ASKED.

Your batch number is printed on the bottom of the bottle and on the outer box. It follows the format ZL-XX-YYYY-MMDD. You can also scan the QR code on the label to be taken directly to your batch results.

A COA is an official document from a testing laboratory confirming the identity, purity, and potency of each ingredient in a specific product batch. It verifies that what's on the label is actually in the capsule.

Third-party testing is conducted by an independent, accredited laboratory with no financial interest in the results. This is the gold standard for supplement verification — which is why we publish these results publicly for every single batch.

Yes. GreMin® is a proprietary ingredient developed through controlled, peer-reviewed research using natural sources. It is GRAS-recognized and has been thoroughly safety-tested at the doses used in our formulation. Full documentation is available via the MSDS link above.

Every batch is tested before it ships. Results are published here within 48 hours of lab sign-off — typically 5–7 days post-manufacturing. No product leaves our facility before results are confirmed.
