Yup - Both the same. MX297 is in Akuto whilst MX390 is in F21 (Ammo). Not tried the stealth versions yet.
Instant Rockstar or Smooth Operator suits it best. both has been already suggested by Pago and Extraball 
Or Call it Mr. Popular
Its best suited for those who have social anxiety. All those beta and alpha shit comes later.. when u are stuck in the corner in a party and too anxious to have fun and interact with people, or just be friendly and befriend the pretty chick u r interested in, all that beta alpha crap wont help. they click in only once you have the social confidence.. MX297 gives exactly that..
Nad King? Big Kahuna? Papi?
Can you please elaborate a bit more on what you experience in the day or two after using 297? Do you feel anxious or depressed?
Wife calls it “I want to rip your pants off”
Is MX279 and Ammo a good mix and what ratio of them each ?
