Research-Grade Compound

Tesamorelin is a synthetic analog of growth hormone-releasing hormone (GHRH), built on the full 44-amino-acid GHRH sequence and stabilized by a trans-3-hexenoyl modification at the N-terminus. Molecular formula C221H366N72O67S, molecular weight 5,135.9 Da, CAS 218949-48-5. It is also catalogued as TH9507.

Purity standard: Tesamorelin is sourced to ≥99% by HPLC — sourcing spec.

Buying Tesamorelin — Frequently Asked Questions

What purity standard does Peptide.Express use for tesamorelin?

Sourced to a ≥99% HPLC specification. Where a certificate reports a mass, compare it with the 5,135.9 Da molecular weight. Mass confirmation matters more than usual for a peptide of this size, because truncation products from incomplete synthesis are the most common contaminant in long sequences and they can be difficult to resolve chromatographically.

Where is the Certificate of Analysis for tesamorelin?

On this page and in the Peptide.Express lab results library. Sourced against a ≥99% HPLC purity specification. Third-party Certificates of Analysis are published where on file. The batch number printed on the vial label maps to a specific CoA.

What testing does tesamorelin undergo before shipping?

Where a certificate is on file, it shows the assays that laboratory reported. Those can include reverse-phase HPLC, LC-MS/MS, an endotoxin result, and visual QC. A missing line is not a pass and is not proof the assay never ran.

How should tesamorelin be stored before and after reconstitution?

Lyophilized: -20°C, desiccated, protected from light, stable for 24 months from manufacture. Reconstituted: 2–8°C, used within 14–28 days. Do not freeze the reconstituted solution — freeze-thaw cycling drives aggregation in peptides of this size faster than it does in short sequences.

Is tesamorelin FDA approved?

Yes, as the drug product Egrifta, for the reduction of excess visceral abdominal fat in HIV-infected patients with lipodystrophy. That approval covers a manufactured pharmaceutical for a specific indication in a specific population — it does not extend to research-grade tesamorelin, and the material Peptide.Express supplies is sold strictly for in-vitro laboratory research.
