Recent independent testing found concerning issues across the vendor landscape: Endotoxin contamination: FDA investigations found 78% of research-grade retatrutide samples failed endotoxin screening, with levels exceeding 100 EU/mg compared to the pharmaceutical safe limit of 0.1 EU/mg Purity variation: Independent testing of samples from 134 vendors showed purity ranging from 62% to 100% a vendor claiming "99% purity" without independent verification is making an unverifiable claim Quantity accuracy: Vials can contain up to 46% more or less peptide than advertised, making consistent research protocols impossible without verified dosing This is exactly why Finnrick-verified vendors matter
