Recently, I’ve been testing with my pheros, and works very noticeably.
In my areal i have Ammo, TUTH, A314, IShine
I have budget of $100 spend to expand my adventure.
I am planning on buying IO, IH, or maybe IG…
i am experimenting this with social/my gf/friends.
any ideas?
You already have two none products and you are young so IO and IH would be a good choice.. In fact I think that you should buy them for first choice, because you need social pheromones also to make good mixes. 
Another one you could look into is CTTM it is mostly a 50/50 of IO and IH!
Than you could try something else instead of buying both.
I would get IG and use it with IS, for your age…
I’m your age and would recommend IG as well.
I haven’t tested out a314 that much, but I know that IG +IS works very well for me, and have seen others with similiar results.
