Sermorelin

Sermorelin is a synthetic peptide analog of growth hormone–releasing hormone (GHRH). It stimulates the pituitary gland to release endogenous growth hormone (GH), which then increases IGF-1 levels.

Sermorelin (formerly marketed as Geref) was previously FDA-approved for diagnosing and treating growth hormone deficiency in children.

However:

  • The branded product Geref was discontinued in 2008
  • Today sermorelin is commonly obtained through compounding pharmacies
  • Most adult uses are off-label

Sermorelin, although similar to Tesamorelin, has a shorter half life and a milder response.

Potential Benefits

  • Age-related decline in growth hormone
  • Improved body composition
  • Fat reduction
  • Sleep quality improvement
  • Energy and recovery
  • Support for lean muscle mass

Most Common Side Effects

  • Injection site redness or irritation
  • Headache
  • Flushing
  • Dizziness
  • Nausea
  • Mild fluid retention

Contraindications

  • Active malignancy (cancer)
  • Pregnancy
  • Known hypersensitivity

Studies

Most clinical research involving sermorelin focused on growth hormone deficiency diagnostics in children. Evidence supporting use in healthy adults for anti-aging or body composition remains limited.

Example NIH / PubMed Studies on Sermorelin

  1. Growth Hormone Diagnostic Study
    https://pubmed.ncbi.nlm.nih.gov/2869827/

    This study evaluated sermorelin as a diagnostic tool for growth hormone deficiency by stimulating GH release.

  2. Evaluation of Sermorelin in Growth Hormone Deficiency
    https://pubmed.ncbi.nlm.nih.gov/1909937/

    Researchers assessed sermorelin's ability to stimulate GH secretion in pediatric patients with suspected GH deficiency.

  3. Growth Hormone–Releasing Hormone Therapy Study
    https://pubmed.ncbi.nlm.nih.gov/8419608/

    Examined the use of GHRH analogs (including sermorelin) in long-term treatment of growth hormone deficiency.
