I would recommend going for 2-Oxo-PCE instead for various reasons. One of them being that these diphenylethylamines that Ephenidine belongs to have not been as thoroughly researched as arylcyclohexylamines that 2-Oxo-PCE belongs to. I am a huge fan of both, but 2-Oxo-PCE wins in every aspect. They do share a lot of traits, so you won't get a totally different experience, compared to say ingesting 3-MeO-PCP.
Another reason should be financial considerations. 2-Oxo-PCE is much stronger mg by mg. However if you are in the UK the latter may fall under the dissociative blanket ban while ephenidine may not. I have no idea to be honest.
Oh and there is really no reason to apologize to anyone imho eventhough good manners are always a pleasant sight.

I could see that most people would assume gastrointestinal bleeding is internal bleeding which is part of why I felt the need to mention it is not. An eye opener to me was when I first heard the notion, that the gastrointestinal lumen is really not inside the body but keeping the inside separate from the outside it was an eye-opener for me. We are basically a long tube. :D
