similar role as the stimulants in this supplement but a much different method of action. It is not necessarily a stimulant, but it may provide more energy and focus for intense workouts. It is commonly used in supplement form, and it has decent research and usage support.

Glycovascularity Proprietary Blend 200mg

The ingredients here are both scientific names for basic nutrient supplements. While they are very important nutrients for health, they will likely have little to no direct impact on sports performance or bodybuilding.

Potassium Glycerophosphate

This is another version of a potassium supplement. While potassium plays a crucial role in the body, doubling up on this basic nutrient in a pre workout formula does not seem necessary.

Magnesium Glycerophosphate

This is a magnesium supplement. Magnesium is important in bone structure and health. It compliments the calcium supplement and is a common ingredient in pre workout formulas. While it can be difficult to get adequate magnesium from food, a supplement form may have some benefit.



The Vigorous Muscle Maximizer has enough quality ingredients to have some effect on workout performance and the development of lean muscle mass. It may generally be considered effective as a pre workout supplement. While many of its minor ingredients are just basic vitamin and mineral supplements, it does have a majority of highly effective ingredients with proven roles in performance and muscle building. This is especially true of the first set of ingredients that contains L-Arginine and Beta-Alanine. By giving the body a high dose of nitric oxide producing compounds, workout performance may be increased and muscle fatigue may be decreased.

The plant-based stimulants may also play a minor role in improving energy levels and alertness. Many stimulants have been shown to allow muscles to work harder for longer periods before fatiguing or to decrease the notability of fatigue.



The Vigorous Muscle Maximizer has no known or noteworthy certifications as a whole. Looking at its ingredients list, most of its ingredients are well known and understood to be effective from a health and scientific standpoint, but they do not necessarily have certifications.
