I have sold from every production run Sun (a bit less from the other manufacturers) has had in the last 3 years and have zero reason to believe in bad batches.

That said the complexities of medicine make these claims impossible to prove or disprove on their own merits.

I would welcome anyone that wants to develop a real testing solution to this. It would help me sell more and I'd pitch in to funding it, I'm sure most of the other sellers would too, we don't gain anything with questionable product.

Most of the allegations regarding pharmaceuticals from India being inferior in quality is a load of crap. Big Pharma sources a lot of precursors there. For cost cutting a lot of work was outsourced to India and the knowledge gathered was later used in new founded companies that made generics, that ironically has become a serious competitor for Big Pharma and a certain threat to their business model.

As precursors, knowledge, production process and so forth is identical to that of Big Pharma, I don't see why there would be any difference in quality. I'm not talking about counterfeit pills, they do exist, but any vendor selling that is out of business soon.

Testing that is not that difficult. A Marquis reagent is a good indicator to isolate what is in a pill sold as modafinil. The shade of color visually indicates the strength.

That does not tell you how much mg you have in a pill, but does allow you to test a so called 'US/EU' Premium brand. Basically there should be little or no difference.

Word, someone should tell this to the fuckwits on r/afinil.
