What Is NO Xtreme?

NO Xtreme is a pre-workout supplement that combines three amino acids and caffeine to increase nitric oxide production and energy levels before exercise. This supplement is made in America by Zoop Industries, CC, LLC, a company that is located in South Africa. NO Xtreme is not available in retail stores or major online distributors, although this policy may change in the future, and it is only available for delivery to South African addresses.

The three amino acids in this supplement, L-Arginine Alpha-Ketoglutarate, Citrulline Malate, and L-Norvaline, all work to improve nitric oxide levels, which act as vasodilators. This improves blood flow and circulation as well as mental focus.

This supplement also contains 100mg of caffeine, which provides an immediate energy boost and improves stamina and metabolism.

Currently, this supplement is available online through a risk-free trial offer and automatic EZ Refill Program. Customers will be only charged a small shipping and handling fee at first, but will be charged the full price 18 days after the order was placed unless the customer cancels the auto-subscription. This subscription will then charge the customer for another bottle every 30 days, although the customer can email the customer service department to cancel the EZ Refill Program at any time.



NO Xtreme is manufactured by Zoop Industries, CC a supplement producer from Cape Town, South Africa. This is where customers can find both its corporate and South Africa-based return mailing address. There is also another United States-based mailing address for returns made in the U.S., which is located in Henderson, Nevada, USA. However, the current website only ships to South African addresses, so customers in other countries will need to find an alternative distributor.

There is very little corporate information available on Zoop Industries, CC and no public social media profiles on Facebook, Twitter, Instagram, or Pinterest. There is a manufacturer of motorcycle accessories that shares the name Zoop Industries and is also located in Cape Town, South Africa, but it is unclear if they are the same corporation. There are online reviews of NO Xtreme that reference Zoop Industries, but these do not provide any further corporate information. The Better Business Bureau (BBB) has no record of this corporation and has no registered complaints against it. Customers who wish to inquire about Zoop Industries can use the customer service email address that is provided on their website.


How NO Xtreme Works?

Like other pre-workout supplements, No Xtreme should be taken about 20 minutes before working out, which gives the ingredients in the formula to be digested and absorbed. The caffeine in this supplement will provide an immediate energy boost, as well as speed up metabolism and help athletes focus on their workout. The amino acids L-Arginine Alpha-Ketoglutarate (AAKG), Citrulline Malate, and L-Norvaline, all provide an immediate nitric oxide boost as well. These vasodilators increase blood flow and decrease blood pressure, flooding muscles with a greater supply of protein and energy. Like caffeine, L-Arginine Alpha-Ketoglutarate has also been shown to increase mental focus and concentration, so athletes can work out better and more efficiently for fast results.

Users should feel the effects of this supplement after just one serving, so they can quickly judge whether it fits their athletic needs. When it is used regularly, and combined with regular exercise and a healthy diet, users should see the results within three weeks. This supplement is particularly appropriate for bodybuilders in the cutting phase of their cycle, as it speeds up fat loss and supports exercise with more energy and nitric oxide. If users are sensitive to caffeine, are under the age of 18, or suffer from any underlying health problems, this supplement may not be appropriate.


Ingredients of NO Xtreme

NO Xtreme contains four active ingredients that work to boost energy and nitric oxide levels before a workout, three of which are amino acids. This supplement contains 500 milligrams of L-Arginine Alpha-ketoglutarate, or AAKG, one of the most powerful nitric oxide boosters available. This vasodilator increases nitric oxide metabolization, leading to increased blood flow to muscles and even better mental focus. The effects of the L-Arginine Alpha-ketoglutarate are magnified by an additional 350 milligrams of Citrulline Malate. This ingredient has been proven to increase NO levels and ATP production, especially when used in conjunction with anaerobic exercise like weightlifting. Finally, this supplement includes 50 milligrams of L-Norvaline, which improves circulation and also increases nitric oxide production.

These three amino acids are complemented by 100 milligrams of caffeine, a common ingredient in pre-workout supplements that provides an immediate energy boost equivalent to a small cup of coffee. Caffeine is more than just a regular energy booster, though; it has also been scientifically proven to positively affect metabolism and increases physical stamina during exercise. The inactive ingredients in this supplement are Rice Flour, Gelatin, Magnesium Stearate, and Silicon Dioxide. This supplement has zero calories, making it appropriate for athletes looking to lose weight, and is gluten and dairy free, but not vegan or kosher.



One advantage of NO Xtreme is that it all of its listed ingredients are backed by published scientific studies that can easily be read online. Athletes know exactly what they’re getting with this formula, and can research the quantity and quality of these ingredients themselves. All four of the ingredients included in this supplement have been proven effective for increasing energy or vasodilation in healthy adults.

For athletes who are looking to lose fat, this supplement is appropriate for all low-calorie or otherwise restricted diets. This supplement contains zero calories, no wheat, soy, nuts, or dairy. And, since its ingredients work to improve the user’s metabolism, it may also be effective for speeding up weight loss.

Finally, this supplement has the advantage of being currently available as a risk-free trial offer. Rather than pay the full price of $80.24 per bottle straightaway, customers can try it for 2 weeks and cancel the automatic subscription before being charged the full price. Customers who cancel the automatic monthly subscription can keep the original bottle at no extra cost, making this an affordable way to preview NO Xtreme.



According to the website, NO Xtreme is made in the United States of America, which means its safety is certified by American manufacturing laws. This dietary supplement’s production is regulated by the Food and Drug Administration and certified as safe for consumption by healthy adults. Its manufacturing facilities are regulated by the Occupational Safety and Health Administration, which guarantees workplace safety and high manufacturing standards.

This supplement has also been certified as safe for export to and sale in South Africa. Although there is no clear international equivalent to the FDA, supplements in South Africa are regulated by the Foodstuff Cosmetics Disinfectants Act No. 54 of 1972. This guarantees that the product is healthful for human consumption and made of safe ingredients.

Finally, the claims made by this supplement are backed up by their risk-free trial offer, which allows customers to sample the product for up to 18 days. If their EZ Refill subscription is canceled within 18 days of the initial order, customers can keep the supplement at no additional cost. Since this product claims to work quickly, users will know well in advance of the deadline whether or not the supplement is effective.



I’ve tried a lot of pre-workout supplements so I know what I’m talking about, and this is the real deal. I could feel it right away which is so important. Who wants to wait a week before they see results? With NO Xtreme I immediately got more energy and hit the weights harder than usual. I’m going to keep taking this because I love how fast it works!

– Jim H., 37, Cape Town, South Africa

I used to be in great shape, but since I hit middle age I’ve gotten kind of fat and lazy. I knew I needed to make a change, so I ordered this free trial. I’m glad I did! It really kicked my butt into gear and got me back to the gym. I’ve been working out every day for a week now and feel amazing. Finally,something that really works!

– Chip L., 22, Johannesburg, South Africa

It’s only been about a week since I started taking NO Xtreme every day, but so far so good. I can feel the caffeine go to work right away, but it’s not so much that I feel jittery. And I don’t crash after my workout, though I do get pretty tired. I think if I kept using this I’d probably add something else after my workout to help with recovery, but this stuff works well enough to get me started.

– Rick B., 26, Port Elizabeth, South Africa

I do like this supplement, though I don’t know if I like it enough to keep taking it for a long time. It definitely works fast, and I got my shipment just four days after I ordered it. I like the burst of energy from all the amino acids and caffeine, and I like how easy it is to take. I’ll probably try it for another couple of days before I make any commitment to the subscription, though.

– Jerome D., 29, Cape Town, South Africa


Awards & Media Coverage

There has been very little coverage of either NO Xtreme or of its manufacturer, Zoop Industries, CC, either online or in print media. There are a few reviews of the product on websites dedicated to supplement reviews, but it is unclear if these reviews are based on personal experience or simply on the product’s reputation. There are also some blog postings that claim to be from athletes who have used this supplement and praise it. While there is more available information about Zoop Industries, this coverage is mostly about their motorcycle accessories and other business dealings, with little information about their supplement production or sales.

The ingredients in this supplement, however, have received a great deal of media attention, from online sources, mainstream print media, and published scientific papers. For example, the physical benefits of caffeine have been covered in The New York Times, The Washington Post, and USA Today. Its benefits have also been the subject of papers published in the 2001 journal of Sports Medicine, a 2003 edition of Current Sports Medicine Reports, and a 1994 paper in the Canadian Journal of Applied Physiology. The effects of L-Arginine Alpha-Ketoglutarate have been reported on by Men’s Fitness, the Huffington Post, and Shape magazine, among others. And the benefits of Citrulline have been recently covered by Science Daily, The Standard, and Medicine Daily.


Money-back Guarantee

Although there is no standardized money-back guarantee from Zoop Industries, customers who wish to cancel the monthly subscription service and return this supplement can do so. They are instructed to first email the customer service department and request a Return Merchandise Authorization (RMA) number, which is essential for all refunds and returns. This number must be clearly written on the outside of the package along with the customer’s’ name and return mailing address. As stated in their Terms and Conditions, Zoop Industries cannot accept any returns that are lacking this RMA number. Returned packages must be postmarked within 5 days of the customer’s receipt of the RMA number.

Customers have 30 days from the date of their initial order to make any returns. They are responsible for the cost of shipping back any unused portion of the supplement, including bottles that have already been opened. Customers may be charged an additional 20% restocking fee for their returns. To avoid further monthly charges from the EZ Refill Program, customers must email the customer service department before another shipment is sent out.



After an order is placed, the shipment is sent out within one day business day, excluding weekends and holidays. Delivery takes an estimated 3-5 business days, although Zoop Industries is not responsible for any delays and can not be held liable for loss or damage that occurs during transit. Customers who do not receive their shipment of NO Xtreme within one week of ordering should email the customer service department right away to ensure that it has been sent. Deliveries are sent out using standard South African Post Office (SAPO) delivery service, and shipments may be trackable using their online tracking service.

The cost of shipping and handling for a single bottle of this supplement is $5.12, which is a non-refundable cost. For customers who order the risk-free trial bottle, they will only be charged this small amount for delivery. Customers who continue to receive monthly shipments from the EZ Refill Program will be charged an additional $5.12 on top of the full price each month. For returns or exchanges, customers are responsible for the cost of shipping back the returned product. Since Zoop Industries is not responsible for returns that are lost in transit, customers may want to use a certified tracking service for any shipments that they send back.


Customer Support

For questions, problems, or to cancel the automatic monthly subscription, customers should use the customer service email address that is provided on the NO Xtreme website. It is unclear how frequently this email address is checked, so customers should allow at least 24 hours for a response. There is no customer service phone number available, so customers should use this email address for all communication with Zoop Industries CC about their products.

For returns, customers should first use the aforementioned email address to get an RMA number, and then use one of the return addresses listed on the website. Depending on the customer’s geographic location, they will be instructed to return their merchandise to either an address in Cape Town, South Africa or Henderson, Nevada, in the United States. These addresses should not be used for standard communication, as they are not reliable checked by employees of Zoop Industries.

Answers to many of the standard customer inquiries can be found on the website’s Terms and Conditions page, which is readily available at the bottom of the website. This explains all of the company’s policies about ordering, billing, shipment, returns, refunds, and the automatic subscription program. It also details all of the legal protections and procedures, including the corporate stance on privacy, liability, and customer communications.


Safe & Secure Checkout

The checkout form on the NO Xtreme website uses all of the standard security procedures to protect customers’ personal and financial information. Specifically, it uses a 128-bit Secure Socket Layer (SSL) encryption, which is the standard encryption for online merchants. The connection to this payment page is also protected by a valid, up-to-date server certificate. Finally, since customers are obligated to pay for their trial with a major credit card, they are protected by the policies of the credit card companies, which guard against identity theft, fraud, and other malfeasance.

Customers should also review the Privacy Policy for Zoop Industries, which is clearly available as a link on the website. This policy states that, by providing their phone number to Zoop Industries, customers agree to be contacted on the phone in the future, even if they are also on dedicated do-not-call lists. The website also uses cookies and web beacons to track and record user data, and also records IP addresses and logs their usage time. However, Zoop Industries CC assures customers that it does not sell or share the personal data they have been collected with any third-parties.


Pricing & Free Trial

The initial cost to receive a risk-free sample of NO Xtreme is $5.12, which covers just the cost of shipping and handling. Customers who cancel the EZ Refill Program within 18 days of their order can then keep that original bottle at no additional cost. If a customer does not cancel this automatic subscription, he will be charged an additional $80.24 to keep that bottle.

The EZ Refill automatic subscription program will then charge customers an additional $80.24 every 30 days in perpetuity until it is canceled. For this price, plus an additional $5.12 for shipping and handling customers will receive a 30-day supply of NO Xtreme. One bottle of this supplement contains 60 capsules, so the price works out to approximately $1.33 per capsule.

If customers wish to return this supplement, and if Zoop Industries CC determines that they are due a refund, customers are responsible for the cost of shipping their package back to the company. The initial cost of shipping and handling is not refundable. Zoop Industries also retains the right to increase the price of this supplement at any time, although customers will have the option to cancel any orders at the increase rate if they do not wish to pay it.
