P123 can be very subtle if the right situation doesn’t come up - good reporting - I’m sure you will see results.
By the way - my most consistent results with P123 were in the 37.5 mcg range.
Make sure you talk to people - actually… try to talk in class (answer questions and that sort) -> If P123 has the effects that I think it has, it will be difficult to see anything simply observing other people’s reactions passively
