A bottle of a popular supplement was listed at half the retail price, by a seller with no reviews, no store history, and a profile picture that was a stock photo. The listing had 200 sales. The product inside the bottle could have been the real supplement, a diluted version of it, a different powder entirely, or nothing at all. There was no way to know from the listing, and that is the point. With a supplement, the check has to happen before the purchase, because after the purchase the evidence is in your body.

Counterfeit supplements are a real category, and they are harder to spot than counterfeit bags, because the product is a powder or a capsule in a bottle, and the bottle is easy to copy. The checks are the same skills used for any other product: the seller, the listing, and the product itself. The difference is the order. With a bag, you check the product when it arrives. With a supplement, you check the listing before you buy, because the arrival check is a lab test you will never run.

## The seller first, not the price

Start with the seller, not the product. An authorized seller is listed on the brand's own website, or the listing says sold and shipped by the brand or by a named retailer. A third-party seller with no history, no reviews, and a profile created last month is a filter, not a deal. The price is the second filter: a supplement at half the retail price is either stolen, expired, or fake, and the listing will not tell you which one.

Check the seller's catalogue. A legitimate supplement seller sells supplements, usually from a small set of brands, with consistent pricing and real photos. A counterfeit seller sells a little of everything, with stock photos, vague descriptions, and prices that are always the lowest on the page. The pattern is the tell, and it shows in the catalogue before it shows in any single listing.

## The product checks you can do from the listing

The batch code is the most useful check. A genuine supplement has a batch or lot code printed on the bottle, usually four to twelve characters, and the code on the bottle has to match the code on the box. A listing that shows the bottle but not the code, or shows a code that is blurred, or uses the same photo for every listing, is hiding the one thing that would let you verify it. Ask the seller for a photo of the batch code before you buy, and check it against the brand's verification tool if the brand has one.

The seal matters too. A genuine supplement has a sealed bottle, with a tamper-evident band or a sealed cap, and the seal should be intact in the listing photos. A bottle with a broken seal, a loose cap, or a label that is peeling at the edges is a bottle that has been opened, refilled, or relabeled. The packaging is part of the product, and a counterfeit operation that copies the bottle often gets the seal wrong.

The listing photos are the third check. A genuine seller photographs the actual bottle they are selling, with the label, the batch code, and the seal visible. A counterfeit seller uses the brand's own marketing photos, which show the product at its best and hide everything that would identify the specific bottle. Stock photos only is a filter. Real photos of the real bottle is the standard.

## After it arrives, and if it is wrong

When the bottle arrives, check the batch code against the listing photo, check the seal, and check the label for spelling errors, blurry printing, or a color that is slightly off. A genuine bottle is consistent. A counterfeit bottle is usually close, and close is where the errors show: a misspelled ingredient, a font that is slightly wrong, a label that does not line up. If anything is off, do not take it. Photograph it, report the seller, and ask for a refund through the platform, with the photos attached.

Reporting matters more for supplements than for other products, because the platform's removal process takes one to seven days for a clean report, and the seller will relist in the meantime. A report with photos of the bottle, the batch code, and the listing is a report the platform can act on. A report that says the product looks fake, without photos, is a complaint. The difference is the evidence, and the evidence is the bottle in your hand.

## Frequently asked questions

### How can I tell if a supplement listing is counterfeit before buying?

Start with the seller: an authorized seller is listed on the brand's website, and a third-party seller with no history and a price at half retail is a filter. Then check the listing photos: real photos of the actual bottle, with the batch code and seal visible, is the standard. Stock photos only is a warning.

### What is a batch code and why does it matter?

A batch or lot code is printed on the bottle, usually four to twelve characters, and the code on the bottle has to match the code on the box. It is the one thing that lets you verify the specific bottle. Ask the seller for a photo of the batch code before you buy.

### What should I do if the supplement I received looks fake?

Do not take it. Photograph the bottle, the batch code, the seal, and the label, report the seller with the photos attached, and ask for a refund through the platform. A report with photos is evidence the platform can act on. A report without photos is a complaint.

### How long does it take a platform to remove a counterfeit supplement listing?

A clean report on a clear counterfeit usually gets a decision in one to seven days. The seller will often relist in the meantime, so keep the evidence and file again with the pattern attached.
