Tested
Ammo x1: nothing to report about really
Ammo x2: very confident feeling! Not caring about possibly not looking best at that time…
Ammo x1 Mx297 x1 : a few social hits
Ammo x2 Mx297 x1 : a few social hits
Ammo x1 Instant Openness x3: I felt the IO 's effect literally! When I met girls on the street they were chatty as fudge. No IOI though before approach.
Ammo x2 Instant Openness x3: same as above
Ammo x2 Instant Gentleman x1: only self effects. No IOI , but I got a “I got dis” feeling for half of the day after application.Very tired out after the effect.
Summer Ammo x 2 Instant Shine x 2: Ah that was a wonderful relaxed day. It was stressful Winter but indeed feeling like Summer, kinda. I was enjoying myself and forgot about my worries. Less than a hand full of IOI over 3 weeks.
Summer Ammo x 2 Instant Shine x 1: same as above
Summer Ammo x 1 Instant Gentleman x 1: nice confidence boast! I got some social hits around mates. Often just wanting to be around me. 
IG x 1 : None
IG x 2 : self effects, respect social hits.
IG x 3 : good, but worse than IG x 2.
Mx297 x1 : subtle social hits
Mx297 x2 : social hits
Mx297 x3 : headache, less hits than with Mx297 x2
No obvious sexual hits, hardly any IOI from the mixes above. Others seem to have it so easy ._.
