The 25-year old full-back is a free agent after his contract with German club Werder Bremen finished at the end of last season and is being heavily linked with a summer shift to Glasgow.
But reports of a trial have forced Boenisch to react negatively after he started all three games at left-back for Poland during the group stages of Euro2012.
"I won't got for a trial. I am not a youth-team player," he said.
"They could see me play during the Euro 2012 Championships."
