To clarify, I submitted the sample. The note is in EcstasyData's report, because I contacted the vendor about reagent results for 2C-B-FLY not matching the reference samples. The vendor was forthcoming, explaining that the 2C-B-FLY, 2C-EF, and several other rare unscheduled phenethylamines that had been offering were not new syntheses. They said that they were in storage from 2009-2011, pre-WebTryp. I have no idea of evaluating the accuracy of that.
I do know that based on reagent results, the vendor's 2C-B-FLY was something else. It was submitted for analysis, but the results aren't in yet.
Based on the fact that one of the PEAs was not as described and there were no reagent references for 2C-EF to confirm its identity, I submitted it for analysis too. My sample contained no 2C-EF, and will need to be disposed of later today, as I don't want the legal liability. I let the vendor know what the results were late last night and hope to hear back soon.
I'm sure the experiences were pretty magical - those are some wonderful materials, and a combination might be pretty lovely. However, because insufflating 2C-T-7 has killed people (and people have been snorting this stuff,) I wanted to make sure people knew what they might be taking. The 2C-x compounds have a pretty good safety record, and I could see people pushing the dose or combining with non-combo drugs like MDMA assuming that it would be safe, too. It also might explain the erratic dosages for this, with some people getting no effects at oral doses of 10-20mg while others got effects from doses as low as 3mg, suggesting there's the possibility of potentiation or uneven distribution. 2C-T-2 is pretty potent, 2C-C is not at all potent, and 2C-T-7 is really, really erratic in its oral dose-response.
So, we have a Small & Handy thread here and tons of posts on other web forums about a drug that likely came from one place and (unless there was a single vendor mix-up) was not the drug we thought it was. That means that most if not all of the info we have here doesn't pertain to 2C-EF at all, but to a combination of other drugs and isn't of much use to us or anyone thinking about making it in the future.
The most important takeaway here for me, though, is that there are now pictures of the reagent test results for the compound that was shipped and labeled (quite possibly unbeknownst to the vendor) as 2C-EF. If you have reagents, you can likely now determine what you've been taking and reporting on was an entirely different mix of drugs. This presumes that this was a whole batch of something sold as 2C-EF. If it was mixed up differently each time, which seems less likely and I hope was not the case, then all bets are off until we get an actual GC/MS confirmed sample of 2C-EF to compare against.
