Lab Reports & Testing

What we ask for before a product ships, what documentation exists, and how to request the paperwork behind the specific bottle in your hand.

01

What we ask for before a product ships

Before anything goes live we request the same three things from the manufacturer: ingredient documentation, the facility's certifications, and the lab work for that product. Formulated to halal standards — alcohol-free, gelatin-free, no pork derivatives.

Where documentation for a claim does not exist yet, the claim does not go on the page. Claims lag evidence — per product and per lot, never brand-wide.

02

Manufacturing

ZMZM Labs products are produced by a contract manufacturer in the United States.

03

Lab reports and Certificates of Analysis

Lab reports and Certificates of Analysis are available on request, per product and per lot. Not one flattering document waved at everyone for a year — the paperwork behind the specific lot you received.

Email support@zmzmlabs.com with the batch number printed on your package, or use the Certificate of Analysis request form, and we will send what exists for that lot.

04

Skincare and wudu

Our leave-on skincare is formulated for use around wudu — no silicones, no film-forming polymers, no waterproof acrylates, nothing engineered to sit on top of your skin like cling film.

A published water-permeability test is the next step, and we have not run it yet. We are not publishing a result before it has been properly run — so there is no pass, fail, or score on this page to report.

Questions, batch numbers, or a specific COA request?

Email support@zmzmlabs.com with your order number or batch number.
