What is Sermorelin?
Sermorelin is a bioidentical synthetic peptide that contains the first 29 amino acids of human Growth Hormone Releasing Hormone (GHRH). It stimulates the pituitary gland to produce and release growth hormone naturally.
Key Facts
- Type: GHRH analog
- Amino acids: 29 (same as active portion of natural GHRH)
- Mechanism: Stimulates pituitary GH release
- FDA status: Previously FDA-approved (for GH deficiency testing)
How Sermorelin Works
Physiological Mechanism
- Binds to GHRH receptors in pituitary
- Stimulates somatotroph cells
- Triggers natural GH synthesis and release
- Maintains normal feedback loops
Why Natural Stimulation Matters
- Preserves pituitary function
- Maintains feedback regulation
- Avoids exogenous GH side effects
- More physiological hormone levels
