— About this compound

What Tesamorelin is

Tesamorelin is a stabilised 44–amino-acid analog of growth hormone-releasing hormone, modified at the N-terminus with a trans-3-hexenoyl group that improves resistance to enzymatic degradation. It is the largest peptide in our catalog and identity is confirmed by LC-MS on every lot.

— Mechanism

How Tesamorelin
has been studied.

Signalling pathways examined in preclinical models. Descriptive of published research directions, not claims of effect.

Receptor

GHRH receptor engagement

Characterised against the growth hormone-releasing hormone receptor, retaining the full 44-residue sequence of the native hormone.

  • Full-length GRF(1-44) scaffold
  • Assessed in receptor binding preparations
  • Compared against native GHRH
Stability

Enzymatic stabilisation

The trans-3-hexenoyl modification at the N-terminus is the structural feature responsible for improved resistance to dipeptidyl peptidase cleavage.

  • N-terminal acyl modification
  • Studied in plasma stability preparations
  • Characterised by LC-MS fragmentation
— Uses & applications

What Tesamorelin is researched for

Endocrine

GH axis models

Used as a full-length GHRH analog reference in preclinical endocrine work.

Analytical

About Tesamorelin

Still unsure? Ask the lab — median response under four hours.

At 44 residues it is by a wide margin the longest peptide in our catalog. Synthesis yield falls and purification difficulty rises sharply with chain length, which is reflected in the price.

Store the sealed vial at −20°C for long-term stability and 2–8°C for short-term handling. Protect from light and avoid repeated freeze-thaw cycles. Compound-specific stability data is printed on the certificate of analysis supplied with the lot.
