Sermorelin

Sermorelin is a synthetic peptide reproducing the first 29 amino acids of human growth hormone-releasing hormone. That truncated sequence is the shortest fragment of GHRH known to retain full activity at its receptor, which is why it became a standard laboratory tool for probing the hypothalamic-pituitary axis rather than a longer full-length construct.

It ships as a lyophilised powder in a sealed 10 mg glass vial. Each lot is accompanied by a Certificate of Analysis recording compound identity and chromatographic purity. Material is sold as a laboratory reference standard for research use only and is not for human or veterinary use.

Sermorelin appears in the literature primarily as a reference agonist for the GHRH receptor, a class B GPCR expressed on pituitary somatotrophs. Research topics include:

• Receptor binding affinity and cAMP signalling in somatotroph cell models
• Pulsatile versus continuous receptor stimulation and the resulting secretory patterns in animal models
• Comparison against longer-acting GHRH analogues to isolate the contribution of half-life to signalling
• Enzymatic degradation by dipeptidyl peptidase-4 and strategies for stabilising the N-terminus
