Tesamorelin 10mg | NeuroPept Labs

Tesamorelin 10mg is a synthetic 44-amino-acid analogue of growth hormone-releasing hormone (GHRH), studied extensively in metabolic and endocrine research. Through an N-terminal trans-3-hexenoyl modification, Tesamorelin achieves enhanced molecular stability and resistance to enzymatic degradation compared with native GHRH, making it a widely used tool compound for investigating pulsatile growth hormone secretion, IGF-1 signalling, and visceral adipose tissue biology.

NeuroPept Labs supplies Tesamorelin 10mg as a research-grade lyophilized peptide intended strictly for in vitro laboratory and analytical research use. All batches are synthesised under controlled conditions and verified through third-party analytical testing. COA validity can be confirmed at freedomdiagnosticstesting.com using the Accession Number, Client ID, or Search Code found in the product images.

Tesamorelin Mechanism of Action (Research Overview)

Tesamorelin is posited to mimic native GHRH by binding GHRH receptors on anterior-pituitary somatotrophs, initiating an intracellular signalling cascade:

• cAMP production — stimulates adenylate cyclase, raising cyclic adenosine monophosphate levels
• PKA activation — elevated cAMP activates protein kinase A, a key signal-transduction enzyme
• Growth hormone secretion — the cAMP-PKA cascade promotes synthesis and pulsatile release of endogenous growth hormone
• IGF-1 elevation — hepatocytes respond to released GH by synthesising insulin-like growth factor-1, the primary anabolic mediator
• Enhanced stability — the trans-3-hexenoyl group reinforces the peptide against enzymatic breakdown, extending its research half-life

Research Applications

Current laboratory and preclinical investigation using the peptide spans multiple research domains:

• Visceral adipose tissue research — lipodystrophy models measuring reductions in visceral and trunk fat
• Hepatic fat and NAFLD research — non-alcoholic fatty liver disease models tracking hepatic fat fraction
• GH/IGF-1 axis biology — pulsatile secretion dynamics and IGF-1 response
• Metabolic and lipid research — triglyceride and cholesterol profiles, insulin sensitivity endpoints
• Body composition and lean mass — imaging-based analysis of muscle density and fat distribution

Frequently Asked Questions

What is Tesamorelin?

It is a stabilized synthetic analogue of growth hormone-releasing hormone (GHRH), and binds GHRH receptors on pituitary somatotrophs to promote pulsatile growth hormone secretion and downstream IGF-1 production, and is widely studied in visceral-fat and metabolic research.

How is Tesamorelin different from native GHRH?

The peptide adds an N-terminal trans-3-hexenoyl group to the GHRH(1-44) sequence, substantially increasing resistance to enzymatic degradation and extending its functional half-life relative to native GHRH in research models.

Is Tesamorelin studied alongside Ipamorelin?

Yes. Tesamorelin (a GHRH-receptor agonist) and Ipamorelin (a GHS-R1a/ghrelin-receptor agonist) act on complementary pathways of the growth hormone axis, and are frequently combined in dual-pathway secretion research.

What purity is NeuroPept Labs’ Tesamorelin 10mg?

Our Tesamorelin 10mg research peptide is supplied at >99% purity, verified by HPLC and third-party analytical testing. Full COA documentation is available for every batch and can be verified at freedomdiagnosticstesting.com.
