CJC1295 is a Long-acting growth-hormone-releasing hormone (GHRH) analog. Because of the long half-life and stability of the CJC1295 analog, it appears to become more and more popular. CJC1295 is a Long acting GHRH analog. Growth-hormone-releasing hormone (GHRH), also known as growth-hormone-releasing factor (GRF or GHRF) or somatocrinin, is a 44-amino acid peptide hormone produced in the hypothalamus by the arcuate nucleus. GHRH stimulates growth hormone (GH) secretion from the pituitary. GHRH is released in a pulsatile manner, stimulating pulsatile release of GH respectively. In addition, GHRH also promotes slow-wave sleep.
