What Is Test Infusion?

Test Infusion an American-made sports nutritional supplement that provides testosterone boosters and increases nitric oxide metabolization. This supplement reportedly provides an increase in energy, strength, and stamina, and its effects are magnified by combining with regular, vigorous exercise. The amino acids in this supplement work in multiple ways to positively affect athletic improvement, and the testosterone boosters encourage an increase in muscle mass.

Users are instructed to take this supplement once every day, preferably with a healthy meal. Athletes should take two capsules shortly before working out, which gives the user time to digest the supplement and begin to absorb the nutrients. Regular users report that they felt some of the effects right away, including an increase in energy and stamina, but saw greater results after three months of use in conjunction with strenuous exercise.

Individuals who visit the Test Infusion website have the opportunity to try this supplement by signing up for a free, 30-Day supply for less than six dollars. According to online reports, customers are then automatically enrolled in a subscription for the supplement, which usually costs $49.97 plus $7.99 shipping and handling per bottle. Customers are encouraged to reach out to Enutra, the manufacture of this supplement, with any questions about this subscription or about the supplement itself



The manufacturer or Test Infusion in Enutra, an American limited liability corporation that is located in Mesa, Arizona. Enutra makes a number of different supplement, as well as other products that relate to health, beauty, and fitness, all of which are available through their website but not in retail locations. Their website does not report any information about the history of this company, but since it is located in the United States, customers can feel confident in the safety of the products that it makes. All of its products are produced under the purview of the Food and Drug Administration (FDA), which means that the ingredients are all safe for use by healthy adults, but there is no evidence that their facilities have ever been inspected by independent third-party agencies. The Neutra website does provide a number of methods of contact for customers who have questions or concerns about their products or services, including a contactform, email address, and Arizona-based phone number.

Enutra is featured on the Better Business Bureau website, and although it is not a member of the organization, this alone should not be held against the company. However, it does have a very low rating on the sight, largely because of complaints about their automatic payment subscription service, which customers must opt out of instead of opting in to. There are also concerns that the customer service representatives at Enutra are difficult to reach, although the website does not only list email and mailing addresses but also a business phone number. Although the website for Enutra has links to various social media sites, including Facebook, Twitter, Google Plus, and Instagram, it appears that none of those links are connected to actual accounts, making it more difficult to connect with the company online.


How Test Infusion Works?

Users are instructed to take two capsules of Test Infusion each day, preferably with a meal that contains healthy proteins and carbohydrates, shortly before working out vigorously. The testosterone boosters and other effects of the ingredients work together to increase and improve athletic performance. In turn, users work out more frequently and harder, which magnifies the effects. Users report feeling the effects of this supplement right away, so people can judge their efficacy soon after starting them. However, the full of effects of using Vitroin, especially the gains in muscle and strength, are often not seen until after three months of regular use.

This supplement is made of all natural, plant-based ingredients, extracted and concentrated into capsule form. Two of the ingredients, AAKG and OKG, are used in many bodybuilding supplements, as they have been proven to affect nitric oxide metabolism and other biological mechanisms that increase strength and stamina. These are supplemented with L-GKG and A-KIC, which have been shown to improve athletic performance, allowing athletes to work out harder and more often. Over time, users report an increase in muscle mass, along with fat loss and more energy, thanks to this supplement when paired with exercise.


Ingredients of Test Infusion

Test Infusion is made from four key ingredients, which are touted as natural testosterone boosters, working to increase an athlete’s strength and stamina. The first is Arginine alpha-ketoglutarate, or AAKG, an ingredient that is known to many in the bodybuilding community. It has been the shown to affect the metabolism of nitric oxide when combined with exercise, as reported in the International Journal of Sports Nutrition and Exercise Metabolism. The second is Ornithine Alpha-Ketoglutarate, or OKG, which is also common in popular bodybuilding supplements. OKG effects amino acid synthesis and protein production, and its effects have been reported by the University of Michigan Health SYstem.

The third ingredient of this supplement is L-glutamine Alpha-ketoglutarate, or L-GKG, which reportedly helps users build muscle and improves blood flow, which speeds healing. The final ingredient is Arginine-ketoisocaproate, or A-KIC, which boosts nitric oxide and improves athletic performance. These amino acids and testosterone boosters work together to help athletes gain muscle, work out harder and more frequently, and get stronger with regular exercise.



One of the greatest advantages of Test Infusion is that it is easy for people to use. Unlike some testosterone boosters, users do not need to mix powder into drinks or to take multiple supplements at various times throughout the day, as athletes are instructed to simply take two capsules every day, shortly before working out. Users can take this supplement at any time, and it is beneficial during all phases of the bodybuilding cycle.

Another advantage of this supplement is that its ingredients are all natural and are derived from organic plant sources. All of the ingredients are well known amino acids, which occur naturally in various herbs and other plants. These are extracted using sophisticated, proven techniques, and are made available in capsule form for convenience and ease.

Finally, the greatest advantage of this product is the low cost initial trial, which customers can order by visiting the website and filling out the order form. For less than six dollars, customers can receive a 30-Day trial of this supplement, which is 60 capsules. Although some of the effects of the supplement won’t be fully felt until after a few months of use, individuals report that they were able to tell if it work work for them within a couple of weeks of use, which gives them enough time to cancel before the automatic subscription kicks in.



The Test Infusion website does not claim that its product holds any mainstream certification, such as NSL or GMP, but this does not mean that it is unregulated. It may simply mean that the product is too new to have yet received any certifications, or that the website is incomplete. The manufacturer of this product is located in the United States, which means its production is regulated by the U.S. Food and Drug Administration (FDA), which guarantees its safety. Customers can feel confident that the ingredients on the label are all proven to be safe for use by healthy adults, and that supplement is produced in compliance with all workplace regulations.

The best guarantee of Test Infusion’s quality and effectiveness is the fact that the manufacturer is willing to provide a 30-Day trial of this supplement for such a low initial cost. As long as customers choose to unenroll from the automatic subscription service, they can try out this supplement for less than six dollars for 60 capsules. Although it may take a few months to see full results, customers should be able to feel some effects right away, which allows them an opportunity to return the product if it does not meet their needs. Customers can also read the many online reviews and discussions of this supplement to judge its efficacy and usefulness in advance. Although this supplement has received mixed reviews from previous users, customers can use the free trial to make their own decision.



I really like how easy this supplement is to use. I just take two capsules every day a little while before I work out and I can totally feel the difference. I have more energy and that makes me want to work out even harder.

– Ted K., Phoenix, AZ

I’m getting older and have been feeling like I can’t work out as hard as I want to. Since I started taking Test Infusion I can feel totally myself getting stronger and healthier. My stamina has also improved, which helps me in all areas of life, especially at the gym.

– Bob S., Nashville, TN

This stuff is pretty good. I got my free trial a couple weeks ago and it feels like it’s starting to make a difference. I can feel some more energy, but I don’t know if I’m going to keep taking it. It is easy to use too.

– Matt D., Seattle, WA

Got this a few days ago and started taking it. I haven’t seen the results yet, but I know that can take a few months so I’m trying to be patient. It sometimes seems like I have more energy when I work out so that’s awesome. I’m looking forward to getting more stamina too.

– Peter S., Columbus, IN
