Sermorelin

Sermorelin Acetate

Sermorelin is a synthetic analog of growth hormone-releasing hormone (GHRH) consisting of the first 29 amino acids of the naturally occurring 44-amino-acid GHRH molecule. It was previously FDA-approved for diagnosing and treating growth hormone deficiency in children. It stimulates the pituitary to produce and release GH in a natural, pulsatile manner.
Reported Benefits

Potential Benefits

  • Stimulates natural GH production through the pituitary gland
  • Has prior FDA-approval history, providing more clinical safety data than many peptides
  • May support improved sleep quality and recovery
  • Research suggests potential benefits for body composition over time
  • May support bone density maintenance in aging populations
Research Dosing

Recommended Starting Dose

200-300 mcg subcutaneously at bedtime

Based on published research protocols. Not a prescription.

Dosing Protocol

Typically injected subcutaneously once daily at bedtime to align with natural GH secretion patterns. Doses range from 200-500 mcg. Cycles of 3-6 months are common in clinical settings, sometimes with periodic breaks.
