Does your country have something like the Analog act? The thing with gray area drugs is that they are usually analogs of existing drugs and someone could conceivably be charged with a crime for having them. It is just that there may not be existing legal precedent for doing so.
I'm afraid we don't allow drug suggestion threads and we generally don't give legal advice because there is a high risk of getting it wrong. Please familiarise yourself with the links in my signature as they will help you get the most out of PD
