I got IO, IS, IG, and Ammo. What is a good combination for women to notice me and be comfortable to talk?
YOU.
That is the magic.
In all seriousness, IS and IO, a shot of Ammo depending on your age would be good as well 
Ok I just turned 20 so how many shots of ammo
You really do need to do your own Sweet Spot testing:
And at your age, seriously consider using just the socials instead and save the Ammo for a date/night out situation. IS, IO and IG are all great at provoking interest in girls around your age and TBH, it is better you get the hang of each phero individually before you start maxing them.
I’ve used ammo with the IO before and I got a successful hit.
Try each one on its own then, so you know what caused it - IO can be great on its own as a guy your age is likely producing a good bit of none already - don’t add what you don’t need.
Just one spray? so like 1 spray of IG tomorrow
Yes - One spray is as good a place to start as any.
Less is very often more with pheros, even socials. Although I reckon you could safely start with 2 sprays of IS/IO as they don’t have none OD or status issues.
yeah I’ve received hits with IO and IS. The newest one that I never tried is IG
IG is one you should try on its own first - Then you will know how to dose and steer it in line with your personality via the other pheros. If you need to.
What’s the benefit of IG. I know it supposed to make the guy look caring and alpha male authority
Yeah - smooth, suave status but very social without the heavy vibe of A314 - which can be a bit too serious and upstanding for younger women. You don’t want to come-off like their dad/headmaster!
Another noted quality of IG is that its rone content goes down very well with asian women. If that’s your thing?
Glad to know on that lol. What would be a good mix for latinas?
Try looking up the many latina threads - There is a lot of good advice here already.
TBH, latinas can be the exception to the none/age rule. It is often reported that across the age ranges, they can be more responsive to a higher amount of none than their european contemporaries. Personal experience of working with quite a few latinas and having an ex with hispanic roots also bears this out - She was a right none-hog and boy, was it fun! 
I have IG, IS, and Ammo. I’ve tried these three as a combo before I tested my sweet spot and I seem to get hits from a girl I have been seeing. As someone said at your age be careful of Ammo, too much of that can be a bad thing. Luckily you have IO, IG, and IS that can help you from ODing
yeah i tried IG today. 1 spray and I got no hits at all.
two sprays tomorrow then - and so-on till you see response and it tailing-off again. Then you know your sweet spot.
IG’s a strange one for me,
Either ill get walked all over and people give me strange looks
or
I come off as sophisticated, confident and … somethingelse that i cant quite pinpoint
Well so far, I’m not a fan of it. I didn’t see any looks, I didn’t see any interests. Nothing.
Bro its a tool..
Just like Gel, Clothing..
If your not rocking it, it aint gonna do shit for ya.. nothing will bro you cant just stand there and expect the ladies to swarm you without any work on your part.. start approaching bro and youll find it works wonders
