Product testing

At CLNFuel, we take testing seriously. Our most recent batch of Creatine gummies was sent to two independent laboratories, both confirming slightly more than 5g of creatine per serving.

In addition to verifying creatine content, our Creatine Berry and Boost Berry gummies have also been tested for banned substances and contaminants, making them safe for athletes and everyday users alike. We’re committed to giving you confidence in what you’re taking—every single time.

While we don’t publicly share lab reports due to commercially sensitive information, we’re happy to make them available upon request.

We’ll continue with independent testing and routine process reviews to ensure our products meet the highest standards. Thank you for trusting us to fuel your health and performance—safely and effectively.

The Receipts Behind Every Batch

We stand behind our testing — every batch is verified for creatine content and label accuracy by an independent, accredited lab, including stability testing to confirm creatine potency over 12 months and beyond. Results are available on request; please contact us here and we'll share them with you

Does it actually contain what the label says?

Every batch is tested for creatine content and label accuracy before release. What's on the pouch is what's in the gummy — verified, not assumed.

Does it still work by the time you finish the bag?

Every CLNFuel gummy is assigned a 24-month shelf life — and we don't just take that on faith. We put it through accelerated stability testing under stressed heat and humidity conditions, and the gummies held their shape, safety, and full creatine content throughout. We're also running an ongoing real-time stability study, now past the 14-month mark, with every result still checking out.

Making a creatine gummy that stays stable this long isn't simple — it's one of the more difficult, time-intensive products to manufacture well. That difficulty is exactly why we test as thoroughly as we do!
