Off-topic: I noticed you're from Poland, where abouts if you don't mind me asking? I'd PM you but you can't reply to PMs until you hit 50 posts. I'm in Małopolska myself, about an hour from Krakow. It's good to see some other people from Poland on BL. I'm actually only half Polish myself, but been living here for a few months now.
I'd very much like to hear your report psykap, and the reports of anyone else who's tried this.
Are you 100% sure that what you have is 2C-G? I'd start with a sub-milligram dose to be sure that you won't have an adverse reaction, then work your way up.
Let us know how it goes.
