Statement on False Report Regarding MCE Products

Recently, MedChemExpress LLC customers receive false information about our products through E-mails and leaflets. With respect to the malicious defamation, MCE states the following:

1. The GC376 information in the news proves to be unauthentic. Selleck Chemicals deliberately spreads false information and tries to defame MedChemExpress (MCE) products by using unreliable HPLC results. A joint investigation by MedChemExpress (MCE) China and the China Ministry of Agriculture confirms that the sale of counterfeit drugs alleged by Selleck does not exist. The China Ministry of Industry and Information Technology also confirms that the fake news disseminated by Selleck is created by an illegal extortionary website. The purity information of GC376 is forged. The alleged "informed sources" in the E-mail is probably from the competitor company. Selleck's global dissemination of false information is a serious violation of the law. MedChemExpress (MCE) reserves the right to pursue legal action.

2. All products sold by MedChemExpress (MCE) are chemical reagents that are only used for scientific research purpose, rather than clinical human and animal treatment. We never offer any products and services for individual use. MedChemExpress (MCE) strictly abides by this principle and fulfills the responsibility to the whole society. Every day, MedChemExpress (MCE) rejects dozens of product purchase requests for human or animal treatment and maintain a record of them.

3. MedChemExpress (MCE) offers the highest grade products which are assured by performing various analytical tests, such as NMR, LC-MS and HPLC. Our professional team make analysis and quality control according to publications to ensure the accuracy and credibility of our test results. Every report is available on MedChemExpress (MCE) website. As a professional manufacturer of inhibitors, an advanced and reliable quality system has always been guaranteed. During the last year, we have performed over 12,000 NMR, 31,000 HPLC, and 52,000 mass spectrometric analysis. We have earned trust from world-wide scientists due to our strict quality control policy, and established a long-term cooperation with major pharmaceutical companies and well-known scientific research institutions. The research results are recognized by the world's top academic journals and pharmaceutical patents.

4. The article author (Nature Medicine, 2017, 23(4):405-408) clearly states that their detection methods have limitations and may not reflect the exact product purity. Shortly after the article was published (October 22, 2017), we communicated with the corresponding author, discussed the possible shortcomings and errors about the testing methods, and offered them better analysis methods of our products. They are re-testing some of our products and updating data on their website. However, Selleck has fabricated the data and charts to mislead the customers for commercial benefits.

We hope customers deal with rumors rationally and have confidence in MedChemExpress!
