Certificates of analysis

Certificates of analysis

The batch number is printed on the vial label, next to the strength.

Short answer

The certificate library lists every published certificate of analysis by compound and batch. Each report names the lab, the method, the test date and the purity and identity results. Search the batch number printed on your vial.

Which batches have published certificates?

Certificates publish here as each lab report arrives. Every batch in the range is listed below with its status.

How is each batch tested?

  • HPLC analysisMeasures purity: the share of the target peptide among detected components.
  • Mass spectrometryConfirms identity: the measured mass matches the expected molecule.
  • Independent laboratoryAn outside lab runs the tests and issues the report. The lab is named on every certificate.
How we test every batch

What is a peptide certificate of analysis?

A certificate of analysis (COA) is a lab report for one batch. It names the lab, the method and the test date, reports purity by HPLC and confirms identity by mass spectrometry. It carries the batch number printed on the vial.

How do you tell if a certificate is real?

Check four things: the batch number matches your vial, the lab is named with a report number, the test date is recent for the batch, and the lab confirms the report number when you ask it. A single PDF for a whole product range proves nothing about your vial.

Which lab tests Peptides Collective batches?

[Lab name, location and accreditation from Nico.] The lab is named on every certificate.

What does a certificate not tell you?

A standard certificate reports identity, purity and sometimes net content. It does not test for sterility or endotoxin unless it says so, and it describes the sample tested on the date shown. Storage after dispatch is outside what any certificate can show.

Certificate questions

What is COA for peptides?

A COA (certificate of analysis) is a lab report for one batch of a peptide. It names the lab, the method and the test date, reports purity by HPLC and confirms identity by mass spectrometry.

How to tell if peptide COA is real?

Check that the batch number matches your vial, the lab is named with a report number and a test date, and the lab confirms that report number when you contact it. A single report reused across a whole range proves nothing about your vial.

Is a peptide a steroid?

No. Peptides are short chains of amino acids joined by peptide bonds. Steroids are lipids built on a four-ring carbon skeleton. The two groups differ in structure and in how they act.

How to tell if a coa is legit?

Match the batch number to your vial, look for a named lab, a report number and a test date, and ask the lab to confirm the report number. Treat an unnamed lab or a missing batch number as a failed check.

What does a certificate show?

The compound and batch number, the lab and its report number, the method (HPLC for purity, mass spectrometry for identity), the purity result, the identity result, net content where tested and the test date.

What does HPLC purity mean?

HPLC (high-performance liquid chromatography) separates a sample into its components. Purity is the share of the detected material that is the target peptide, reported as a percentage of total peak area.

What does mass spectrometry confirm?

Mass spectrometry measures the mass of the molecule. A match to the expected molecular mass confirms the identity of the peptide.

Which lab issues the certificates?

[Lab name and accreditation from Nico.] The lab is named on every certificate.

What purity is typical?

The purity figure is specific to each batch, and the certificate reports the measured value. HPLC purity describes the share of the target peptide among detected components. The amount of peptide in the vial is a separate figure.

Can I verify a certificate with the lab?

Yes. Each certificate names the lab and carries a report number. Contact the lab with the report number to confirm it issued the report.
