Geez I almost always have the opposite problem. Except for certain psychedelics I have always meant to try and never have yet due to being intimidated, despite having all of them nicely labeled in vials in my closet. Particularly, 5-MeO-DMT, and DPT. I also need to try my DOB and TMA-2, but those aren't due to nervousness, just the fact that it's hard to find time to be tripping for 24+ hours.
