Slim Metrix Batch Verify: Lot Number, CoA Reference and Bottle Checks
The Slim Metrix lot reference is SLI-26/GO-6640 and the CoA reference is SLI-6640-26-GO. Both are reference numbers, not lab proof, because no certificate has been published. To check a bottle, confirm the seal, match the Supplement Facts panel, find the lot on the base and look for the maker's name on the label.
What do the Slim Metrix lot and CoA numbers mean?
Two reference numbers. Here is what each one can and cannot tell you.
- Lot reference
SLI-26/GO-6640- CoA reference
SLI-6640-26-GO- Where a lot appears
- On the base of the bottle, when the bottle shows it
- What they do
- Name a production batch and the paperwork that goes with it
- What they do not do
- Prove purity, strength or safety
The lot number links a bottle to one production run. If a question ever comes up about a batch, the lot is how it gets traced. The CoA reference, SLI-6640-26-GO, points to a Certificate of Analysis for that run.
Both numbers reached us as references only. We have not seen the certificate, so we report no results from it.
Lot numbers exist so a batch can be traced from the factory to the shelf. If a batch ever needed checking or recalling, the lot is how the right bottles would be found. That is why it is worth noting yours.
Why is a Slim Metrix CoA reference not lab proof?
A reference points to a report. Only the report shows results.
A Certificate of Analysis is a lab report for one batch. A complete one lists the tests, the results, the lab's name and a date. Those details are what let a buyer check a claim.
A reference number is just the label on that report. It shows a document may exist, but not what it says. So SLI-6640-26-GO helps with tracing, not with proving.
A reference number compared with a full Certificate of Analysis
| Feature | Reference number | Published CoA |
|---|---|---|
| Names the batch | Yes | Yes |
| Shows test results | No | Yes |
| Names the lab | No | Yes |
| Shows measured amounts vs the label | No | Yes |
| Available for Slim Metrix today | Yes | Not published |
If a certificate is released, look for the lab's name, the test date and a measured amount beside each label amount. Our testing and quality page covers what a buyer can confirm today.
Until then, the checks you can run yourself matter more than any number. A sealed bottle, a matching label and a readable lot tell you the product left the factory as a finished, packed item.
How to check a genuine Slim Metrix bottle
Seven checks. Most take a few seconds per bottle.
Check the container
Genuine Slim Metrix comes in a labeled bottle of 30 capsules with a white cap and a purple label. A pouch, bag or plain jar is not the product sold here.
Check the seal
Each bottle should arrive sealed. Do not take capsules from a bottle whose seal is broken or missing.
Match the Supplement Facts
The panel should read: 1 capsule per serving, 30 servings, zinc 5.5 mg, chromium 0.05 mg and a 276 mg proprietary blend.
Read the directions
The label should say adults take one capsule daily, preferably in the morning, with or without food.
Find the lot number
Look on the base. The lot and best-before are printed there when the bottle shows them. Note the lot and compare it with SLI-26/GO-6640.
Find the maker's name
Read the label for the name and address of the manufacturer or distributor. Note it down, as the supplied images do not show it.
Confirm the seller
Find your order email from goslimmetrix.com. If you bought elsewhere, the checks above carry even more weight.
What should the Slim Metrix label panel show?
Line up your bottle with the panel. Small differences are worth a phone call.
Supplement Facts lines per capsule
| Line | Amount | % DV |
|---|---|---|
| Total Calories | 0 | – |
| Total Carbohydrate | <1 g | <1%* |
| Zinc (as Zinc Gluconate) | 5.5 mg | 50% |
| Chromium (as Chromium Picolinate) | 0.05 mg | 41.67% |
| Proprietary Blend | 276 mg | ** |
Under the blend, the label lists eight ingredients: alpha lipoic acid, green tea extract, milk thistle, berberine HCl, resveratrol, cayenne, Korean ginseng and banaba.
Other ingredients should read: Hypromellose (Vegetable Capsule), Microcrystalline Cellulose, Magnesium Stearate, Silicon Dioxide. The label prints 41.67% DV for chromium. That matches an older reference value, so it is not an error on your bottle. The Supplement Facts page explains every line.
What should genuine Slim Metrix capsules look like?
The capsule itself is one more check, and it takes a glance.
The product images show purple capsules, and the label lists hypromellose as the capsule shell. That is a plant-based vegetable capsule, not gelatin.
Each bottle should hold 30 capsules of the same size and color. The filling is a powder, so a light rattle is normal.
Signs to stop and call
- Capsules of mixed colors or sizes
- Tablets, gummies or liquid instead of capsules
- Capsules that are cracked, damp or stuck together
- A strong or odd smell when you open a new bottle
- Fewer than 30 capsules in a sealed bottle
Who makes Slim Metrix, and where is that on the bottle?
This detail is not on our images, so your bottle is the best source.
The name of the manufacturer or distributor is not visible on the label images supplied to us. So we cannot print it here. Check the label on your own Slim Metrix bottle, often near the directions or the barcode.
U.S. supplement labels normally carry the name and place of business of the maker, packer or distributor. Finding that line on your bottle is one more sign it is a finished retail product.
- Look near the directions, warnings and barcode
- Note the company name and city
- Keep that note with your lot number photo
- If no such line appears, call +1 (562) 523-2626 and ask
Goslimmetrix is a USA Authorized Slim Metrix Retailer. It sells the product. It does not make it.
What should you do if a Slim Metrix bottle fails a check?
Four steps protect both your health and your refund.
- Stop. Do not take any capsules from that bottle.
- Photograph the label, the seal, the base and the parcel.
- Call +1 (562) 523-2626 with your order ID and describe what you found.
- Keep the bottle and packaging until the desk tells you what to do.
A failed check on an order from this site is handled by the order desk. It sits alongside the 60-day guarantee. If you bought elsewhere, report it to that seller instead.
Evidence makes the call quick. Photos taken in good light, with the lot number readable, answer most questions before they are asked. Keep the outer box too, since its label links the parcel to your order.
Should you check every bottle in a Slim Metrix pack?
A few seconds per bottle is all it takes.
Time to check a whole pack
| Pack | Bottles to check | About how long |
|---|---|---|
| 2 bottles | 2 | Under a minute |
| 3 bottles | 3 | About a minute |
| 6 bottles | 6 | Two to three minutes |
Yes. Check each seal and label, and note each lot number. Bottles in one pack often share a lot, but they do not have to.
Open one bottle at a time. The sealed bottles stay protected until you need them, and you can recheck each one before first use.
A simple bottle log
Keep a short note on your phone with one line per bottle: the bottle number, the lot, the best-before date if shown, and the day you opened it. For example: “Bottle 1, lot SLI-26/GO-6640, opened September 24, 2026.”
The log also tells you when to reorder. At one capsule a day, each bottle you open marks another 30 days.
Slim Metrix batch and bottle questions
What is the Slim Metrix lot number?
The lot reference supplied to us is SLI-26/GO-6640. A lot number names one production batch. It helps trace a bottle, but it does not prove what is inside.
Is the Slim Metrix CoA number a lab result?
No. SLI-6640-26-GO is a reference number for a Certificate of Analysis. The certificate itself has not been published, so no results or lab name can be shown.
Where is the lot number on a Slim Metrix bottle?
Look on the base. The lot and best-before are printed there when the bottle shows them. The print can be small, so use a bright light or a phone photo.
My Slim Metrix bottle shows a different lot. Is it fake?
Not by itself. Each production run gets its own lot number. If the label, seal and capsule count all match, a different lot is not a warning sign.
Who makes Slim Metrix?
The manufacturer or distributor name is not visible on the images supplied to us. Check the label on your own bottle for it. Goslimmetrix is an authorized retailer, not the maker.
Has Slim Metrix been tested by an independent lab?
No independent lab certificate has been published. The brand's graphic says “3rd-party tested,” but no report backs that line yet. If one is released, we will link it here.
What if my Slim Metrix bottle fails a check?
Do not take the capsules. Photograph the label, seal and base, then call +1 (562) 523-2626 with your order ID.
Do Slim Metrix bottles in one pack share a lot number?
Often, but not always. A pack can hold bottles from more than one production run. Note the lot on each bottle so you know which is which.
