About the compound

What is Tesamorelin?

Tesamorelin is a stabilised synthetic analogue of growth-hormone-releasing hormone, engineered with a modification that gives it greater stability than the native GHRH peptide. It carries CAS number 218949-48-5 and a molecular weight of 5195.85. As a well-characterised GHRH analogue, it appears widely in growth-hormone and metabolic research as a reference compound, valued for its structural robustness relative to unmodified releasing hormone in study systems.

Mechanistically, tesamorelin acts as a GHRH-receptor agonist and, in experimental models, is reported to stimulate the pituitary release of growth hormone. Its stabilising modification is described in the research literature as improving resistance to enzymatic degradation compared with native GHRH, which extends its usable profile in study systems. This durability is central to why it serves as a benchmark GHRH analogue in much laboratory work.

Within growth-hormone and metabolic research, tesamorelin is studied for its GHRH-analogue activity and its reported effects on growth-hormone axis behaviour across laboratory and clinical-research literature. Its stability makes it a frequent reference point when comparing releasing-hormone analogues. Laboratories sourcing Tesamorelin UK stock commonly cite this well-established body of work when designing controlled endocrine and metabolic experiments under defined conditions.

Sova Peptides supplies tesamorelin as a lyophilised research material for in-vitro and laboratory study by qualified researchers. Each batch is characterised by reverse-phase HPLC and ESI mass spectrometry, with a batch-linked Certificate of Analysis available to confirm identity and molecular weight. Standard lyophilised-peptide storage and handling apply throughout. This product is supplied strictly for laboratory research use only and is not for human or veterinary use.

FAQ

Tesamorelin, answered.

What is Tesamorelin?

+

Tesamorelin is a stabilised synthetic analogue of growth-hormone-releasing hormone, modified for greater stability than native GHRH. It has CAS number 218949-48-5 and a molecular weight of 5195.85, and is used in laboratory research as a well-characterised GHRH-analogue reference compound.

Is Tesamorelin legal to buy in the UK?

+

Tesamorelin is not offered as a licensed medicine in the UK and is supplied strictly as a research chemical for laboratory use only. Purchase and supply for that purpose are permitted when it is not marketed for human consumption, with compliant handling the responsibility of the purchasing researcher or institution.

What is Tesamorelin studied for?

+

Tesamorelin is investigated in the research literature for its GHRH-analogue activity and its reported influence on the growth-hormone axis and related metabolic parameters in laboratory and clinical-research models. This body of work is scientific in nature and is described here purely to convey the compound's research context.

How is Sova's Tesamorelin verified?

+

Each batch of Sova's tesamorelin is analysed by reverse-phase HPLC for identity and by ESI mass spectrometry to confirm its molecular weight against the expected 5195.85. A batch-linked Certificate of Analysis accompanies every lot so researchers can verify the specific material supplied.

How should Tesamorelin be stored?

+

Lyophilised tesamorelin is typically kept cold and away from light, refrigerated for short periods and frozen for longer-term storage. Once reconstituted for research, solutions are generally refrigerated and used within a limited window, with containers sealed to limit moisture and repeated freeze-thaw cycling.

What distinguishes Tesamorelin among GHRH analogues?

+

What distinguishes tesamorelin is its engineered stability: a structural modification improves its resistance to enzymatic breakdown relative to native GHRH, giving it a more durable profile in research systems. This robustness is a major reason it is used as a benchmark releasing-hormone analogue in the literature.
