Ask HN: Any first hand or witness accounts of clandestine chemistry?

The term might be kind of interesting, but basically non-traditional lab work. I got the term from the steroid industry. Game of Shadows is a good primer. Romanowski’s autobiography (4 rings, no HOF ever) another good one. Basically I’m curious about experience with medical self-supply based on existing and also well dated techniques. Really mostly a blood component to extract and/or replicate been done for decades. It worked for BALCO. Old German steroid recipe. I also consider going to Nepal with files in hand and getting some quotes, my market personally can scale. Many thanks in advance.
