Introduction
Sermorelin (GHRH 1-29 NH2) is one of the most studied growth hormone-releasing hormone analogues in peptide research. As a 29-amino acid fragment of endogenous GHRH, sermorelin has been the subject of extensive preclinical research into the growth hormone axis, pituitary function, and age-related changes in GH secretion.
Understanding Sermorelin's Research Profile
Sermorelin acts as a GHRH receptor agonist, stimulating the anterior pituitary to release endogenous growth hormone in a pulsatile, physiologically regulated manner. Unlike synthetic GH administration, sermorelin preserves the natural feedback mechanisms of the GH axis, making it a valuable tool for studying pituitary responsiveness and GH pulse dynamics.

Key Quality Indicators
Research-grade sermorelin should meet: Purity ≥98% by HPLC; mass spectrometry confirmation of molecular weight (MW: 3357.93 Da); independent COA from an accredited third-party laboratory; and endotoxin testing documentation for cell culture or animal model research.
Comparing Sermorelin to Other GHRH Analogues
Sermorelin has a very short plasma half-life (~10-20 minutes), which makes it useful for studying acute GH pulses. CJC-1295 without DAC (CJC-1295 (No DAC)) has a half-life of approximately 30 minutes, producing a slightly longer but still pulsatile GH response. A separate DAC-modified version of CJC-1295 has a half-life of days, better suited for sustained GH axis stimulation studies — however, Pure Pharm Peptides carries only the no-DAC formulation. See our Sermorelin vs CJC-1295 comparison for a detailed breakdown.
Pure Pharm Peptides Sermorelin
Pure Pharm Peptides supplies sermorelin in 5mg vials (10 vials per kit) with independent USA laboratory COA verification. View the Sermorelin product page for current batch COA and specifications.
