Verify Your FlexGuard Batch: Lot FLE-26/GO-6202

This batch is lot FLE-26/GO-6202, certificate reference FLE-6202-26-GO.

Both are filing references rather than laboratory proof, and the difference is the whole subject of this page. A lot code tells you which production run a bottle came from. It does not tell you what was measured in it, and no code on any bottle ever has.

Five checks you can run on a bottle in about a minute, and a straight answer about what each of them actually proves.

On arrival

The five FlexGuard checks, in order

The safety seal

Keep out of reach of children. Do not use if safety seal is damaged or missing. This is the only check that can tell you the bottle has not been opened, and it is the first one for that reason.

The lot code on the base

FLE-26/GO-6202 for this batch. The lot and the best-before date are printed on the base of the bottle where the bottle shows them. A code that does not match the one published here is worth a call rather than a worry: batches change.

The panel against this website

Eight rows, glucosamine sulfate 500 mg first, contains shellfish (crayfish). Compare it with the panel printed here. If they differ, the carton wins and this desk needs to know.

The distributor block

North Scale, Ogden, Utah. A product with a named distributor and a postal address has an owner you can identify, which a surprising number on this shelf do not.

The count

30 capsules. Count them if you like; it takes a minute and it is the only check on this list that measures anything.

Document check

What the FlexGuard lot code proves, and what it does not

Question	Does the lot code answer it?
Which production run made this bottle?	Yes. That is what it is for.
When was it made, and when does it expire?	Yes, via the best-before date printed with it.
Was this batch tested?	No. A code is an index, not a result.
What did the test find?	No. That is what a certificate of analysis is for, and a reference number is not the certificate.
Is the bottle genuine?	Partly. A matching code plus an intact seal from the official channel is good evidence. A code alone is printable by anybody.

Two yes, two no, one partly. Anyone telling you a lot code proves purity is describing a document they have not read.

A reference is not a report

FLE-6202-26-GO is a certificate reference. It identifies a filing. A certificate of analysis itself is a document with assay results in it, usually for identity, heavy metals, microbiology and sometimes potency. Third-party verification programmes exist precisely because a manufacturer's own filing reference is not the same thing as an independent measurement, and this product carries no third-party verification mark.

Ask the desk

Ask this desk about a FlexGuard batch

For anything attached to an order, the order desk on +1 (877) 257-0710 is faster and it is the only party that can see the order record. The website address handles questions about the pages and about what is printed on them.

When to call

What would make a FlexGuard bottle worth querying

A broken or missing safety seal.
A lot code that is illegible, missing, or printed on a sticker rather than the bottle.
A panel that differs from the eight rows published here.
A capsule count that is not thirty.
A best-before date that has passed, or that is missing.
A bottle bought through a channel other than this one, in which case this desk cannot help and the seller you bought from can.

None of those is common and the list exists so that a buyer who meets one knows it is worth a phone call rather than a shrug. The FDA's labelling guide sets out what a compliant supplement label has to carry, which is the standard the carton is being held to here.

What a certificate is

What a FlexGuard certificate of analysis would actually contain

A certificate reference is printed on this site and the certificate itself is not published. Rather than leave that as a shrug, here is what such a document is, so the difference is concrete.

Test	What it establishes	What it cannot establish
Identity	That the material is the species or compound claimed	How much of it is in a capsule
Potency or assay	How much of a marker compound the raw material carries	What the finished capsule contains, unless the capsule was assayed
Heavy metals	Lead, arsenic, cadmium and mercury below set limits	Anything about efficacy
Microbiology	Total counts and the absence of named organisms	Anything about the amounts on the panel
Residual solvents	That extraction solvents are below limits	Whether the extract was standardised

Five tests, and only the second of them speaks to an amount. A certificate is a quality document rather than a dose document.

Two things follow. A certificate would not settle the question this site spends most of its pages on, which is whether 500 mg of glucosamine once a day does what 1,500 mg three times a day was tested to do. And a reference number is not a certificate: it identifies a filing, and this desk can ask the distributor for the document behind it if you write in.

Every page, every journal post, the bottle facts and the ingredients go through review by Dr. Elizabeth Ortiz, MD before they ship. We write these pages from the FlexGuard carton artwork and the distributor’s own batch paperwork. The carton prints a milligram for all eight actives, so beside each one we print the amount the published trials used, including the four rows where the two are an order of magnitude apart. Corrections go onto the page itself and move the review date forward. Write to [email protected]. Last reviewed September 2026 by Dr. Elizabeth Ortiz, MD.
