This argument presumes that the entire many-billion and maybe even multiple-trillion dollar global ad industry is ALL based on complete, ineffective nonsense.
Strangers things have happened than money being thrown at bullshit.
Opill is known as a “mini pill” because it contains only one hormone, progestin, in contrast to “combination” pills, which contain both progestin and estrogen. A company that makes a combination pill, Cadence Health, has also been in discussions with the F.D.A. about applying for over-the-counter status.
So good luck DIYing a transition with these. Progesterone will develop milk ducts but it won't make breasts grow.
