Verification
The three traceability numbers behind your bottle
Three pieces of traceability sit behind this product, which is better than a good deal of the shelf manages. Two are stamped on the bottle, a lot number and a printed best-before date; the third, the certificate of analysis number, was quoted with the batch rather than printed on every bottle. The stock behind this site is lot GLY-26/GO-8205, certificate GLY-8205-26-GO, best before 07-2028.
They do different jobs. The lot number identifies which production run your bottle came out of, which is what matters if a batch is ever withdrawn. The certificate number points at a third-party test of that run. The best-before date is the manufacturer’s own limit on how long it will stand behind what is inside, assuming the storage the label asks for.
None of the three tells you how the 1000 mg is divided between the nine ingredients, because nothing on this label does. Traceability and disclosure are separate things, and this bottle is good at the first and poor at the second. The panel, transcribed.
| Marking | On this stock | Where to find it | What it is for |
|---|---|---|---|
| Lot number | GLY-26/GO-8205 | Stamped on the bottle, usually on the base or the lower side panel | Identifies the production run. It is the number the order desk needs if anything about the bottle is wrong, and the number a recall would be issued against. |
| Certificate of analysis number | GLY-8205-26-GO | Quoted with the batch, not printed on every bottle | A reference to a third-party test of the batch. The number is a pointer to a document; the document itself is not published. |
| Best before | 07-2028 | Stamped alongside the lot code | The date the manufacturer will stand behind the product to, assuming it has been stored as the label asks. A printed expiry is commoner on this label than on most of the shelf. |
| Safety seal | Intact and unbroken | Under the cap | The label says: do not use it if the safety seal is damaged or missing. That is a condition rather than advice. |
| Brand mark | VITALIFES | On the label face | The name the label carries. The distributing company’s street address is not published on the bottle. |
The check
Six steps, and the first one is the important one
All of this happens before the seal is broken, because an unopened bottle is a return and an opened one is an argument.
Do it before you break the seal
An unopened bottle can go back. An opened one is a different and much longer conversation. The whole check takes under a minute, so do it while the parcel is still open on the table.
Turn the bottle over and read the stamp
You are looking for two things printed together: a lot code and a date. On this stock they read GLY-26/GO-8205 and 07-2028. The stamp is inked directly onto the plastic rather than printed on the label, so it can be faint on a dark surface.
Check the date is in the future, with room
A best-before of 07-2028 is a long way out. A bottle with a date close to today, or already past it, is a bottle to call about rather than to take.
Check the seal under the cap
Unscrew the cap without breaking anything and look at the seal across the neck. It should be flat, unbroken and stuck down on all sides. If it is torn, lifted or missing, stop.
Compare the panel with the one we publish
The Supplement Facts on your bottle should read the same as the panel transcribed on this site: a 2 capsules serving, 30 servings a container, and one blend line printed Test Boost Proprietary Blend 1000 mg with nine ingredients named underneath and no individual amounts.
Call the desk if anything differs
+1 (302) 200-3480 with your order ID. A different lot is not automatically wrong, because manufacturers run more than one batch and stock rotates. It is simply the moment to ask.
If yours differs
Four differences, and what each one means
A mismatch is a question, not a verdict. Three of the four cases below are ordinary and one of them is not, and knowing which is which saves an unnecessary phone call or an unwise capsule.
A different lot number
Common and usually harmless. Batches change. Call the desk, quote both the number on your bottle and the order ID, and ask whether the batch is current. Do not open it while you are waiting.
A different or missing best-before
Worth a call before anything else. The date is the manufacturer’s own limit and a bottle without one cannot be checked against anything.
A damaged or missing safety seal
The label settles this one: do not use it. Leave the bottle closed, photograph it, and call the order desk. This applies whatever the outer box looked like.
A panel that does not match ours
If the Supplement Facts on your bottle differ from the panel we publish, we want to know as much as you do. Send a photograph to [email protected] and we will either correct this site or tell you what we think you are holding.
The limit
We have a certificate number. We do not have a certificate
This is the part of the page that matters most, so it is not going at the bottom in small type. A certificate of analysis is a laboratory document. It names the batch, states what was tested for, gives the results, and carries the name of the laboratory that produced it. Typically that means identity of the botanical material, heavy metals, microbial contamination and sometimes a marker compound.
What we were given is GLY-8205-26-GO. That is a reference number, and a reference number on its own is not a test result. It does not tell you what was tested for, what the limits were, what the readings came back as, or which laboratory did the work. Quoting it at you as though it were evidence would be the easiest paragraph on this site to write and the least honest.
So the position is: the certificate of analysis document is not published. If the seller supplies it we will publish it here and say what it covers. Until then, this page tells you what the number is for and stops. The order desk on +1 (302) 200-3480 is the place to ask, and if you get a copy we would genuinely like to see it.
What a number can and cannot prove
A lot number is genuinely useful: it ties your bottle to a run. A certificate number without the certificate is a pointer to a document nobody outside the company has read. The lot is printed on the bottle; the certificate number was quoted with the batch, and only the lot can be checked. The FDA questions and answers on dietary supplements explains what the regulator does and does not do before a supplement reaches a shelf.
