7-Acetoxy mitragynine

[bewilderment]

Does anyone know anything about this compound? I've seen it offered as an analogue of mitragynine, but there's no other information about what it is or effects on the site. I would chalk it up to some kind of misprint of 7-Hydroxy mitragynine except that's mentioned on the site as well so I don't think it's a mix-up. I did a search for it on google and on erowid and came up with nothing. Also, there's a tincture which contains 25mg 7-hydroxy mitragynine/75mg mitragynine going around. From what I've read 7-hydroxymitragynine is somewhere around 17x more potent than morphine so I'm curious as to what the effects of this tincture would be. Has anyone tried it or know anyone who has?
