This figure is the measured result for the specific lot named above, from the certificate linked on this page. It is a measurement, not a specification, not a guarantee, and not a statement about any other lot. Elitist Peptides publishes measured per-lot values and does not advertise a catalogue-wide purity figure.

About this certificate. Certificates of analysis are lot-specific. A certificate reports only the tests actually performed on the lot identified on it, by the laboratory named on it, on the date shown — typically identity and purity by HPLC/MS and net fill mass. It is not a statement of sterility, endotoxin content, or fitness for any purpose, and a result for one lot does not describe any other lot. Tests not listed on a certificate were not performed.
What this lot was analysed for
A laboratory runs what it is asked to run. The request line as printed on the report is reproduced below, along with every separate report issued against this lot and the tests nobody asked for.

Verification key
Not yet transcribed
The certificate for this lot carries a verification key, printed below the signature line. The image supplied to us is cropped above that line, so we do not hold the key and we will not print a plausible-looking one in its place. Transcription from the original document is outstanding, and this field will fill in when it is done.
The certificate document
The original report for this lot has not been published as a downloadable file yet. Every figure on this page is transcribed from that report, field by field, and a field that was blank on the paper is blank here.
Until the file is published, the laboratory’s own verification page is the independent check, and that check does not depend on us hosting anything.
Checking this without us
- Read the lot code from the carton or the vial label and open its page here. Every lot has a permanent, public address; none of it sits behind a login.
- Open the laboratory’s own verification page from the link on that lot page and enter the verification key printed on the certificate. The laboratory returns the record it holds.
- Compare the laboratory’s figures against the ones on this site, line for line. If anything differs, the laboratory’s record is the authority, not ours.
Verification keys are transcribed from the certificate images supplied to us, and most of those images were cropped below the key line. Where a key has not been transcribed the lot page says so rather than showing a blank field. Transcription of the remaining keys is outstanding.
