Sermorelin is a synthetic peptide analog of growth hormone-releasing hormone (GHRH), consisting of 29 amino acids. It stimulates the pituitary gland to produce and release growth hormone (GH), which supports growth, metabolism, and tissue repair. Unlike anabolic steroids like Anadrol or Anavar, Sermorelin is a peptide used primarily in medical settings for growth hormone deficiency (GHD) and, in research or off-label contexts, for anti-aging, recovery, and body composition optimization. It is often compared to peptides in blends like Klow (e.g., BPC-157, TB-500) but focuses specifically on GH stimulation.
