Product Description for Tesamorelin (5mg / 10mg)
Tesamorelin is a synthetic 44-amino acid peptide analog of growth hormone-releasing hormone (GHRH). It is designed to stimulate the pituitary gland to release endogenous growth hormone in a physiological, pulsatile manner. In laboratory research, Tesamorelin is primarily investigated for its effects on growth hormone secretion, body composition, and visceral fat metabolism. It serves as a valuable tool for scientists studying endocrine regulation, lipodystrophy models, and age-related hormonal changes.
At Aether Peak Peptides, Tesamorelin is provided in high-purity lyophilized vials for controlled scientific investigations. This GHRH analog is favored in research requiring selective stimulation of the GH axis with minimal impact on other pituitary hormones.

Tesamorelin features a modified N-terminal sequence that enhances its stability and receptor affinity compared to native GHRH in research models.
Mechanism of Action in Research Models
Tesamorelin binds to GHRH receptors on somatotroph cells in the anterior pituitary, activating adenylate cyclase and increasing intracellular cAMP. This leads to pulsatile growth hormone release without significantly affecting other pituitary hormones such as cortisol or prolactin in most experimental settings. Researchers study its downstream effects on IGF-1 production, lipolysis, and body composition parameters.
Key Research Applications
Tesamorelin is commonly used in laboratory investigations including:
- Growth hormone axis regulation and pulsatile secretion studies
- Visceral fat reduction and metabolic research
- Body composition and lipodystrophy models
- Age-related growth hormone decline
- Synergistic effects with other secretagogues
