How do you spot genuine Jung Kwan Jang GL Pro Core? 6 checks before you buy in Singapore (barcode check)

Short answer: The fastest way to spot genuine Jung Kwan Jang GL Pro Core is to check the barcode on the back of every box: 8800255101253. The genuine product is made in Daejeon, Korea by Korea Ginseng Corp. and comes in a sealed box of 21 bottles, 25 ml each. Before you buy, choose a distributor who can show proof of authorisation. When it arrives, check the seal, expiry date, name and ingredient list. If the price is unreasonably low, it may be old stock, repacked, or not GL Pro Core at all.

Heads-up: Wellous has issued a notice asking customers not to buy on Shopee, Lazada, Carousell or other third-party platforms. Many listings there are fake, plenty of people only find out after buying, and some sellers pretend to be us.

What are the 6 checks before you buy?

1. Check the barcode first

When your order arrives, look at the barcode on the back of the box first. It should read 8800255101253. If it doesn't match, or it's covered by a sticker, don't open it. Contact the seller straight away.

2. Can the seller show proof of authorisation?

Ask directly. An authorised distributor can show it and won't mind. The same goes for us: you're welcome to ask.

3. Is the price unreasonably low?

Far cheaper than usual, sold as "clearance" or "last few boxes"? Ask where the stock came from and when it expires. If they can't say clearly, don't take the risk.

4. Is the box sealed?

Check whether the seal has been opened or stuck back down, whether any bottle is leaking, and whether any cap has been opened. Record a video when you unbox it; it makes any problem easier to sort out.

5. Is the expiry date clear?

The expiry date should be printed clearly, not scratched off or covered by a sticker. If it's close to expiry, ask before you order.

6. Check the name and ingredient list

The name is GL Pro Core, the brand is Jung Kwan Jang, and it's made in Korea. The ingredient list should show red ginseng extract at 8.70%, and the nutrition label 0 g sugars a bottle. If anything doesn't match, don't drink it.

Why not buy from Shopee, Lazada or Carousell?

Most listings on Shopee, Lazada or Carousell are third-party resellers outside the authorised channel. The usual problems: you can't tell where the stock came from, you don't know how it was stored (Singaporen heat in a warehouse or a car affects the product), nobody is responsible if something goes wrong, and there's no money-back guarantee.

Something you drink every day should come in a box you can verify. Buy from an authorised distributor and you get a sealed box, an advisor who follows up, and the 30-day money-back guarantee.

What should you do once it arrives?

• Check the seal and barcode before you open it.
• Store it somewhere cool and dry, out of direct sun. Don't leave it in the car. No fridge needed.
• A little sediment at the bottom of the bottle is normal. Shake before you drink.
• Read the ingredient list before you start. If you're allergic to any ingredient, don't drink it.
