Uhm, I have learned numerous molecular biology courses in the past few years and still keep up with the knowledge by reading articles about the developments.

Let's just say, you assuming that "top experts and a lot of money" is a sufficient fact in which you base your opinion on in regards to this topic is not enough. The guy above proposed that modifying molecules chemically can produce a drug with the same function but won't be detected in tests is something far fetched in my opinion and I base it on scientific facts.

I don't want to delve too much into this. But say changing a molecule even slightly (I'm talking about a single molecule here) can cause chaos in a physiological sense. Especially when the new product wouldn't be tasted sufficiently even if you pour all the money in the world, you can't get it legally approved and have it tested meticulously. Let me give you an example, in Israel there was a crisis about 2 decades ago in regards to a baby formula produced by a German company called "Remedia". The company has top shelf laboratories and has a plethora of resources. When it decided to skim a bit to reduce costs and "fuck around" with the formula, vitamin B1 - Thiamine wasn't included in the formula properly and that led to neurological damages in numerous babies (I can give an explanation as to why if you really want).

I'm just saying, it's really far fetched that a person with a degree worth his salt and has the appropriate knowledge would go around and fuck with pharma drugs for money.
