Tesamorelin 20 mg

Q: What is the intended use of this material?

It is supplied for laboratory research and analytical work only and is not intended for human or veterinary use.

Q: Where can the lot documentation be reviewed?

Use the documentation link on this page or the site Lab Tests directory. Where a task-matched current report is shown, that record controls its stated analytical results.

Q: What does an HPLC purity value on the COA represent?

It is a lot-specific analytical measurement reported by the testing laboratory for the sample submitted, and it should not be treated as a permanent value applying to every lot.

Compound: Tesamorelin (trans-3-hexenoyl-human growth hormone-releasing factor (1-44) amide)
CAS: 218949-48-5
Molecular formula: C221H366N72O67S
Molecular weight: 5135.9 Da
Purity: 99.119%Report #216338 · Aug 10, 2026 · submitted sample

Tesamorelin is a synthetic 44-residue C-terminally amidated polypeptide corresponding to the full- length sequence of human growth hormone-releasing factor, carrying a trans-3-hexenoyl group attached to the N-terminal tyrosine. The acyl cap is the sole structural difference from the unmodified 1-44 parent sequence. The molecule is substantially larger than the 1-29 fragment analogues and retains the native methionine residue.

The molecular target is the growth hormone-releasing hormone receptor (GHRHR), a class B G-protein- coupled receptor. Ligand interaction is characterised in GHRHR-expressing recombinant systems by competition displacement binding, generating Ki values specific to that construct. Downstream Gs coupling is recorded as concentration-dependent cAMP accumulation in validated transfected cell lines. Receptor internalisation and desensitisation endpoints are measured separately as prespecified assay readouts.
