We are proud to have some of the highest standards of quality in the CBD industry. Every batch of CBD or Full spectrum that our lab receives comes with an independent 3rd party lab test to verify quality and purity standards. Here at Color Up, we take it one step further by periodically getting a 4th party verification. We send samples of the batch to be tested ourselves (4th party) to verify against the 3rd party tests. Being able to guarantee a highly concentrated, pure, pesticide-free product is at the foundation of our company. We are not aware of any other companies that do 4th party testing. Also, check out some of our finished product lab tests. Although we’re not required to test finished goods, we want you to feel confident that our formulations and manufacturing processes deliver the concentration as labeled on the packaging.
