"At the pharmacy, a pair of single use Mylan epipens can cost over $600 and the company’s generic version costs $300 per pair, but an ongoing shortage means you probably can’t find them, even if you can afford them. In response, Four Thieves published the instructions for a DIY epipen online that can be made for $30 in off-the-shelf parts and reloaded for $3. Shkreli drove the price of the lifesaving HIV medicine Daraprim sells up to $750 per pill. So Four Thieves developed an open source portable chemistry lab that allows anyone to manufacture their own Daraprim for just 25 cents apiece."
