Metabolic Research Peptides
Preclinical research on peptide mechanisms in lipolysis, energy expenditure, and body composition models.
Growth Hormone and Fat Metabolism
Growth hormone (GH) is one of the most potent lipolytic hormones identified in published endocrinology literature. It stimulates the breakdown of stored triglycerides in adipocytes (fat cells) through activation of hormone-sensitive lipase, and is associated with shifts in fuel utilisation toward fatty acid oxidation in research models. GH secretagogues — peptides that stimulate pituitary GH release — are among the most studied compounds in body composition research.
CJC-1295 and Ipamorelin for GH Release
CJC-1295 (no DAC) is a modified GHRH analogue that stimulates pituitary GH release. Ipamorelin is a selective ghrelin receptor agonist (GHSR-1a) that produces clean GH pulses without significant cortisol or prolactin elevation. Together, they represent the most widely studied GH secretagogue stack in the research literature. The combination produces synergistic GH elevation — the GHRH signal (CJC-1295) amplifies the ghrelin signal (Ipamorelin) at the pituitary.
Tesamorelin and Visceral Fat
Tesamorelin is a GHRH analogue that has been specifically studied for its effects on visceral adipose tissue (VAT) — the deep abdominal fat surrounding internal organs. In clinical studies for HIV-associated lipodystrophy, in a clinical trial for HIV-associated lipodystrophy (Falutz et al., 2007), tesamorelin was associated with changes in trunk adiposity. This selective action on visceral fat makes it unique among GH-related peptides.
Important Research Context
Metabolic peptide research is conducted within controlled experimental frameworks. The research interest centres on how GH secretagogues interact with lipolytic pathways, fatty acid oxidation, and tissue partitioning in animal and in vitro models. Published studies typically control for dietary and energy intake variables when examining body composition outcomes in rodent models.
