I've asked around a bit and it's probably just some junk indoles I can get rid of... [deleted]
The effects are certainly distinctly that of DPT and it is potent. It just looks like dehydrated clay, heh...
Edit: This is nastier than I thought. I now have 100mg DPT HCl in 5ml dH2O and am waiting for it to settle... There's quite a bit of tiny particulates at the bottom, and small tan grains cling to the sides and float on top. Should I even bother pre-filtering it (it's probably all junk plant matter anyway), or go straight to A/B/A? I'm unsure of the purity so I guess I'll be low-balling how much NaOH I use in the initial separation... 1/8 as much NaOH as DPT, I suppose, rather than the 1/7 I would use for DPT of known high purity... Or can I stick with 1/7 since I'll be separating with naptha anyway? In DMT A/B extractions, I've approximated the NaOH I've used before (though I do own a few milligram scales now) and ended up with pure product due to the naptha layer, so the ratio of NaOH to DPT isn't as significant here as it would be if I was only using water and NaOH, correct?
I've read through the DPT conversion subthread, but everyone in it was interested in obtaining smokable product rather than cleaning up nasty DPT HCl with an A/B and getting it into a proper injectable form. My setup won't allow for gassing HCl through the naptha-containing freebase--I'll have to use muriatic acid to convert the evaporated freebase back to salt form. Is this a problem given DPT freebase's relative instability?
Mods, at this point, feel free to move this into the DPT physical properties subthread...
