SlimBound testing and quality: what each batch faces

Testing tells you what is in the capsule and what is not. It does not tell you whether the formula works. Those are different questions and this page only answers the first.

The facility

SlimBound is manufactured in the United States in a facility registered with the FDA and operating to current Good Manufacturing Practice. Registration is not approval: the FDA does not approve dietary supplements, and any page telling you otherwise about any brand is wrong. What cGMP governs is process. Identity of incoming material, cleaning between runs, batch records, staff training, retained samples.

The laboratory

Finished-goods testing for the current run was carried out by Superior Assay Partners, accredited to ISO/IEC 17025 for the methods listed below. That accreditation is about the competence of the lab, not an endorsement of the product. Results for batch SB/0417-26 are summarised under certificate SAP-26-1188.

What testing cannot establish

Three things, stated plainly. It cannot establish efficacy: a batch can be clean, correctly identified and still not do much for you. It cannot substitute for a printed label: potency testing on a proprietary blend confirms an active fraction, not a milligram figure per ingredient, which is why our label page still reads "not published". And it cannot vouch for a bottle we did not ship.

Retained samples and shelf life

Samples from each run are retained by the manufacturer for the shelf life of the batch plus one year, which is standard practice and the reason a complaint about a specific lot can still be investigated months later. The expiry date is printed on the base of the bottle beside the lot code.
