Not sure why you keep going on about PCT zone. The difference with Indian pharma is that there is quite a lot of testing out there on Indian Pharma products. The vendor selling Indian pharma products doesn't produce them, they just sell them. So a test of a product from that manufacturer is good for all vendors. When you're dealing with a Chinese source that is making their own stuff, they need to test every batch. There's a big difference.
I'm not letting the vendors for Indian Pharma off the hook as I still want to see testing from them. Also, when you're dealing with UGL Chinese manufacturer, it is pretty different than dealing with a large scale Indian Pharma manufacturer. If you've seen enough Indian Pharma tests you can basically figure out which companies are good to go because of their consistency over years. Of course we should continue the test over time, but certain Indian pharma companies have been consistently good for a long time. With a Chinese ugl vendor it varies wildly and batch to batch can very wildly. Consistency and quality control Is significantly better with well-established Indian Pharma manufacturers. Batch to batch can vary wildly and often does with many chinese ugl producers. Consistency and quality control is WAY more variable.
