If you still cannot locate it, contact our support team at info@4endurance.co.uk, and we’ll be happy to help you resolve the issue.

No, we don’t offer a satisfaction guarantee or trial period. Nutrition products affect everyone differently, and results can vary widely depending on individual physiology, training load, and usage. For safety and quality reasons, opened or used nutrition products cannot be returned.

At 4Endurance, our mission is to make sure nutrition costs never stand in the way of an athlete reaching their goals. We keep prices low through efficient in-house production, minimal packaging, and lower margins, without compromising quality.

Check our product guides and blog for advice on which nutrition products best suit your needs. You can also contact our customer care team for personalised advice.

Unlike brands that create nutrition for the general public, 4Endurance focuses exclusively on endurance athletes. Every product is developed with real training and racing demands in mind, with clear dosing, high-quality ingredients, and formulations that are easy to use and combine.

Yes, all 4Endurance products undergo strict quality control. They are tested for banned substances and comply with WADA regulations, with strict quality and safety controls applied throughout production.

Many of our products are vegan, gluten-free, and allergen-conscious. Check the product label for details.

Yes, many of our products can be combined to suit your training and recovery needs. However, not all products make sense to combine. Some products have opposing effects. For example, creatine increases water retention, while other products are designed to reduce it so using them together would be ineffective. If you’re unsure, check the product guidance or contact us for help choosing the right combination.

Yes, we guarantee that all 4Endurance products are doping-free. Each formula is thoroughly checked, ensuring that no ingredient is on WADA’s prohibited list. You can see the list here.

Storage requirements vary depending on the product. Most products should be kept in a cool, dry place, away from direct sunlight. Some products, like energy gels, are stable at room temperature and don’t require special storage. Always check the product label for any specific instructions to maintain the product’s quality and effectiveness.

Yes, all 4Endurance nutrition products have expiration or “best before” dates to ensure the formula stays effective and flavours remain at their best. For many products, the expiration date is listed on the product page under “Flavour and Expiration Date” or in the product options. You can also find the expiration date printed on the packaging.

Some 4Endurance products may cause mild side effects in certain individuals. Check the product descriptions for details on any known effects. If you have specific health concerns or conditions, it’s always best to consult your doctor before use.

In most cases, 4Endurance products can be used alongside other supplements. However, interactions may occur with certain medications or specialised supplements. If you are taking any medication or have health concerns, always consult your GP or healthcare professional before combining products.

Food supplements are generally not recommended for persons under 16 years of age. Most 4Endurance products without calories — such as capsules or zero-calorie drinks — fall into this category. Products like energy gels and drinks are classified as sports foods, not supplements, and may be suitable for minors under adult supervision. Parents should use their own judgment and consider the child’s needs and health before giving any product. If you are unsure, consult your paediatrician.

Yes! We love supporting athletes with their nutrition needs. We also sometimes provide discounts for teams, clubs, and coaches. You can apply here.
