FWIW, Snopes classifies this as "Unproven"

Well, it works still just fine
@SmudgeTheInsultCat While quite plausible, with the possibility that such experiments actually were conducted, the only source to this claim is this very flimsy piece of paper with the almost entirely blueish scribbled underscored text, or references to this very photograph of piece of paper.
‼️ So please, take it for what it is: a NOT confirmed reference to a plausible but unconfirmed myth! ‼️
@SmudgeTheInsultCat P.S.: The worst part of this, what I am calling urban legend, is the bold mention of those absolutely INFAMOUS "two months or less".
The absolute absence of confirmation of this part of the claim is IMNSHO* totally not acceptable and should make stop people to spread this rumour.
