I'd highly recommend the Netflix documentary Icarus. The filmmaker starts out trying to more or less replicate the doping routine of Lance Armstrong while competing in amateur cycling.
I don't want to give anything away, but the documentary takes an incredible turn once the filmmaker meets Dr. Grigory Rodchenkov — who ran the Russian anti-doping lab prior to Russia's ban from the Rio Olympics.
