That's a great question. In this case, the drugs are small-molecules (https://en.wikipedia.org/wiki/Ledipasvir/sofosbuvir https://en.wikipedia.org/wiki/Ledipasvir/sofosbuvir) and they're complicated ones at that. So trying to make that at home would be impractical. But you're on to something I've been personally interested in for a while. You can make proteins at home in cells, but to get them pure enough for injection is near impossible without expensive manufacturing equipment and testing equipment. I think the real win is going to be using mRNA coding for the protein of interest formulated in lipid nanoparticles. This type of idea would be easier to make sterile and have basically no risk of endotoxin/virus issues recombinant proteins have. I give it 10 years before garage biohackers start really getting this idea to work.
