NSF International is an independent non-governmental organization that has worked for more than 75 years to develop health and safety standards for food, water systems, and health products such as dietary supplements. It started back in the 1940s in the University of Michigan’s School of Public Health as the National Sanitation Foundation, but expanded into other industries in more than 150 countries.
NSF International certifies products that have met its standards for quality and manufacturing practices with the NSF mark. There are different types of certifications for different products, such as the Certified for Sport mark for dietary supplements.

cbdMD is the first CBD company whose products qualify for NSF International’s Certified for Sport designation. That means these products have been tested for over 280 known banned athletic substances, including unacceptable levels of THC. No contaminants, no additives, just great CBD benefits.

NO!!! CBD topical products never enter your bloodstream unless they make contact with a mucous membrane (which you should avoid for safety precautions). But even if they do, our Superior Broad Spectrum formula is THC-free,* and most drug tests are designed to detect THC, not other cannabinoids. All CBD products from cbdMD start with a formula derived from hemp plants with less than 0.3% THC by dry weight.

Freeze and other CBD topical products with painkillers are typically used after activity, targeting stiff and sore spots. You can use it preventatively if you like, but be careful not to use it to mask the pain to the point where you injure yourself.
