^True, he did find quite a bit of value in DOEF. One reservation I have about DOF (mulling over what I said before), however, is the fact that 2,5-dimethoxy-amphetamine (DMA) is pretty much inactive (aside: has anyone ever tried this one to confirm its lack of specialness?) and a fluoro-moiety on an aromatic ring isn't all that different than a hydrogen. On a naked amphetamine, that is a good thing. Take for example, 4-fluoro-amphetamine, a compound that I have always heard stellar things about but never had the pleasure of trying. Clearly, it is not like its nefarious and evil brethren, the serotonergic neurotoxins pCA, pBA and pIA. But on a 2,4,5-psychedelic, a decidedly less-than-naked amphetamine, don't we need something on the 4-position with a little oomph? The claim in PiHKAL is that DOF would be around an order of magnitude weaker than a heavy-hitter like DOI. If that is true, then it should be spectacular. If, on the other hand, is it like 2,5-DMA, well...well then I have no idea what to expect.
