I'm confused. Are you saying that every time you receive a package of medications from India, you send a sample off to for spectrometry?

That seems extremely arduous.

The point is that you don't trust this specific supply chain/manufacturer, which is part of the approval process.

"India/China" is not some monolithic entity that is either good or bad, there are some manufacturers that you can trust, and some you cannot.

Quality control in drug manufacturing is what ensures that every single pill has the correct dose, and not some random batch accidentally having 100x the active drug you need - or 0.01%.
