Order Cancellation

Orders may be cancelled without penalty if cancellation is requested before fulfillment begins.

Once a shipping label has been generated, cancellation is no longer possible and the order must be handled as a return claim if eligible.

  4. Shipping costs are refunded only in cases where the error was ours (wrong item, COA failure, non-arrival)

Do not ship any product back to us without prior written authorization. Unauthorized returns cannot be processed and will be refused.

COA Disputes

If your independent testing contradicts our COA data, we take that seriously. Please send us your test results, the testing laboratory's name and accreditation, and the batch number from your COA. We will review the discrepancy, retest from retained batch samples if available, and work toward a fair resolution. Our goal is scientific accuracy. if our data is wrong, we want to know.
