Cannabis Testing that Blends Science and Service

With C4’s analytical testing services, cannabis businesses gain the confidence that their medications are safe, reliable, and consistent, while patients gain the confidence to ask hard questions and hold the companies they buy from to a higher standard.

Test results are delivered through Confident Cannabis, a simple online system for storing, tracking, and searching past reports. Our team also provides a full consultation and analytical review of the results free of charge to help translate your data into easy-to-understand information you can use to make informed decisions. (Pediatric patient consultations are provided free of charge.)

In addition to testing, C4 works with manufacturers on product development and optimization, and collaborates with cultivators on grow analytics. Services include mold culture testing, viral detection with sentinel plants, and comprehensive analysis of environmental conditions.

All microbial analyses report CFU's (colony forming units).

Samples which arrive at our facility after 2PM will be considered received 9AM the following business day for the purposes of determining turn around time. Turn around time may vary depending upon the volume of laboratory samples we currently have. Posted turn around times cannot be guaranteed.

Testing of additional compounds and bulk pricing are also available. Contact us for details.
