Ipamorelin

Ipamorelin is a synthetic pentapeptide, five residues long and one of the smallest growth hormone secretagogues in common laboratory use. Unlike the GHRH analogues it is often compared against, it acts at the ghrelin receptor GHS-R1a rather than the GHRH receptor. Its compact sequence and reported receptor selectivity are the reasons researchers reach for it when isolating that pathway from adjacent ones.

It ships as a lyophilised powder in a sealed glass vial in a 10 mg presentation. Every lot is accompanied by a Certificate of Analysis recording identity and chromatographic purity. Sold as a laboratory reference material for research use only, and not for human or veterinary use.

Ipamorelin is frequently used as a selectivity control in secretagogue pharmacology. Published research explores:

• Binding affinity and functional potency at GHS-R1a relative to other secretagogues
• Selectivity profiling against receptors implicated in off-target signalling by earlier compounds
• Calcium mobilisation and inositol phosphate readouts in receptor-expressing cell lines
• Comparative studies pairing GHS-R1a agonism with GHRH receptor agonism in animal models
• Structure-activity work on how the pentapeptide scaffold tolerates substitution

Each of these is an area of scientific investigation described in the literature, not a claim of effect. Elements DNA supplies this compound for in vitro and preclinical laboratory research only.
