Sermorelin is a synthetic peptide analog of growth hormone-releasing hormone (GHRH), used to stimulate the pituitary gland to produce and release human growth hormone (hGH). It’s FDA-approved for diagnosing and treating growth hormone deficiency in children, but it’s also prescribed off-label for adults seeking anti-aging, muscle growth, or recovery benefits. Important: This is general information only. Sermorelin is a prescription medication. Always consult a licensed healthcare provider for personalized dosing, as improper use can lead to side effects like injection site reactions, headaches, or hormonal imbalances. Self-administration without medical supervision is not recommended.

Standard Dosage Guidelines

Dosing varies by age, weight, condition, medical history, and lab results (e.g., IGF-1 levels). It’s typically administered via subcutaneous injection (under the skin) once daily, often at bedtime to mimic natural hGH pulses.

• Reconstitution: Sermorelin comes as a lyophilized powder (e.g., 3–9 mg vials). Mix with bacteriostatic water (typically 2–3 mL per vial) for a concentration of ~1 mg/mL. Use insulin syringes for precise dosing.
• Adjustments: Reduce dose if side effects occur (e.g., flushing, dizziness). Women may need lower doses due to estrogen effects on hGH. Obese patients often require higher mcg/kg.

Evidence and Sources

• FDA Labeling: For pediatric use, 30 mcg/kg nightly (e.g., EMD Serono’s Geref).
• Clinical Studies:
  • A 1997 study in Journal of Clinical Endocrinology & Metabolism used 1 mg nightly in adults, showing 20–30% IGF-1 increase without major adverse events.
  • Review in Clinical Interventions in Aging (2013) supports 200–500 mcg for age-related hGH decline.
• Guidelines: Endocrine Society recommends individualized dosing based on IGF-1 monitoring, not exceeding physiological hGH levels.

Administration Tips

1. Injection Sites: Abdomen, thigh, or upper arm; rotate to avoid irritation.
2. Timing: 30–60 minutes after last meal; avoid carbs/fats beforehand.
3. Storage: Refrigerate reconstituted vials (stable 14–30 days); discard if cloudy.
4. Monitoring: Baseline and follow-up bloodwork for IGF-1, glucose, thyroid.

Potential Side Effects and Warnings

• Common: Pain/redness at site, headache, nausea.
• Rare: Hyperactivity, allergic reactions, or pituitary overstimulation.
• Contraindications: Active cancer, pregnancy, uncontrolled diabetes.
• Legality: Prescription-only in the US; compounding pharmacies common for off-label use.
