Daraxonrasib, Afatinib, and SD36 are molecules that can already be purchased in bulk, and what's the worst that can happen?
Our society's morbid, irrational fear of quack medicine causes orders of magnitude more deaths through therapeutic neglect than it prevents through safety screening. "Better 10,000 die of cancer than 1 person die of fraud/waste/mismanagement or even in failed experiments performed in good faith."
