What is Sermorelin?
Sermorelin (GHRH 1-29) is a synthetic peptide that represents the first 29 amino acids of endogenous human growth hormone-releasing hormone. It stimulates the pituitary gland to produce and release growth hormone naturally. Researchers study it as an alternative to exogenous GH administration.
Research Dosing Parameters
- Typical dose range: 200–500 mcg per injection
- Common vial size: 3 mg or 9 mg
- Reconstitution: 1–3 mL bacteriostatic water
- Injection frequency: Once daily, typically at night in research protocols
How to Reconstitute Sermorelin
- Use bacteriostatic water for reconstitution
- Inject water slowly along the inner vial wall
- Gently swirl until dissolved — never shake
- Store at 2–8°C after reconstitution
- Use within 30 days; avoid freeze-thaw cycles
FAQ
How does Sermorelin differ from synthetic GH? Sermorelin stimulates the pituitary to produce GH naturally, preserving normal pulsatile GH secretion patterns. Exogenous GH directly introduces growth hormone and may suppress natural production.
Can Sermorelin be combined with GHRPs? Yes, Sermorelin (a GHRH analogue) is frequently studied in combination with GHRPs like GHRP-2, GHRP-6, or ipamorelin for synergistic GH release. Use the multi-peptide calculator feature above.
