Yes, 4 vendors listing SS-31 publish an independent third-party COA (Janoshik): Wolverine Peptides UK, UK Peptide Supply, Retapeptide, Kensington Labs. Others show an in-house or no published COA, so always check the batch COA before buying.

Trust a COA that is (1) from an independent lab such as Janoshik, not in-house, (2) tied to the exact batch you're buying, and (3) recently dated. An undated or old COA, or one for a different batch, does not prove the quality of current stock.
