Hey I was wondering what a good sweet spot for a 17 year old male using just ammunition. This in a high school, with girls around 16-18. Also would it work on teachers, around the age of 28 and above, just curious? Also the first time using ammo in school setting I found that the guys were really chill instead of girl sending ioi’s and showing attractiveness. It made me a little jealous because my friends were getting the girls actually and the girls that I usually talk to would like talking to the other guys. I used 1 spray of ammo on my neck, 30 minutes before entering school. I’m also living in Canada where the weather right now is just below 0 atm. I was wondering if someone could also help with that.
The only way to find your sweet spot is to test a range of doses and see what works for you individually.
Starting with one spray is good, if that’s no good, up it to two and so-on. At seventeen you won’t likely have to go too high. Also look to taking the pheros out of school with them. You may find that girls are more likely to act on any attraction in a more relaxed environment, away from the all pervading-eyes of their peers! 
Diffusion tails-off rapdly as the temperature approaches freezing. There isn’t a lot you can do about that other than make the best use of warmer indoor spaces, cars etc - and this can be good because the warmer, more humid environments indoors in winter do actually help your diffusion greatly.
Yes, it may work on teachers but in ther late 20s, they may well be tuned to a higher dose that could be incongruent with your age - also be aware that no competent professional educator would let themselves act directly on any feelings of attraction for a pupil. That could be a serious, career-ending kind-of risk to take!
However it may mean they get a little sweet on you and help you/show favouritisim in other ways - which could be useful.
Thanks for that and usually i got nothing out of ammunition but today i messed up spraying. only half of it got on my neck because i didn’t see the hole clearly and i noticed more attention. Girls that would stay silent talk more and 1 girl was just right beside me and couldn’t stay away from me. However the 1 girl who always talked loud was a little quiet so idk what happened there.
You can get a reasonable half-spray with a bit of careful finger-control on the sprayer and on a young guy, that is a viable dose.
If she was used to talking freely around you without pheros, then yes she might be taken-aback by her feelings when first exposed to you with them. Stick with-it, she should adjust to liking them pretty soon. 
Reminds me of a joke…
I like my whisky as I like my women - 12 years old and mixed with coke.
OK, a bad joke.
Definitely not a joke for all public, but it’s the first time I hear it. Thanks. Lol.
