Sermorelin is a synthetic peptide made up of the first 29 amino acids of growth hormone-releasing hormone (GHRH), a naturally occurring hormone produced by the hypothalamus. It works by binding to GHRH receptors in the pituitary gland, signaling the pituitary to produce and release more of your own natural human growth hormone (HGH). Unlike synthetic HGH injections, which introduce exogenous hormones directly into the bloodstream, sermorelin works within your body's own hormonal feedback system — meaning your pituitary gland retains full control over how much growth hormone is released and when.
Originally developed in the 1970s and used clinically for decades, sermorelin has become one of the most widely prescribed peptide therapies in the hormone optimization space. It is administered as a subcutaneous injection — a small, virtually painless injection just below the skin — following a simple
sermorelin injection instructions protocol provided by your telehealth provider, typically in the abdomen, upper thigh, or outer arm. Most physician-guided sermorelin protocols call for a consistent
sermorelin injection frequency of daily injections taken before bed, timed to align with the body's natural peak HGH secretion window during deep sleep.
Sermorelin injection dosage typically ranges from 200mcg to 500mcg per day, with your prescribing physician determining the right starting dose based on your age, weight, IGF-1 levels, and health goals. For patients researching delivery options, our

Sermorelin is a compounded prescription medication, meaning it must be prescribed by a licensed physician following an online or in-person consultation. It is compounded in U.S. licensed pharmacies and shipped directly to patients through telehealth programs — making access to physician-guided sermorelin therapy convenient whether you find a local provider or search for
sermorelin injections near me online. Because sermorelin stimulates natural hormone production rather than replacing it, many patients and providers consider it a safer and more physiologically balanced approach to growth hormone support compared to direct HGH therapy — particularly for adults experiencing age-related declines in energy, muscle tone, sleep quality, and body composition.
