Drugs Free Statement

As fellow athletes and believers in clean and fair sport, we take our drugs free policy very seriously. Doping undermines the integrity of sport and the ethos of fair competition. It is fundamentally contrary to the spirit of sport. HIGH5 supports the World Anti-Doping Agency’s (WADA) Code and their List of Prohibited Substances.

HIGH5 avoid any use of prohibited ingredients from the list of WADA named banned substances and further ensure that during the manufacture, packaging and transportation of the products, we are not inadvertently contaminating HIGH5 products with any prohibited substances. We have a 100% proven track record: No athlete has ever tested positive from using a HIGH5 product.

For athletes that require batch tested products,  HIGH5 products are available in our Batch Tested section from our online shop. These are tested for banned substances by LGC, a world class lab and lead the Informed-Sports program.

Below you can find more information on our commitment to drug free products and what this means.

What is the risk of supplement contamination?

There is a concern for consumers that dietary supplements found within the sports nutrition industry may be contaminated with banned substances.

The sports nutrition industry is very broad; ranging from endurance companies like HIGH5 who use basic food ingredients to enhance an individual's performance, to supplement based companies supplying an array of more unique products. 

Unfortunately, we are all grouped under the same heading, yet there is a misunderstanding of the risks of inadvertent doping for these products. There are also very different rules and practices in many countries for manufacturing and labelling of supplements.

What does HIGH5 do to minimise the risk?

Below we take a look into some of the different methods HIGH5 implement to minimise the risk of cross-contamination of banned substances throughout our supply chain.


Of course, HIGH5 products are not formulated with ingredients from the list of WADA named banned substances. But this is only where it starts.

We always take great care when choosing our suppliers and make an informed decision before using a new ingredient or supplier. We will not introduce any new ingredient that is on the WADA banned substance list. HIGH5 suppliers are selected based on supplier audit questionnaires which specifically assess the use of banned substances throughout the supply chain. We will not use any suppliers that we suspect has banned substances at any stage in their process.


HIGH5 production sites follow good manufacturing practices to minimise the risk of cross contamination of WADA banned substances. A variety of strong process controls are in place to ensure this is the case. These include goods in inspections, thorough cleaning regimes, house keeping and hygiene protocols, and excellent traceability systems.

Informed Manufacturer

The main manufacturing site for HIGH5 products, where we make our gels and powders, has been Informed Manufacturing Certified. This certification provides in-depth analysis into critical control processes. Through regular on-site inspections and manufacturing facility swabbing, Informed Manufacturer site registration helps HIGH5 identify and resolve areas of risk within the manufacturing process. Some of our suppliers also have this accreditation. For any products made on our behalf and aren’t made on an Informed Manufacturer accredited site, we have procedures in place to minimise the risk. This site registration is further complemented by specific batch testing of finished products.

Batch tested products

Whilst products are not formulated with ingredients from the WADA list of banned substances, in addition to a variety of other process controls, we understand that some athletes would still prefer to use products that have been specifically tested for WADA banned substances. We offer a selection of batch tested products via our online shop. A certificate from LGC labs is provided with these products.  If you require additional products or you live outside the UK then please contact us. You can find out more information about the testing standards from LGC below. Besides the specific batch tested products, we also do random spot tests on the whole range as part of our product testing regime.

We have been using the world-renowned sports doping control and research lab LGC (previously known as HFL) for our banned substance testing, which also runs the Informed-Sport and Informed-Choice supplement testing programmes. Supported by UK Sport, LGC offers a supplement testing service accredited to the ISO 17025 standard. This is an internationally recognised standard for analytical labs and ensures the accredited methods have been shown to be robust, capable of working to the required detection limits every time, and thus ensuring the integrity and consistency of the analytical results. ISO 17025 is the industry standard for an analytical laboratory.

Testing by a trusted lab is important to reassure us and you that HIGH5 products are free from contamination of prohibited substances. Besides the ISO 17025 standard LGC also have experience of testing within the framework of WADA. Their testing capability for supplements includes the analysis for over 146 substances that are considered prohibited in sport and substances that pose a threat in respect of product contamination. These substances include anabolic agents, stimulants, beta-2-agonists, recreational drugs and masking agents. Their highly sensitive tests can detect contamination down to 10ng/g for steroids and 100ng/g for stimulants. That’s like testing for a rain drop in an Olympic sized swimming pool. The LGC test is able to analyse all our products for relevant prohibited substances.

Why doesn't HIGH5 rely on testing alone? Download research paper

Whilst we, like any other supplier, can’t guarantee products are free from cross-contamination, we take this very seriously and have implemented a quality assurance and testing programme to minimise the risk of cross-contamination of any of our products with banned substances. However, testing a product for banned substances does not mean that the product is guaranteed drugs free. No manufacturer or quality assurance program can make this claim. Let’s look into this a bit further:

The WADA Prohibited List is not definitive. The list stipulates classes of prohibited substances, such as anabolic agents and related substances and prohibited methods only, rather than publishing a full list of substances. When analysing a supplement product for contaminants the Prohibited List is unable to act as a checklist for all prohibited substances against which products should be screened. Testing supplements cannot guard against contamination using untried, untested and unknown drugs or substances. However, LGC’s vast understanding of product testing and previous experience as a WADA accredited lab testing for banned substances means they are able to identify a list of substances for testing that maintain integrity for the tests.

Testing should be seen as an additional quality control measure rather than a guarantee of drug free products. Our approach is to minimise the risk of contamination at the source and implement a rigorous and strict manufacturing protocol. Over 20 years of manufacturing advanced sports nutrition products means HIGH5 have the experience and knowledge in place to produce safe quality products for all athletes.

We have a 100% track record

No athlete has ever tested positive from using a HIGH5 product. We have been supplying sports nutrition products to elite and professional athletes for over 20 years without an athlete testing positive from contaminated products. As a result, these methods give us the confidence to supply HIGH5 products to athletes of all levels, including World and Olympic Champions.

WADA, their code and the prohibited list

WADA’s mission is “to lead a collaborative worldwide movement for doping-free sport”. WADA was established in 1999 as an international independent agency composed and funded equally by the sport movement and governments of the world. Its key activities include scientific research, education, development of anti-doping capacities, and monitoring of the World Anti Doping Code (also known as the Code).

The Code harmonises anti-doping policies, rules and regulations within sport organisations and among public authorities around the world. Its main purpose is to protect the clean athlete. The World Anti-Doping Program is based on this fundamental and universal document. All athletes should be aware of the Code.

Want to learn more?

WADA places high importance on athlete education to prevent the intentional or unintentional use by athletes of Prohibited Substances and Prohibited Methods. We also feel this is very important and are happy to provide athletes the tools to make an informed decision before purchasing sports nutrition products. We hope the information we are providing is useful to make this decision but if you have any further questions then please get in touch with us.
