Sermorelin vs HGH: What's the Difference?
Both sermorelin and human growth hormone relate to the body's growth hormone axis — but they work very differently. Here's what patients should understand.
What Is Human Growth Hormone (HGH)?
Human growth hormone (HGH) is produced by the pituitary gland and plays a role in metabolism, muscle mass, bone density, and recovery. Levels decline with age, which has led to interest in optimization therapies.
What Is Sermorelin?
Sermorelin is a growth hormone-releasing hormone (GHRH) analog — meaning it signals the pituitary gland to produce and release more of your own natural growth hormone, rather than introducing external HGH directly.
Key Differences
Synthetic HGH directly replaces the hormone. Sermorelin stimulates natural production, which may result in more physiologic release patterns. Both require a prescription and clinical oversight. Neither is appropriate for everyone, and neither is without potential risks.
