Growth Hormone Secretagogue
Overview

A long-acting somatostatin analog FDA-approved for acromegaly and gastroenteropancreatic neuroendocrine tumors. Administered as a deep subcutaneous depot injection once monthly.

A synthetic analog of growth hormone-releasing hormone (GHRH) that is FDA-approved for HIV-associated lipodystrophy. One of the few peptides with a clear FDA-approved indication, making it a useful reference point for the broader GHRH analog class.

Mechanism of Action

Binds primarily to somatostatin receptor subtypes 2 and 5 (SSTR2, SSTR5), inhibiting growth hormone secretion, reducing IGF-1 levels, and suppressing tumor growth in neuroendocrine tumors.

Binds to GHRH receptors on the pituitary gland, stimulating pulsatile GH release. Reduces visceral adipose tissue (VAT) through GH-mediated lipolysis. Maintains the natural pulsatile pattern of GH secretion, preserving feedback mechanisms.

Common Uses
  • Acromegaly
  • Gastroenteropancreatic neuroendocrine tumors (GEP-NETs)
  • Carcinoid syndrome
  • HIV-associated lipodystrophy (FDA-approved)
  • Visceral fat reduction
  • Metabolic health improvement
  • Growth hormone optimization (off-label)
  • Cognitive function (emerging research in older adults)
Known Risks
  • GI side effects (diarrhea, abdominal pain)
  • Gallstones
  • Injection site reactions
  • Hyperglycemia
  • Bradycardia
  • Injection site reactions (common)
  • Fluid retention and edema
  • Arthralgia (joint pain)
  • Potential glucose metabolism effects
  • Contraindicated in active malignancy
Regulatory Status
FDA Approved

FDA-approved as Somatuline Depot (2007) for acromegaly and GEP-NETs. Administered as a deep subcutaneous injection in the gluteal region once every 4 weeks.

FDA Approved

FDA-approved as Egrifta (tesamorelin for injection) in 2010 for reduction of excess abdominal fat in HIV-infected patients with lipodystrophy. Also available through compounding pharmacies for off-label use with a physician prescription.
