Summary
Sermorelin is a synthetic analogue of the first 29 amino acids of human growth hormone-releasing hormone (GHRH). It stimulates pituitary GH secretion and has been used in pediatric GH deficiency research. Considered a physiological approach to GH augmentation due to preservation of pulsatile release.
Sermorelin is the original GHRH analogue — it's been around since the 1990s and was used clinically for children with growth hormone deficiency. It tells the pituitary to release GH in the same pulsatile way it naturally would, rather than flooding the body with synthetic GH. Very short-acting (clears in minutes), so bedtime injection works with the body's natural overnight GH surge.
Mechanism of Action↓
GHRH receptor agonist. Stimulates somatotroph production and release of GH in a pulsatile fashion. Shorter than native GHRH(1-44) but retains full biological activity.
Half-life: ~11 minutes (rapidly cleaved by plasma dipeptidyl peptidase IV)
Research Dosing Ranges↓
100–300 µg per injection
Once daily at bedtime, subcutaneous
Bedtime administration aligns with natural nocturnal GH pulse.
Reconstitution Guidance↓
BAC water: 3 mL
Resulting concentration: 1.67 mg/mL (for 5 mg vial)
Add 3 mL BAC water to 5 mg vial → 1.67 mg/mL. 200 µg dose = 120 µL = ~12 units U-100.
Storage & Stability↓
Refrigerate lyophilized and reconstituted. Sensitive to heat.
Known Side Effects / Contraindications↓
Flushing, injection site reactions, headache, dizziness. Generally well tolerated in clinical studies.

Concentration: 5 mg ÷ 3 mL = 1.67 mg/mL (1667 µg/mL)
Dose needed: 250 µg = 0.2500 mg
Volume per dose: 0.2500 mg ÷ 1.67 mg/mL = 0.1500 mL
On U-100 syringe: 150.0 µL = 15.0 units
Total doses in vial: 5 mg ÷ 0.2500 mg = 20.0 doses
