Description
Sermorelin is the biologically active 29-amino-acid fragment of growth hormone-releasing hormone and a foundational compound in endocrine research. Limitless Life Nootropics supplies it as a 5mg lyophilized vial, made in the USA.
What Is Sermorelin?
Researchers discovered in the early 1980s that the first 29 amino acids of the 44-amino-acid GHRH molecule were enough to reproduce its full activity at the pituitary. This shorter fragment, GHRH(1-29)NH2, became known as sermorelin and was studied extensively as a diagnostic and research tool.
Because it is identical to the natural hormone’s active region, it stimulates growth hormone release through the GHRH receptor while remaining subject to normal feedback from somatostatin. Its short half-life makes it a useful reference compound when comparing newer, more stable analogs such as Modified GRF 1-29.
Each Premium lyophilized vial contains 5mg of peptide.
Areas of Scientific Investigation
Laboratory studies have explored this peptide across several areas of investigation:
- GHRH receptor signaling in pituitary models
- Somatostatin feedback and GH pulsatility
- Aging and growth hormone axis research
- Reference comparisons with stabilized GHRH analogs
- Sleep and growth hormone secretion studies
Researchers can review peer-reviewed studies on this compound through the National Library of Medicine (PubMed) database.
