This COA was tested by an independent third-party lab (Janoshik). However, the report is for an anabolic steroid (Nandrolone Decanoate oil) with a concentration of 186.37 mg/ml, not a peptide. Purity, quantity deviation, and endotoxin information for peptides are not applicable. The test date is February 26, 2026, but recency is unknown. Customers can cross-check on the lab's public verification URL.
