User Experience:
We received more than ten offers for ergosterol (1 kg) on Alibaba from the Chinese suppliers. The product of Xi’an Zelong Biotech Co., Ltd. was neither the cheapest nor the best in quality, but it was the best among those studied in terms of price-quality ratio. For this reason, it was chosen for further work, and it was decided to purchase a larger portion (8 kg) from this company.

After paying 6060$, FedEx soon delivered a barrel containing 8 kg of white powder. But the inspection showed that the obtained product was not ergosterol. This was very easily established by comparing the NMR spectra of the real ergosterol, which was the object of our contract. It turned out to be more difficult to establish what it is. This was done in the specialized laboratory of the Belarusian State University. Using IR spectroscopy and X-ray diffraction analysis, it was shown that this product is amorphous cellulose. The latter is ideal for use as a fake product. The amorphous cellulose is low in cost and good in appearance.

Xi’an Zelong Biotech was represented by a person named Blake Wu. Attempts have also been made to contact sales manager Jacob Liu, but these have not been successful.

Of course, we have repeatedly made proposals to replace the product: “Why don’t you want to get your product back so you can do the analysis yourself and make sure it’s not ergosterol?”. The answer was something like this: “How do I know if I got my product? Maybe you changed my product. You returned me another product other than ergosterol, so you can ask me for a refund.”

Searching for a company on Google, we found that we are not the first victim of this company. On the Pakistani site we found the following entry: “I ordered a product from “Xian Zelong Biotech Co Ltd” on Alibaba. But the company sent me the fake products and when I asked them to return the payment, they said they will and delayed the return by claiming that their company was on a Chinese holiday or their CEO was traveling. When more than 1 month passed the company refused to return payment and stopped communication.”
