Tested for Sport

Certify your products to be free of WADA banned substances, and earn the trust of athletes worldwide with the Labdoor Tested for Sport seal.

How it works:

We’ll test your products in FDA-registered labs for 200+ substances listed as banned from sport in WADA’s (World Anti-Doping Agency) annual Prohibited Lists. With continued testing of your products’ lots, you’ll receive access to Labdoor’s Tested for Sport seal to use on product packaging, in online marketing, and in stores with your partner retailers.

Certified Product Labels

Prove to your customers they can trust your brand with labels designed and certified by LTS based on independent laboratory testing.

How it works:

Your adherence to federal regulations for label accuracy and health and safety claims can mean the difference between an evergreen product or one that’s pulled from the market. Instead of combing through convoluted labelling rules yourself, take advantage of LTS’s expertise. We’ll independently test your products and create certified, consumer-friendly labels for you.
