On a side note, as I see that you also experimented with NMT which is a tryptamine with poor oral bioavailability (according Shulgin, #50 in Tihkal).
Now I do not exactly know the laws around tryptamines, but did you researched the possibility of finding a legal and natural tryptamine with good oral bioavailability and use it as a stimulant? Do you know about Dr. James Fadiman’s work on micro dosing psychedelics? It seems that a micro dose have a good stimulant with anti-depressive properties. Now, I understand that you cannot use what Fadiman experimented with, but I suppose, that there may be a similar compound in structure and properties as of those that are already scheduled?
EDIT: Hmmm, I probably was too quick with assuming that NMT is N-Methyltryptamine, while you probably meant N-Methyltyramine? However, the question still stands, since tickling the serotonergic receptors seems to produce very noticeable stimulatory effects.
