Updated By: Mindful Research Team1 min read

Key takeaways

  • When sourcing tesamorelin, check for a batch-specific COA, HPLC purity, and MS identity.
  • It is studied in vitro as a GHRH analog at the GHRH receptor.
  • A batch COA is tied to your exact lot with dated data.
  • Supplied as a research material with batch documentation.
  • For in vitro research use only.

When sourcing tesamorelin as a research material, what matters is a batch-specific Certificate of Analysis, HPLC purity, and mass-spectrometry identity confirmation. Tesamorelin is a synthetic peptide studied in vitro as a growth-hormone-releasing-hormone (GHRH) analog. This guide covers what to check.

Batch-specific COA

A strong COA is tied to the exact lot you receive, with dated analytical data reporting identity, purity, and methods — not a generic spec sheet.

Purity by HPLC

HPLC separates the sample and reports the percentage that is the target compound; a clean dominant peak indicates high purity.

Identity by mass spectrometry

Mass spectrometry confirms the measured molecular weight matches the expected value, confirming identity. The expected values and common naming mix-ups are laid out in confirming tesamorelin identity by CAS and mass spectrometry.
