Purity & Verification

Every batch tested. Every result published.

Purist Peptides is a South African supplier of research-grade compounds. Each production batch is assayed by an independent laboratory and verified to a minimum of 99% purity before release — and we publish the certificates.

The Purist Standard

Three pillars behind every vial

The integrity of your research depends entirely on the integrity of your materials.

Scientific Fidelity

Every compound is synthesised using industry-leading techniques to ensure consistent purity from batch to batch.

Uncompromising Transparency

We publish structured purity data and the certificates themselves, rather than asking you to take a claim on trust.

Premium Handling

From lyophilisation through to vacuum-sealed glass vials, every unit is prepared to a clinical standard.

Verification

How every batch is verified

Purity is the single variable that invalidates a study fastest, so it is the one we test hardest. Each production batch goes to an independent third-party laboratory for HPLC assay before release, and is only released when it verifies at 99% purity or above.

Synthesis

Controlled synthesis and purification.

Submission

Sample sent to an independent lab.

Questions

Purity and testing FAQ

Who performs the testing?

An independent third-party laboratory — Bioindustrial Services in Boksburg, Gauteng. We do not self-certify purity.

What does 99% purity actually mean?

It is the percentage of the sample confirmed as the target compound by HPLC assay. The certificates above show the exact figure for each batch, not a rounded claim.

Can I get the certificate for the vial I received?

Yes. Every batch is traceable to its assay. Send your batch number and we will return the matching certificate.

How are the vials prepared and stored?

Compounds are lyophilised under controlled conditions and vacuum-sealed in glass vials to protect stability in transit and storage.

Are these products for human use?

No. All Purist Peptides products are supplied strictly for laboratory research use and are not for human or veterinary consumption.
