Tesamorelin 10mg

Tesamorelin is a synthetic 44-amino-acid analogue of human growth-hormone-releasing factor. A trans-3-hexenoyl group is attached at the N-terminus to improve stability relative to native GHRH.

PubChem lists tesamorelin, CAS 218949-48-5, with a molecular weight of approximately 5,136 g/mol and the molecular formula C221H366N72O67S.

Tesamorelin is based on the full 44-amino-acid human GRF sequence and includes an N-terminal modification. Shorter GHRH research peptides use truncated sequences and are chemically distinct compounds.

Peer-reviewed studies have examined GHRH-receptor pharmacology, endogenous GH pulsatility, IGF-1 pharmacodynamics and body-composition endpoints. Those studies do not change this product’s research-use-only status.

The Selected literature section links to controlled studies covering GH pulsatility, pharmacokinetic and pharmacodynamic markers, and phase 3 research in defined study populations.

Every batch goes through three layers of quality control. Our manufacturer runs its own QC and has its production independently tested by Janoshik Analytical. Then Vanguard or Janoshik tests every batch we stock again, for identity, HPLC purity, net content and endotoxins before we approve it for sale.

Every approved batch has its lab report on the Test Results page.

We target 99%+ purity by HPLC. The actual purity of each batch is measured independently and published in its lab report, so you can check the result yourself.

Store the sealed lyophilized vial at -20°C, protected from light, and follow the product label and batch documentation. After reconstitution, use controlled refrigerated laboratory storage at 2-8°C within the defined research window and avoid repeated freeze-thaw cycles.
