Tesamorelin

Tesamorelin is a synthetic analog of human growth hormone-releasing hormone (GHRH): the full 44-residue GHRH(1-44) amide sequence carrying a trans-3-hexenoyl group on its N-terminal tyrosine, developed under the code TH9507.^{17214611, 19243281} This listing is a single 10 mg vial of lyophilized peptide for qualified laboratory research. The batch certificate for the current lot is posted on this page, so you can check identity, quantity and purity data before ordering.

Compound identity

The two sets of numbers describe the same peptide: the certificate references the acetate salt record, while PubChem’s main tesamorelin entry is the free peptide. The difference of C₂H₄O₂ (about 60 g/mol) is one acetic acid.

Research literature

Tesamorelin (TH9507) is a synthetic 44-residue analog of GHRH(1-44) carrying a trans-3-hexenoyl group at the N-terminus, studied as a ligand of the GHRH receptor.

Batch documentation

The certificate card on this page shows batch RRL-1700427-P, purity 99.39%, dated 27 JUN 2026, from horizonanalytical.com. The linked purity PDF lists lab receipt on 06/23/2026 and analysis on 06/27/2026 by ultra-high-performance liquid chromatography with mass spectrometry (UPLC-MS). Against a 10 mg specification it reports 10.21 mg, with purity at 99.39% against a >98% specification. The endotoxin PDF for lot RRL-1700427-E reports <0.05 EU/mL. Both reports state they can be searched at horizonanalytical.com.

To match a vial to its paperwork, compare the lot printed on the vial label with the lot on the card and the PDF, then confirm the report with the lab. Batch certificates are posted when available, and the store’s posted certificates are collected by product in the COA library. Our guide on how to verify a peptide COA walks through each check.

Storage and handling

Lyophilized peptides keep best sealed, cold, dry and away from light until the laboratory is ready to work with them. Let the vial reach room temperature before opening to limit condensation. Reconstitution solvent is not included: reconstitution solution is listed as a separate item. Handle the material only in a controlled lab with appropriate PPE. For general practice, see peptide storage basics for research labs.

Frequently asked questions

What is tesamorelin?

Tesamorelin (development code TH9507) is a synthetic 44-amino-acid analog of human growth hormone-releasing hormone, GHRH(1-44) amide, with a trans-3-hexenoyl group added to the N-terminal tyrosine. PubChem lists the peptide under CID 16137828 (CAS 218949-48-5). This vial is supplied for laboratory research use only.

What does the certificate for this vial show?

The posted Horizon Analytical certificate for lot RRL-1700427-P reports a UPLC-MS analysis conducted 06/27/2026: tesamorelin identified, 10.21 mg measured against a 10 mg specification, and 99.39% purity. A companion endotoxin report, lot RRL-1700427-E, lists a result of <0.05 EU/mL.

How is this vial different from the Tesamorelin pen listing?

Both listings concern the same compound. This page is the 10 mg lyophilized vial, which the laboratory reconstitutes itself. The pen listing is a pre-filled format offered in 10 mg and 30 mg fills, with its own handling considerations.

How should the lyophilized vial be stored?

Keep the sealed vial cold, dry and protected from light, following the label and your laboratory SOPs. Reconstitution water is sold separately, and reconstituted material should be handled under your institution’s protocols.
