Certificate of analysis lookup
Paste the batch number printed on your vial label. The certificate reports HPLC purity, retention time, mass-spec identity, and counter-ion content for that batch only.
Every Renpet Research vial ships with a batch number. The certificate of analysis is generated from the same testing run that produced the vial.
Verifying authenticity
A batch number that resolves here to a matching certificate is the way to confirm a vial is genuinely ours. We sell only through this site — not via third-party marketplaces or resellers — so treat vials with no batch number, or a batch number that doesn’t resolve above, as unverified. If a number doesn’t match, email support@renpet-research.com.
