Sermorelin Peptide

Sermorelin (Tyr-Ala-Asp-Ala-Ile-Phe-Thr-Asn-Ser-Tyr-Arg-Lys-Val-Leu-Gly-Gln-Leu-Ser-Ala-Arg-Lys-Leu-Leu-Gln-Asp-Ile-Met-Ser-Arg-NH₂) is the bioactive N-terminal fragment of the 44-amino-acid natural GHRH. As documented in peer-reviewed literature, Sermorelin selectively binds pituitary GHRH receptors to stimulate physiological, pulsatile GH secretion while preserving natural feedback loops — unlike exogenous hGH, which suppresses endogenous production (pubmed.ncbi.nlm.nih.gov). Once FDA-approved (1997–2008) for pediatric GH deficiency diagnostics and treatment, it remains a widely referenced compound for research on the adult GH axis. This research-grade lyophilized powder is synthesized under strict quality controls and provided with full analytical documentation. For Research Use Only. Not for human use.

Key Scientific Specifications

• High-purity Sermorelin (≥ 98% by HPLC/MS, acetate salt form)
• Exact 29-amino-acid GRF 1-29 sequence (identical to human GHRH 1-29)
• Lyophilized formulation for maximum long-term stability
• Full Certificate of Analysis (COA) with HPLC, MS, and amino acid analysis
• Manufactured in GMP-aligned, ISO-compliant facilities
• Suitable for pulsatile GH release studies, diagnostic challenge assays, and neuroendocrine research

Research-Referenced Characteristics (Based on published scientific literature; not intended as therapeutic or health claims. For laboratory research use only.)

• Studied for its role in modulating physiological pulsatile GH secretion patterns in GH-deficient and aging research models
• Investigated for dose-dependent, feedback-regulated effects on IGF-1 levels in preclinical models
• Shown to preserve natural GH negative feedback mechanisms in research settings — contrasting with direct hGH administration
• Subject of preclinical and historical studies examining effects on slow-wave sleep architecture and metabolic parameters
• Investigated in research contexts involving skeletal and immune system endpoints
• Used in combination research protocols alongside GHRP peptides (e.g., Ipamorelin, GHRP-2/6) for studies of GH pulse amplification
• Applicable to research investigating pituitary reserve and age-related neuroendocrine axis function
