Who tests Proof products?

SC Labs, an independent, state-licensed and ISO/IEC 17025 accredited cannabis testing lab in California. Every batch must pass before it can be sold.

Is the whole product tested, or just the cannabis?

The whole finished product. In California, every ingredient in the bottle is tested together, not only the cannabis oil that goes into it.

Why testing shapes how we formulate

The face serum that failed

In 2019 we made our first batch of face serum with only sustainably sourced, organically grown ingredients, and it still failed testing. There was no jasmine extract available that could pass California's pesticide standards, even when organically grown, because of soil contamination.

It taught us how rigorous cannabis testing is, and how much goes unchecked in food and cosmetics. Every Proof ingredient has to meet that standard.
