Made in an FDA-registered, cGMP facility
LeanBurn Drops is manufactured in the United States in a facility that is registered with the U.S. Food and Drug Administration and operates under Current Good Manufacturing Practices (cGMP). In plain terms, that means documented procedures, trained staff, controlled environments, and records that trace each finished bottle back through its production run. cGMP is the baseline a serious supplement should meet, and it is non-negotiable for us.
Independent, per-batch lab testing
Manufacturing standards are only half the story. Every production batch of LeanBurn Drops is also tested by Crestline Bioassay Laboratories, LLC, an independent laboratory accredited to ISO/IEC 17025, the international standard for testing competence. Using an outside lab matters: it means the numbers on your Certificate of Analysis are not marked by the same people who made the product.
What each batch is tested for
| Test | Method | Purpose |
|---|---|---|
| Identity | HPLC-UV | Confirms each botanical is what the label says |
| Potency / active purity | HPLC-UV | Verifies actives meet target levels (99.2% this cycle) |
| Heavy metals | ICP-MS | Screens lead, arsenic, cadmium and mercury (< 0.5 ppm) |
| Microbial safety | USP method | Confirms results within USP <2021> limits |
| Pesticide screen | GC-MS / LC-MS | Checks for agricultural residues on botanicals |
A batch only ships once it clears all of the above. The current results are summarized on the verification page under Certificate of Analysis CRB-26-4471.

Quality and verification, together. Think of it this way: this quality page is the process, and the verification page is the receipt. One explains how we test; the other shows the result for the exact batch in your hands.
