How to spot a counterfeit supplement listing

The biggest risk with a marketplace supplement listing is not the price — it is that a third-party order usually falls outside the manufacturer's guarantee. If something is wrong, the refund route you were counting on does not apply to you.

Why this category attracts counterfeits

Supplements are small, light, long-dated and expensive per gram, and the packaging is straightforward to imitate. You cannot identify a counterfeit from a photograph, and by the time the bottle is in your hand your money has gone to a seller you cannot identify.

Seven signals worth checking

1. A price far below the official range. Nobody sells at a loss for long. Deep discounts usually mean expired stock, a grey-market import or a fake.
2. Photographs that do not match current packaging. Wrong capsule count, outdated label, a different seal.
3. No identifiable seller. If you cannot tell who took your money, you cannot tell who owes you a refund.
4. Vague refund terms. "Contact us for returns" with no window, no address and no process is not a policy.
5. Reviews that do not describe the product. Bulk-bought reviews are generic and oddly enthusiastic about shipping speed.
6. Expiry dates missing or close. A six-month package needs at least a year of shelf life to be worth buying.
7. Pressure mechanics. Countdown timers and invented stock counters exist to stop you checking the six points above.

The guarantee problem

Manufacturer guarantees generally apply to orders placed with the manufacturer or an authorised seller. Buy from a reseller and you are relying on the marketplace's own returns process, which is a different thing with a different and usually much shorter window.

For a product meant to be judged over six weeks, that gap matters enormously. A 30-day marketplace return window closes before you have finished assessing it.

What to do when the box arrives

1. Check the safety seal is intact. If it is damaged or missing, do not use it.
2. Compare the label against the official product photographs.
3. Check the expiry date against how long the package will last you.
4. Photograph the label, panel and other-ingredients line included.
5. Calendar the refund deadline before you take the first serving.

If something looks wrong

Do not take it. Contact the seller in writing, with photographs, immediately. Shipping and product-condition claim windows are usually far shorter than refund windows, so a week of hesitation can close the option.
