Description:

WARNING: This product is for research use only, not for human or veterinary use.

U-50488 Free Base is a non-peptide, kappa-opioid receptor agonist which has also been found to stimulate the release of adrenocorticotropin (ADRENOCORTICOTROPIC HORMONE) via the release of hypothalamic arginine vasopressin (ARGININE VASOPRESSIN) and CORTICOTROPIN-RELEASING HORMONE.
