Well it seems like the authors of this older thread may not visit the nexus much anymore.
Thankfully I seem to have had some success on my own.
I have no idea the chemistry behind it, it seems that for some reason the magnesium granules taking 8+ hours to react with the vinegar caused some sort of reaction that made ammonia basing precipitate a dark brown goo.
I had the idea to flatten the granules and increase their surface area significantly, making the reaction similar to the magnesium ribbon one that many have done successfully.
I did a dual test on both flattened granules and no harmaline (just vinegar). After a little over 1 hour, the little magnesium flattened disks dissapeared and basing with ammonia caused no precipitation.
I then did a 200mg harmaline test run and after 1.5 hours I got a very similar precipitate as was floating above the brown gunk from my last post, but NO BROWN GUNK! When I tested the UV, it seemed very green.... THEN I RINSED IT, and it was a faint purplish blue!
I tested it sublingually, somewhere around 12-20mg and the effects are very significant. I sometimes have placebo headspace changes for up to 30-40 minutes with inactive things, so I was very careful to be critical if that was happening, but it's been 3 hours and the effects are surely way beyond placebo. I didn't actually try harmaline sublingually before to compare, but precipitating it looks nothing like the sparkly glitter harmaline, it is all fluffy and globby. The effects are quite energizing and while I don't ever get "euphoria" from psychedelics, I do feel a typical serotonin abundance feeling. I hope that it is not just conformation bias, but continues with further tests.
The above picture is from a 1.27g test I did, replicating the apearent success of the 200mg one. I've read with zinc it is typically 75% yield, I got 61% which is okay given the coffee filters likely absorbed a not unsignificant portion of liquid and trap the fine powder within the fibers.
I am very nervous to manske this precious THH, but appearently the freebase is somewhat unstable compared to the THH HCl. So I have the convesion of the other 7ish grams of harmaline and the manske to work on in the near future.
