Four sourced facts to check before you trust a peptide listing today.
Quality
Check the lot: does your COA match your vial?
Match the lot or batch number on your vial to the one on its certificate. When they match, the purity result describes the vial in your hand. Ask your supplier for the batch COA if the number is missing.
Did FDA just ban peptides? The record says not yet
FDA's interim peptide-compounding notice (RIN 0910-ZD94) is still under White House review and its text is unpublished. Anyone claiming FDA just banned peptides is ahead of the public record.
A seller that labels products 'research use only' and then publishes human-use instructions is contradicting its own label. Treat every other claim it makes, including its COAs, with the same caution.
