CJC-1295 W-DAC 2mg is a synthetic analog of human growth hormone-releasing hormone (GHRH) containing a drug affinity complex (DAC). This complex enables the covalent binding (conjugation) of CJC-1295 to endogenous albumin. As a result, the half-life of CJC-1295 is extended to a duration similar to that of albumin. This specific characteristic allows CJC-1295 to have an extended half-life and prolonged effects within the body1. Animal studies have shown that a single administration of CJC-1295 can lead to sustained elevation of insulin-like growth factor-I (IGF-I) levels in the bloodstream, even several days after the initial dose.2
CJC-1295 has been extensively studied in animal models to evaluate its impact on growth hormone secretion, body composition, and metabolism. It is primarily used to enhance levels of endogenous growth hormone by increasing the pulsatile release of growth hormone from the pituitary gland.1 Alba et al. conducted a research study to explore the impact of extended treatment with CJC-1295 on somatotroph cell proliferation, growth hormone production, and IGF-I secretion, as well as growth and body composition in GHRH knockout mice.3 In this study, three groups of one-week-old GHRH knockout mice were subjected to a five-week treatment regimen with 2 μg of CJC-1295 administered at intervals of 24, 48, and 72 hours. GHRH knockout animals that received daily doses of CJC-1295 showed normal body weight and length. However, mice treated every 48 and 72 hours exhibited higher body weight and length compared to the placebo-treated animals. These results show the potential of
CJC-1295 peptide for use in body composition and growth studies in labs.
Further, studies indicate that exogenous administration of growth hormone secretagogues or growth hormone analogs is enough to cause appropriate ovulation. In one such study, to investigate growth hormone’s direct effects on ovarian cells, granulosa cells from rats were cultured with follicle-stimulating hormone (FSH) in the presence or absence of growth hormone. Growth hormone enhanced FSH-induced LH receptor formation, steroid production, and cAMP production in granulosa cells. It increased luteinizing hormone (LH) receptor content by elevating receptor numbers, not affinity. Growth hormone also enhanced FSH-stimulated progesterone production but not estrogen production.5These findings suggest that growth hormone plays a regulatory role in ovarian follicular growth and pubertal development by augmenting gonadotropin-stimulated differentiation of granulosa cells.
