Characterization

What it is, stated plainly.

What it is

A synthetic analogue of human growth-hormone-releasing hormone (GHRH 1–44) carrying a trans-3-hexenoyl group at the N-terminus, a modification that resists enzymatic clipping at that end. It is an agonist at the GHRH receptor, a class B G-protein-coupled receptor. Published work sits in the somatotropic-axis literature.

How a lot is verified

Identity confirmed by and mass-spec; purity assayed by third-party , with a certificate of analysis published where tested. A lot that misses spec is rejected.

Handling & storage

Supplied as a lyophilized powder. Store at −20°C, desiccated and protected from light. Handled per the receiving laboratory's protocols. Not for human consumption.

Also known asTH9507 · TH-9507 · GHRH(1-44) analog · Trans-3-hexenoyl-GHRH(1-44)-NH2

Tesamorelin is a synthetic analogue of human growth-hormone-releasing hormone — a 44-residue GHRH(1-44) peptide bearing an N-terminal acyl (trans-3-hexenoyl) modification that stabilizes it against enzymatic degradation — supplied as a lyophilized powder for laboratory research use only.

It is a growth-hormone-axis research peptide (a growth-hormone-releasing-hormone analogue); the characterization here reflects the research literature only.

Reported mechanism · literatureCharacterized in the research literature as a growth-hormone-releasing-hormone analogue stabilized against N-terminal enzymatic degradation; the summary reflects that literature only.

Questions

Answered straight.

What is Tesamorelin?

Tesamorelin is a synthetic analogue of human growth-hormone-releasing hormone (a stabilized GHRH(1-44) peptide). Ouralus supplies it as a lyophilized powder for laboratory research use only.

What is the molecular formula of Tesamorelin?

The reported molecular formula is C221H366N72O67S (molar mass ≈ 5136 g/mol; PubChem CID 16137828, CAS 218949-48-5). It is a 44-residue growth-hormone-releasing-hormone (GHRH 1-44) analogue with an N-terminal acyl modification.

Who can order?

These materials are supplied strictly for laboratory and research use, to purchasers of legal age. They are not supplements, drugs, or foods, and are not for human or animal consumption.

Is Tesamorelin legal to buy?

Tesamorelin is supplied strictly as a research chemical for laboratory research use only — it is not a drug, supplement, or food, and not for human or animal consumption. It ships to purchasers of legal age for research use. Buyers are responsible for compliance with the laws that apply to research materials in their own jurisdiction.

Is a certificate of analysis provided with Tesamorelin?

Yes — each tested lot of Tesamorelin ships with a third-party HPLC certificate of analysis from Janoshik, independently verifiable by lot (verify key 7QP6JH56B1AJ). The current lot assayed 99.366%. We publish the certificate before making any purity claim; this is a research chemical for laboratory use only.
