Summary
Marketed only as a research chemical with potency reported as 2-5 times that of fentanyl. Reported solubility approximately 3 mg/mL in 10% ethanol/PG solution. Users stress volumetric dosing and allergy testing because a 10-fold error spans the entire active range. Comparable subjective warmth to traditional opiates but with longer duration and less histamine-mediated itching.
