GRF (1-44) package: 2mg/vial
GRF (1-44) is a peptide of 44 amino acids. Research studies have shown that in most species GRF 1-44 stimulates the release and synthesis of growth hormone. GRF is synthesized by neurons in the arcuate nucleus of the hypothalamus. After being released into the pituitary portal circulation, it stimulates GH release by the somatotrophs in the pituitary gland.
