- Following community reports, we have identified clear signals of large-scale fraud in the name of Nantong Guangyuan Chemical GYC and are retracting all of their tests. The presence on the site ggpeps.net of an obviously fraudulent copy of the Finnrick web site (PeptideMeter.com) shows intent to deceive. Community reports include products not shipped after payment is taken. Finnrick strongly advises against purchasing from this vendor.
