The FDA has rather strict quality control standards so my guess is these pharmacies have not gone through the process to be fully licensed. And another thing:
But worse than that, he believes that the single biggest reason neither the FDA nor the pharmaceutical industry has put much effort into testing, is that they are worried that such tests may show that the drugs being sold by many so-called rogue pharmacies are by and large chemically indistinguishable from those sold by approved pharmacies.
Yes...after the quality control of toys, toothpaste, dog food, and drywall from China, we're sure we can trust their quality with our pharmaceuticals.
Yeah, you know, they are "by and large" indistinguishable from the real ones. I mean, what's a few PPM of arsenic, or cyanide, or lead? The rest of the drug is still there, and that's what you ordered. You wouldn't send a gourmet steak back just because the cook brushed a little olive oil and salt on it, when it was listed on the menu as just a steak? So why are we rejecting these drugs?
