What is Tesamorelin?
A synthetic 44-amino-acid analogue of the body's full-length growth hormone-releasing hormone, carrying a fatty-acid modification that slows its breakdown, Tesamorelin is studied for its effects on growth hormone secretion. Research focuses on how the modification resists enzymatic cleavage while the peptide activates the growth hormone-releasing hormone receptor.
- Studied for its activation of the growth hormone-releasing hormone receptor.
- Investigated for its resistance to enzymatic cleavage from the fatty-acid modification.
- Examined in research models for growth hormone secretion.
- Used as a research tool to study long-acting GHRH analogues.
For research use only. Not intended for human use.
At 44 amino acids, Tesamorelin represents the longest and most structurally complex synthetic GHRH analogue routinely encountered in preclinical receptor pharmacology research. Also designated TH9507 (CAS 218949-48-5), the compound carries a molecular weight of 5134.66 g/mol. Its defining feature is an N-terminal trans-3-hexenoic acid modification investigated for its influence on metabolic stability and GHRHR engagement. Produced via solid-phase peptide synthesis.
In vitro assays using recombinant GHRHR-expressing cell lines have explored the compound's receptor binding affinity and cAMP generation relative to shorter GHRH fragments. In vivo rodent pharmacokinetic studies have characterised the degradation profile of Tesamorelin, investigating whether the hexenoic acid moiety confers measurable resistance to N-terminal enzymatic cleavage.
Manufactured in a quality-controlled laboratory to a guaranteed purity of 98% or above. Every batch undergoes independent third-party testing using HPLC and MS-UPLC analysis before dispatch. Vials are vacuum sealed and stored in a temperature-controlled, monitored cold storage system. A batch-specific Certificate of Analysis is available on request.
Sold strictly for in vitro research purposes only. Not for human consumption. Intended for use by qualified researchers in laboratory settings only.
