Tesamorelin 10 mg

Descriere

Tesamorelin is a synthetic analogue of human growth hormone-releasing hormone (GHRH) consisting of the full 44-amino-acid GHRH sequence with structural modifications that improve stability and resistance to enzymatic degradation.

Unlike GHRP peptides, which stimulate the ghrelin receptor (GHSR-1a), Tesamorelin acts directly on the GHRH receptor in the anterior pituitary, promoting physiological pulsatile secretion of endogenous growth hormone. This receptor selectivity has made Tesamorelin one of the most thoroughly investigated peptides in growth hormone physiology and metabolic research.

Why Tesamorelin matters in endocrine research

Tesamorelin differs from many secretagogues because it closely mimics the body’s natural GHRH signalling rather than activating ghrelin pathways.

Published research has investigated Tesamorelin in relation to:

• pulsatile growth hormone secretion
• IGF-1 regulation
• body composition
• visceral adipose tissue
• hepatic fat
• endocrine physiology
• metabolic regulation
• pituitary function

Its extensive human evidence base has established Tesamorelin as one of the best-characterised GHRH analogues available for metabolic and endocrine research.

How Tesamorelin works

Unlike GHRP peptides, Tesamorelin activates the growth hormone-releasing hormone receptor (GHRHR).

Published research has explored its relationship with:

Growth hormone secretion

Tesamorelin stimulates physiological pulsatile release of endogenous growth hormone through direct activation of pituitary GHRH receptors.

IGF-1 regulation

Clinical studies consistently demonstrate increased circulating IGF-1 following Tesamorelin administration, making it an important research tool for GH-axis physiology.

Body composition

A major area of investigation has been the relationship between endogenous GH stimulation and changes in visceral adipose tissue and lean body mass.

Metabolic physiology

Researchers have also investigated hepatic fat metabolism, lipid regulation and broader metabolic adaptations associated with physiological GH release.

Why Tesamorelin is widely investigated in metabolic research

Among growth hormone secretagogues, Tesamorelin occupies a unique position because much of its research has focused on metabolic health rather than growth hormone deficiency alone.

Published studies have explored:

• visceral adipose tissue
• hepatic fat
• body composition
• metabolic syndrome
• IGF-1 physiology
• endocrine regulation
• HIV-associated lipodystrophy

This broad clinical evidence has made Tesamorelin one of the most important peptides for studying the interaction between the growth hormone axis and metabolic physiology.

Human and preclinical research

Tesamorelin has one of the strongest clinical evidence bases among all growth hormone secretagogues.

Multiple Phase III studies have investigated its effects on growth hormone secretion, visceral adipose tissue, lipid metabolism and hepatic fat. Unlike many research peptides, Tesamorelin has also received regulatory approval for one specific clinical indication, resulting in extensive long-term human safety and efficacy data.

How Tesamorelin differs from other GH secretagogues

Tesamorelin

• GHRH analogue
• Direct GHRH receptor activation
• Strong clinical evidence
• Extensive metabolic research

CJC-1295 (No DAC)

• GHRH analogue
• Longer research half-life
• Primarily experimental

Ipamorelin

• Ghrelin receptor agonist
• Selective GH secretagogue
• Minimal appetite effects

GHRP-2

• Potent ghrelin receptor agonist
• Robust GH pulses
• Endocrine physiology

GHRP-6

• Ghrelin receptor agonist
• Appetite and GH research
• Gastrointestinal physiology
• Published safety observations

Published clinical studies have generally reported Tesamorelin to be well tolerated. The most commonly reported adverse events included injection-site reactions, arthralgia, peripheral oedema and transient increases in IGF-1, with gastrointestinal effects occurring less frequently than with many modern metabolic peptides. Safety findings are derived from controlled clinical trials conducted primarily in patients with HIV-associated lipodystrophy.

Product characteristics

Use restriction: not for human consumption; not for medical, veterinary or cosmetic use
Produced in GMP-compliant facilities under strict QC protocols.
Each batch carefully lab tested after production (you can find Certificate of Analysis under product pictures).
Freeze-dried (lyophilized) for maximum stability and extended shelf life.
Sealed in sterile vials, ready for reconstitution.
Purity: ≥ 99% (HPLC)
Appearance: white lyophilized powder
Molecular formula: C₂₂₁H₃₆₆N₇₂O₆₇S
Molecular weight: 5135.78
CAS No: 218949-48-5

Storage: unopened lyophilized vials are best stored refrigerated at 2–8°C, which is the storage method confirmed by our manufacturing partner and suitable for up to 24 months. Refrigeration is preferred because it minimizes unnecessary freeze–thaw cycles during routine handling. If substantially longer-term storage is required, unopened lyophilized vials may also be kept frozen. Once reconstituted, always store at 2–8°C and do not freeze.

Reconstitution and handling

Tesamorelin is supplied as a lyophilised vial and should be handled using standard peptide reconstitution procedures appropriate to the research setting. Must be reconstituted with bacteriostatic water before use. To help preserve structural integrity, add the chosen solvent slowly against the inside wall of the vial rather than directly onto the peptide cake, and avoid vigorous shaking. Gentle swirling is generally sufficient once the peptide has fully dissolved. Standard laboratory practice also includes allowing refrigerated vials to reach room temperature before reconstitution to minimise condensation inside the vial.

Întrebări Frecvente

What is Tesamorelin?

Tesamorelin is a synthetic analogue of human growth hormone-releasing hormone (GHRH). It stimulates the pituitary gland through the GHRH receptor, promoting physiological pulsatile release of endogenous growth hormone. It is widely investigated in endocrine and metabolic research involving the GH/IGF-1 axis, body composition and visceral adipose tissue.

How does Tesamorelin differ from CJC-1295?

Both Tesamorelin and CJC-1295 are GHRH analogues that activate the same receptor pathway. Tesamorelin has an extensive clinical evidence base, including regulatory approval for HIV-associated lipodystrophy, whereas CJC-1295 remains primarily an experimental research peptide. Their receptor mechanism is similar, but their clinical development differs substantially.

How does Tesamorelin differ from Ipamorelin or GHRP peptides?

Tesamorelin stimulates growth hormone release through the GHRH receptor, while Ipamorelin, GHRP-2 and GHRP-6 activate the ghrelin receptor (GHSR-1a). These are complementary physiological pathways, which is why GHRH analogues and GHRP peptides are frequently investigated together in endocrine research.

Why is Tesamorelin widely investigated in metabolic research?

Beyond growth hormone physiology, Tesamorelin has been extensively studied for its effects on body composition, visceral adipose tissue, hepatic fat, lipid metabolism and IGF-1 regulation. This broad clinical evidence distinguishes it from many other growth hormone secretagogues.

What research areas commonly investigate Tesamorelin?

Published studies have investigated Tesamorelin in growth hormone secretion, IGF-1 regulation, pituitary physiology, body composition, visceral adipose tissue, hepatic fat, metabolic regulation and endocrine signalling.

Can Tesamorelin be combined with GHRP peptides in research?

Yes. Because Tesamorelin activates the GHRH receptor while GHRP peptides activate the ghrelin receptor, researchers frequently investigate these pathways together to study complementary mechanisms regulating pulsatile growth hormone secretion. Individual study designs vary, and findings should be interpreted within the context of the published research.
