Question about plasma brain of youth

[Johnny]

I plan to buy “How smart are stem cells?”. I am not sure what the benefits of plasma brain of youth. Can someone explain it to me or provide a source to read? (Thank you in advance.)

Hi, Johnny!
Check here:

The Plasma Brain of Youth (Hidden Bonus Item)

For anyone that doesn’t understand, the Smart Stem Cells field has another addition to it called The Plasma Brain of Youth that was just added in by Dream as a hidden bonus. You can get this brain field by buying the Smart Stem Cells field as they come together. The Description for the Plasma Brain has been written in Bold for everyone to see.
