Mobius,
I've been reading a lot about Phenylethylamine (PEA), and the consensus seems to be that you can definitely focus on it, which would tend to put it more to in the adderall class.
And that's about the only consensus there is. Some people say it's euphoric, others say you hover right on the edge of euphoria in a sort of "kicking in" stage that lasts the whole time (usually compared to MDMA's initial physical rush), and others claim it's just a physical rush that borders on unpleasant.
As for how long it lasts, that is a topic of considerable disagreement as well. One reason for the variety of opinions is that people take it either alone or mixed with other drugs/"stacked" with other supplements.
Many people take it with an MAOI or a B selective MAOI (as it is monoamine oxidase-B that seems to metabolize phenylethylamine, giving it it's extremely short half-life). Selegliline (brand names: Eldepryl, Zelapar, Emsam) is the one I've most often seen referenced. In the United States, at least, MAOI's are prescription only, but not considered controlled substances.
Other people swear by taking it with the supplements Hordinine, Yohimbe, or both. These allegedly affect the half-life positively, but I know nothing about the chemistry involved or the actual effectiveness of these methods. The search engine will turn up a lot of talk about the combinations.
The people who take it alone also disagree on how to take it. Some take small doses for a brief rush and a lingering positive mood. Others take small doses and redose often. Still others take large doses (1 or more grams) and say that this extends the effective duration considerably. This could be due to the fact that there is only so much MAO-B produced in the body at once, and it takes some time to get through all the PEA. Another thought of mine is that it might be due to PEA's protein binding % in the bloodstream. If it has a medium to high protein binding affinity, the bound PEA could serve as a "reservoir,' coming unbound as the free PEA is metabolized. Unfortunately, since most discussions of PEA in scientific publications and online resources is about the endogenous PEA produced naturally in the brain, there is no protein binding information present. Anything produced in the brain avoids coming into contact with the bloodstream entirely, and so never has a chance to bond. But I;m getting a little sidetracked with speculation and someone more knowledgeable might be able to tell you with more certainty.
So there you go. My first shipment of 100 grams is in the mail and I should have it by medway through next week at the latest. If you want, or this thread is still a going concern, I can pop back in and tell you my personal results.
Sorry I couldn't speak from experience.
