Description:

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

XEP-018, also known as μ-Conotoxin Cn IIIC, is a biomimetic of a natural conopeptide from venomous marine cone snail (Conus consors). Biologically, it acts as a modulator of the neuromuscular transmission, as well as a potent and selective blocker of the voltage-gated sodium channel Nav 1.4. Cosmetically, it acts as an instant line relaxer giving a smooth skin appearance.
