In the vendor's own words
Written by the vendor · Not verified by PeptideBase
NextGenPeps is a United States supplier of research-use peptides, stating that its materials are tested for purity, weight, content and endotoxins, and publishing a public certificate of analysis library. It names Janoshik Analytical as its testing laboratory and states same-day dispatch. It is a separate business from the similarly named NextGen Peptides at ngpeptide.com, which is listed here independently. Those are the vendor’s own statements. PeptideBase has not independently verified them and holds no laboratory records for this supplier.
