01 /What it is
Endomorphin-2 is an endogenous tetrapeptide (Tyr-Pro-Phe-Phe-NH2) discovered alongside Endomorphin-1 in the late 1990s. It is a reference ligand in selective mu opioid receptor research.
02 /How it works
In research models, Endomorphin-2 is studied as a highly selective agonist at the mu opioid receptor. It is investigated in receptor selectivity research and in central nervous system signaling research, often in parallel with Endomorphin-1.
03 /What researchers explore it for
Researchers have explored Endomorphin-2 in mu opioid receptor research, in central signaling research, and in receptor selectivity research alongside Endomorphin-1.
04 /Safety and interactions
Research interactions of note include receptor level overlap with other endogenous opioid peptides. Endomorphin-2 is for laboratory research use only and is not for human consumption. Not medical advice. Not intended to diagnose, treat, cure, or prevent any disease.
05 /Research notes
Peptide family: endogenous opioid tetrapeptides. Frequently compared with Endomorphin-1. The Apothify library lists Endomorphin-2 for encyclopedia coverage only.
