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.
