What Is Tesamorelin?
Tesamorelin (originally coded TH9507) is the full 44-residue sequence of human growth hormone-releasing hormone with a trans-3-hexenoyl group attached to the N-terminal tyrosine. That single modification protects the peptide from rapid cleavage by dipeptidyl peptidase-4, giving it a substantially longer active life than native GHRH in enzyme and cell systems. Our Tesamorelin 10mg vial has a molecular weight of approximately 5,135.9 Da.
It is one of the most extensively characterised GHRH analogues in the published literature, which makes it a useful comparator in receptor and pituitary studies. The lyophilised format keeps the peptide stable in storage and lets researchers reconstitute to the concentration their protocol requires.
Tesamorelin Research Areas
Laboratory studies of Tesamorelin cover the following areas:
GHRH Receptor Pharmacology
Tesamorelin is used in GHRH-receptor binding and cAMP assays, and as a stabilised comparator to native GHRH and Sermorelin. Published work can be explored on PubMed.
Peptide Stability and Enzyme Resistance
The N-terminal modification makes Tesamorelin a standard model for studying how acylation alters peptidase resistance and plasma stability.
Pituitary Somatotroph Models
Primary pituitary cultures and perfusion systems use the peptide to study sustained growth hormone synthesis and release.
Adipose and Metabolic Models
Preclinical research has examined downstream effects of GHRH-analogue signalling on lipid metabolism and adipose tissue markers.
Tesamorelin vs Sermorelin and CJC-1295
Sermorelin is the unmodified 1–29 fragment of GHRH, CJC-1295 (No DAC) is a 29-residue analogue with four stabilising substitutions, and Tesamorelin is the full 1–44 sequence with an N-terminal acyl group. Researchers select Tesamorelin when they need the full-length sequence with improved enzymatic stability; the shorter analogues are chosen for minimal-sequence studies.

Quality Control and Batch Testing
Every batch of Tesamorelin 10mg is analysed before release. HPLC confirms purity, and mass spectrometry confirms that the peptide mass matches the expected structure. You can view current certificates on our verification and testing page.
Storage and Handling
Store lyophilised Tesamorelin at −20°C for long-term stability, protected from light and moisture. Reconstitute with bacteriostatic water using aseptic technique, then keep the solution refrigerated at 2–8°C and use promptly. See our guides on how to reconstitute peptides and how to store research peptides.
