An alleged heroin dealer told undercover police officers in Belfast to ignore the "Russian stuff" and buy from him, the High Court has heard.
Francis Notarantonio sold the Class A drugs to officers posing as users three times in a week, prosecutors claimed.
The 31-year-old, of Elgin Street in the city, faces 16 charges including dealing heroin, acquiring criminal property, and having a stun gun.
Notarantonio was arrested in April after he made contact with two undercover officers on Botanic Avenue in Belfast in January, a bail application hearing was told.
The accused later sent a text saying he had "nice stuff" if the officers were looking for it, she alleged.
Wraps of heroin were then sold for £25 each on three separate dates, the court heard.
He also told the officers "that the Russian stuff was not good", a prosecutor said.
The hearing was adjourned for medical evidence about his efforts to get treatment.
