As mentioned here, we are offering free testing of Phalaris (and other) plants/extracts
Ive been updating the first post in this thread with published amounts of tryptamines and other compounds in some Phalaris.
As for P. brachystachys, ive been having a hard time finding any concrete numbers. The Festi and Samorini article linked in that first post says that exclusively DMT has been detected as far as tryptamines go, in brachystachys, but no quantitation has been done, and the HPLc method doesnt seem to have included beta carbolines, gramine or tyramine analogues in the search. Id be happy to help publishing a first quantitation of alkaloids in this species.
Lastly, I just want to urge people to be extremely careful with Phalaris. We have some people experimenting with these extracts without doing any sort of analytical testing, and talking about listening to spirits and to how one feels subjectively as the sole means of judging whether the extract is safe or not. Each one to their own of course but IMO that is dangerous because we humans can be mistaken, and damage doesnt have to be noticeable subjectively to be problematic (you can even find cases of people being shot or having stuff go through their brain or large tumors and not even noticing)
Some of the compounds found in Phalaris have very little to no pharmacological studies, and others such as tyramine analogues are known to be cardioactive, increase blood pressure etc. Plus we are talking about combination of these alkaloids which makes it even more of a concern.
Be safe everybody, and let me know if you want things tested.
