I understand p74 but isn’t the p93 nicknamed “caucasian magic” https://pheromonetalk.com/t/p93-caucasian-attractant-or-the-first-known-racist-pheromone/12830 ? I couldn’t find much on p93. Can you explain the effects and this whole nickname thing?

As usual there are differing opinions as seen here
