Has anyone tried this mix? I just ordered IO and IH, and would it be better to use TuTH or ammo? 
Definitely ammo, I use it all the time. Though with both IO and IH TUTH would work quite well- I only have IH but IH+TUTH is a pretty good combo.
I find that TUTH is a little too pronounced for school unless I’m really trying to push things forward- I usually wear ammo and some A1
Keep in mind that your socials are going to get some reactions where people can talk, but in HS you are discouraged from speaking. The teachers want you to be quiet so they can teach.
Where as IO and IH are designed to get people to open up and speak more freely and openly it still wont change someones free will. If you would get in trouble for speaking in class, then most likely you wouldn’t talk. You will see more fidgeting and other body languages indicating a sense that your peers want to talk, but aren’t allowed to so to supplement they will do other things. All about motor movements.
Ammo would be a much better choice as its well buffered and steers the interaction into “you” being the sexy guy, rather than the TUTH vibe of “sex”. There’s a big difference in being a sexy guy than a sexual guy. Ammo still wont make anyone break free-will and be careful of how much you use (one spray). It sure is fun though watching those girls squirm in their chairs thinking of all the ways you want to corrupt them.
Key to it all is have fun
I just finished up my last day of HS today (woop woop!) and I found that Ammo worked great in the HS environment. TUTH comes off a little too strong. Like Steve said, you just need to make sure not to OD on it. Two sprays is my sweet spot
