I just got my P74 in the mail today and haven’t yet used it at all, but I ordered it because I liked the “cool chick” feel I got with Mx274, which is based on P74. Before I even had read up on the P74 (or knew that MX274 was based on it) , I wrote about how I felt like a laid-back, mellow…just cool girl with the Mx274. 
The other members who have been here a while will probably advise you to try it for yourself and take note of any effects before you fill your head with how the product is supposed to work (especially putatives and experimentals). I know that’s hard, especially as a newbie…
Anyway, here is my favorite thread on P74. I was excited reading the part about the “cool” effect because it described how I felt with it. Use the search to find out more info.
