What is Tesamorelin?

Tesamorelin is a synthetic 44 amino acid analogue of growth hormone releasing hormone, GHRH (1-44). It binds GHRH receptors on pituitary somatotrophs and is used as a reference compound in cAMP accumulation and PKA signalling assays. NuVion stocks it in Australia in 10mg and 20mg vials.

  • Synthetic 44 amino acid GHRH (1-44) analogue
  • Binds GHRH receptors on pituitary somatotrophs
  • Used in cAMP accumulation and PKA signalling assays
  • Supplied lyophilised, purity by RP-HPLC and identity by mass spectrometry

Tesamorelin structure and research use

Tesamorelin keeps the full 44 amino acid sequence of human GHRH and adds a trans-3-hexenoic acid group to the N-terminal tyrosine, a modification that slows enzymatic cleavage at that end of the chain. It acts at the GHRH receptor, a class B G protein-coupled receptor that signals through Gs, cyclic AMP and protein kinase A. In the laboratory it serves as a reference agonist in somatotroph culture and somatotropic axis research.

Tesamorelin vial sizes and prices, 10mg and 20mg

NuVion stocks tesamorelin in 10mg and 20mg vials. Both hold the same lyophilised peptide, and the 20mg vial works out cheaper per milligram.

Tesamorelin research applications

  • Cyclic AMP accumulation by HTRF, AlphaScreen or reporter in cell lines expressing the GHRH receptor
  • Western blot and qPCR measurement of CREB phosphorylation and Pit-1 expression downstream of the receptor
  • Dipeptidyl peptidase 4 stability assays comparing the hexenoyl-modified peptide with unmodified GHRH (1-44)
  • Growth hormone secretion from pituitary somatotroph culture, quantified in conditioned medium by ELISA

Storing and handling Tesamorelin

Before reconstitution
Keep the sealed vial cool, dry and out of direct light. General practice for lyophilised peptides.
After reconstitution
Reconstitute with bacteriostatic or sterile water, store at 2 to 8°C and avoid repeated freeze-thaw cycles. No stability-tested shelf life is published for this product.

Tesamorelin questions

Where can I buy tesamorelin in Australia?
NuVion stocks tesamorelin in Australia in 10mg and 20mg vials. Choose a size at the top of this page and check out, and the order is posted from Australian stock on a tracked express service. This product is supplied as a research material only and is not on the Australian Register of Therapeutic Goods.
How much does tesamorelin cost in Australia?
Tesamorelin is $119 AUD for the 10mg vial and $199 for the 20mg vial. The 20mg vial is the lower price per mg at $9.95.
What is Tesamorelin used for in research?
It is used as the reference full agonist at the GHRH receptor in cyclic AMP accumulation assays, in competition binding to determine affinity for analogues, in growth hormone secretion assays on pituitary cell culture, and in stability comparisons against unmodified GHRH.
How does Tesamorelin work at the cell level?
The GHRH receptor is a class B G protein-coupled receptor expressed on pituitary somatotrophs. Binding follows the two-domain model typical of the class: the C-terminal portion of the peptide docks into the large extracellular domain, which positions the N-terminal region to insert into the transmembrane core and trigger the conformational change that activates the receptor. The Tesamorelin research profile covers the mechanism in full.
What does the hexenoyl group on Tesamorelin do?
It caps the alpha-amino group of tyrosine 1, the residue dipeptidyl peptidase 4 recognises. The trans-3-hexenoyl group is a six-carbon unsaturated acyl chain, and it blocks the peptidase while leaving the residues that contact the receptor unchanged.
What is the molecular mass of Tesamorelin?
Tesamorelin has a molecular mass of 5135.9 g/mol, just over 5 kDa, across 44 residues. In size it sits between the short synthetic peptides and the glycoprotein hormones, and it retains the C-terminal amide of the native (1-44) amide form.
What do HPLC and mass spectrometry detect in Tesamorelin?
Deletion and truncation sequences from solid phase synthesis show in the HPLC trace of a peptide this long. Methionine oxidation and deamidation of asparagine or glutamine appear as closely eluting peaks, with mass shifts of plus 16 and plus 1 respectively.
How is tesamorelin different from CJC-1295?
Both are GHRH analogues that act at the GHRH receptor. Tesamorelin is the full 44 amino acid sequence with a trans-3-hexenoic acid group on the N-terminus. CJC-1295 No DAC is a shortened 29 amino acid analogue with four substitutions.
What form does tesamorelin arrive in?
As a lyophilised (freeze-dried) powder in a sealed vial. Bacteriostatic water is sold separately.
