Yeah..... This is a bit sketchy. Pharmaceuticals aren't just something that an amateur can make by following step by step instructions. Even something as simple as baking a cake requires some basic experience to know when things are going right or wrong.

Even maintaining the calibration on a CLR requires some background experience, let alone building and programming one all on your own. With your actual reactor being as small as a mason jar, it means the margin for error is going to be small as well.

This is neat for people with a background in chemistry, but I don't really see it as anything but dangerous for the general public. They also are fudging their math a bit to make things seem a lot cheaper. Reagents can be really cheap at bulk prices, but you have to spend the time looking for them, and they aren't equating the cost of a trained chemist making these medications.
