Overview
Tesamorelin Overview: Synthetic GRF(1-44) Peptide Analog
Tesamorelin is a synthetic 44-amino-acid peptide catalogued by livvmore as a reference material for laboratory research. It is a stabilized analog of the naturally occurring releasing factor GRF(1-44), engineered with an N-terminal modification that improves its molecular stability in aqueous conditions. Every vial is documented by batch, with identity and analytical data recorded on the accompanying certificate of analysis.
Supplied as a lyophilized powder in a 10 mg presentation, tesamorelin (CAS 218949-48-5) is offered strictly as a research reagent for in-vitro and laboratory investigation. livvmore does not position it for any other purpose, and its molecular identity, not any outcome, is what defines the listing.
Understanding tesamorelin
Tesamorelin carries a molecular weight of 5135.86 g/mol and belongs to the releasing-factor family of signalling peptides. In neutral molecular terms, researchers study it as a receptor ligand at the GHRH receptor (GHRH-R), a G-protein-coupled receptor expressed on somatotroph cells of the anterior pituitary. The peptide is investigated for how it engages this receptor and for the downstream signalling pathways activated in cellular models.
Its defined amino-acid sequence and the stabilizing modification at the N-terminus make tesamorelin a well-characterised subject for structure-activity work. These structural features are what analytical laboratories confirm by HPLC and LC-MS before a batch is documented and catalogued.
Why tesamorelin is studied
Within the peptide-research community, tesamorelin is a frequently referenced tool compound for exploring the somatotropic signalling axis in controlled laboratory settings. Its consistent identity and improved stability make it a practical model peptide for receptor-level and molecular-pathway research rather than a subject of applied study.

Testing records
What each batch record documents
Every batch is accompanied by laboratory records. The entries below describe what each record documents.
Mass (LC-MS)
Mass spectrometry records the compound’s measured mass to document molecular identity.
Appearance
The physical appearance of the material is recorded, for example a white lyophilized powder.
Batch record
Each batch is logged with a lot number and production date for traceability.
These are records of laboratory testing carried out on the batch. They document compound identity for research use and are not a statement of safety, suitability, or fitness for any use.
Research information
Tesamorelin research context
Scientific interest in tesamorelin centres on its identity as a stabilized GRF(1-44) analog and its interaction with the GHRH receptor. Laboratory investigation typically approaches the peptide through in-vitro and cellular models, focusing on receptor engagement, signalling-pathway characterisation, and analytical confirmation of peptide identity. livvmore supplies tesamorelin solely as a documented research reagent to support this kind of molecular work.
Ongoing and historical research areas associated with this class of releasing-factor peptides include:
- Receptor pharmacology of GHRH-R signalling in cultured cell systems
- Somatotropic-axis and IGF-1 pathway research in laboratory models
- Lipid and adipose-tissue biology explored in molecular and in-vitro settings
- Peptide stability, formulation and structure-activity relationships of GRF analogs
- Analytical characterisation by HPLC, mass spec and LC-MS for identity and purity assessment
