Certificates of Analysis (COA)
At Zello Labs, every batch undergoes internal quality control testing throughout the manufacturing process. Raw materials are evaluated prior to production, and finished products are tested to verify identity, purity, and sterility standards.
Due to proprietary and legal considerations, Certificates of Analysis are not publicly distributed. However, we strongly support independent verification and encourage customers to conduct third-party testing at any time.
For independent testing, we recommend reputable analytical laboratories such as Janoshik Analytical and Freedom Research Testing.
As part of our commitment to quality and transparency, Zello Labs will provide 100% reimbursement of the testing cost in the form of store credit upon submission of valid proof of testing.
If you have questions regarding product quality, batch verification, or testing procedures, please contact our support team.
