Executive Summary

  • The distributing company “Serumlab S&C International Limited” is selling hundreds of fake dietary supplements (products with 0% of the advertised ingredients) under dozens of brands on Amazon. Many of these products are top-sellers in their category, and are being purchased and ingested by tens of thousands of customers every month.
  • Third-party testing documentation confirms the significant adulteration of the products they sell, and documented black-hat tactics (such as fake buyer accounts) illustrate how they are able to dominate in the Amazon marketplace and attack legitimate competing sellers.
  • Using a variety of different names, LLC’s, brands, accounts, and storefronts, Serumlab S&C International is growing at an alarming rate, and as a result, so is the proliferation of its adulterated dietary supplement products. Evidence has been compiled to support these assertions in an effort to alert consumers and urge regulatory agencies to take action.

Evidence of Adulterated Supplements

  • The three top-selling products distributed by Serumlab International, (NMN & Resveratrol under the brand “Kompracha,” Liposomal Glutathione under the brand “Star Honor,” and NMN under the brand “NMN Plus,” are all top sellers in the NMN and Glutathione categories respectively. As seen on the product packaging (photos can be found on the “references” page at the end of this report), all three are confirmed to be distributed by Serumlab S&C International LLC. The address as listed is as follows:

(US) Distributed by Serumlab S&C International LLC,

5305 River RD N STE B, KEIZER, OR 97303 USA

These three products are all top sellers on Amazon, with thousands of units being purchased and ingested by Amazon customers every month.

These three products were each sent to two independent ISO-certified labs, and have been confirmed to have 0% of the active ingredients.

In addition to these top three best-selling products, there are hundreds more being sold by SerumLab. An additional 15 Serumlab products were sent for testing (from a number of their different brands), and have been found to be 100% fake.

Conclusion

The strategy being employed by SerumLab International is clear, and effective:

  • Sell adulterated supplements under dozens of different brands.
  • Out-price the competition (by using fake ingredients) to gain market share
  • Flood their own listings with fake positive reviews, and relentlessly attack competitors with negative reviews, using buyer accounts they own

This strategy is enabling them to grow and proliferate with alarming success across many different markets.

Amazon must take action to remove this bad actor in order to ensure a safe environment for its customers, as well as a fair marketplace for its sellers.
