Laboratory Tested


C4 Laboratories is a cannabis testing lab that empowers patients and businesses with information that’s honest, accurate, and easy to understand so they can make informed decisions.

Manufacturers, producers, growers, and dispensaries across Arizona count on us for credible test results that show them and their patients the true potency and safety of their medications.

While having honest, consistent data is crucial, that data is only helpful if you know what it means. That’s where C4 comes in. By taking an educational approach and translating complex data into understandable information, we help cannabis businesses prove their claims, drive sales, and feel confident they’re delivering safe, high-quality medications that will truly help their patients.


You have plenty of options for cannabis testing, but C4 wants to be your partner of choice. We’re the only team in Arizona that you can rely on for honest testing, accurate and consistent results, and educational, personable service.

It’s all too common to see testing labs alter their results or strategically pick and choose the data they share. Patients are our priority, so we believe honesty is the best policy. We tell you the truth, not just what you want to hear. This commitment to transparency ensures you get the credible information you deserve while raising the bar for the industry as a whole.
