Growth-Hormone Research Peptide
Tesamorelin is studied for how the body regulates its own growth hormone. It is a stabilized form of the natural growth-hormone-releasing hormone (GHRH), and in preclinical and metabolic research it is examined as a probe of the growth-hormone axis, including studies with adipose-tissue (including visceral adipose) endpoints.
Type
Synthetic peptide (acylated, 44 residues)
Molecular formula
C221H366N72O67S
Molecular weight
~5,136 g/mol
CAS number
218949-48-5
Amino acids
44
Modification
Full GHRH(1-44) with an N-terminal trans-3-hexenoyl group; C-terminal amide.
A stabilized analogue of human GHRH(1-44) that binds the GHRH receptor (GHRHR), a class B GPCR. The N-terminal trans-3-hexenoyl group distinguishes it from native GHRH.
Research Focus
Studied in GHRH-receptor pharmacology and preclinical metabolic and body-composition research.
Lyophilized
-20°C (-80°C extended)
typically stable 24-36 months desiccated.
Reconstituted
2-8°C short-term
-20°C/-80°C for longer storage.
Avoid freeze-thaw; aliquot; protect from light and moisture. Contains an oxidation-sensitive methionine.
