If it helps, I just ordered P79, TAC, and TAA.
TAA is the main ingredient in IS (with buffers), but is shown to be more effective. I’m going to experiment and compare TAA (12.5 mcg/spr) with IS (2x/spr). I’ve had good effects with IS 2x, so I think this will be interesting!
TAC, as GHOST mentioned is a very comforting and easing molecule. It should help put both guys and girls at ease and more friendly. I feel this is a great buffer for any mone-type product like Ammo (probably in lower doses).
P79 seems popular, yet confusing. It’s an intensifier and can have both good and bad effects. If someone likes you, then you will amplify that, but if someone hates you, then oh boy… I think this will go well with your P83 and possibly Ammo. People seem to get mixed results with this, but based on Scottie2Hottie’s report, I am getting it dammit!!
For my next order, I will be trying out MX297 and MX412/MX413.
MX297 is supposed to be “the life of the party” mix and seems to work well for any type of social setting. I have a few female friends that are pretty wild when they’re together - kind of the life of the party. I think with this mix, I could make that even crazier 
MX412/MX413 is supposed to have similar effect as A-1, or androstadinone, but without the depressive effect on men. It should put women in a good-feeling and calming state.
Hope that helps a little. Just curious, how has P75 treated you? I’m thinking of adding that to my next order too, but not sure yet.
