I want to conduct an experiment using the seeds of Ceratonia siliqua but the species is not growing in my country so I didn't find any local supplier.

The seed must be untreated, as this fact is very important for my experiment so I'm worried about buying online without a recommendation. I'm also concerned about possible scams or confusions with seeds of Gleditsia triacanthos which is more common and widespread.

I'm looking for a supplier that can deliver in Romania.

Also, if anyone from the native range of the species can send me 15-20 seeds, I would really appreciate it.
