Some people are now anonymously calling out the company on Instagram, alleging that they’ve experienced severe health problems after eating F-Factor products — from full-body rashes, to severe gastric distress, and even amenorrhea. Some also claim the products may contain lead and asked F-Factor to release a Certificate of Analysis (COA), which would provide lab results of their products' quality control tests.

LGM Pharma has separate procedures for qualified suppliers and new suppliers. The company requires a certificate of analysis (CoA), all shipping documents, and the material safety data sheets from suppliers that have already been audited and qualified, according to Lenox.“With a new supplier or with any concerns, we advise our clients to do the release testing themselves. It can be very dependent on the product and the nature of the relationship with the vendor—their reputation, reliability, qualification status,” he says. (PharmTech)
