You have plenty of options for cannabis and hemp testing. We want to be your partner of choice. C4 is the only team in Arizona that you can rely on for complete confidence in your test results and an easy, enjoyable process.
C4 has made significant investments to ensure fast turnaround of test results, including purchasing additional lab equipment, planning proactive maintenance schedules to minimize downtime, hiring more staff and reorganizing the team for higher efficiency, moving to a larger lab with more space for testing, and extending lab hours.
Our lab equipment and processes have been fine-tuned to provide reliable results with minimal variation, and your Lab Liaison can walk you through the reports to ensure you understand the data at all times. If results show a problem, we always tell the truth and work with you to correct it.
As a C4 customer, you are assigned a Lab Liaison whose sole job is to serve you and make your job easier.
If you test with C4 often, you can also join the Chronic Customer Program for even more perks, including priority service and discounts.
