Retatrutide
Finnrick tested 55 samples of Retatrutide (GLP-1, GIP, and GCGR agonist) from Wuhan Wansheng Biotechnology between 4 Aug 2025 and 3 Mar 2026. Fraud: Based on community reports, we have identified wuhanwanshengbio.com as a fraudulent web site aggressively operating in the name of this vendor. It is most likely entirely unaffiliated with the original company, the fraud is putting the public at risk, so we are temporarily putting all tests under review.
