I was expecting a couple more pills in the mail from people who posted in this thread, and hoping to test them side-by-side. In the meantime, I'll just post the results so far. Here is the test result pic. Note that Mandelin test was not used- only Mecke, Marquis, and Simon A&B (in that order). Compare that to the table of common substances.

The pills tested are shown to the left of the test results. The first is Nuvigil (armodafinil) from Cephalon. The second two are pills provided by someone in this thread- the second one down came in a pure foil package, and the final one came in foil+plastic. Both are seemingly Modalert 200.

At first glance, it seems like all would be classified as meth/amphetamine. However, the test results end up far too red, in this case- I have tested meth/amphetamine several times and it will always stay a solid orangey color, never deep red like these. Also, Mecke shows that there is no amphetamine in these samples.

So, ultimately, all three test identical- there was no discernable difference in any of the tests. I will follow up by taking the pills instead of my typical Nuvigil, and give a subjective report.

Also, a friend has pointed something out. In my last post, I said that amphetamines/speed and modafinil/armodafinil feel "VERY different." While there are many clear differences to me, having taken both (ex: speed/amp will always give euphoria, even in extreme overdose, while ar/modafinil will not), I can very much understand how too much ar/modafinil would feel like being drugged with speed- your heart feels like it is bursting through its chest, there is extreme anxiety and rising panic, and the world just generally feels awful (I got this effect from taking a full 250mg armodafinil after the gym- normally, I break up my pill in two pieces and take one first thing in the morning and one before lunch).
