How Peptides Work

Peptides are short chains of amino acids that act as signaling molecules. Each one in our catalog is selected for a specific pathway: tissue repair, growth hormone release, metabolic regulation, or cellular longevity.

Quality and testing

From Synthesis to Certificate

Solid-phase synthesis, HPLC purification, mass-spectrometry identity confirmation, lyophilization, sealed vial. Every lot is tested by Janoshik Analytical, an independent third-party lab, and carries a certificate of analysis.

For now, certificates are issued to our supplier, who submits each lot for testing. The COA covers the same lot as your vial, matched by lot number, but lists the supplier as the client rather than Vectra. We plan to submit our own vials so future certificates carry the Vectra name.

01SynthesisSolid-phase, amino acid by amino acid.

02HPLC purificationPurity measured, above 99% or it does not ship.

03Mass spec identityMolecular weight confirmed against reference.

04Third-party COATested by Janoshik Analytical, matched by lot number.

Terms You Will See

HPLC: High-performance liquid chromatography. Measures purity.
COA: Certificate of analysis. Lab results for a specific lot.
Lyophilized: Freeze-dried powder form for stability.
Secretagogue: A compound that prompts the body to release another substance.
