I would describe the taste when smoked as 'chemicalish', but not too retched.
I think 5mg is too low a dose for this stuff, but not having snorted it I couldn't say what a good dose would be.
I find about 20 up to 50mg (perhaps even more, but I'm pretty much a lightweight) a decent dose for smoking though.
Some more observations... pretty short acting, maybe 45 min for back to baseline... but that's a plus as far as I'm concerned.
For some reason, I find this stuff to alter time perception big time, especially the first 5 - 10 min which seems like 20 min to a half hour to me. Really weird and consistent in this regard.
I also find it 'opens me up' to the 'other place', kind of like how salvia does... entities and weird machinations of the mind occur, but there is no paranoia and a pervasive calm sets in.
I believe win fx will turn out to be strongly anti inflammatory, just my sense of it. It does give a nice mellow analgesic numbness that is noticeable to me.
One thing it does well is provide the sense of release and relief that smoking cannabis gives, yet there is a bit of stimulation as well. My woman and I both agree that sex is enhanced at every level with winfx... tactile, mental, pleasure, libido, all these aspects of sexual enjoyment seem increased. Dare I call it an aphrodisiac? Well, if not that, it does enhance the experience (but lots of drugs do, so it might be a moot point).
