Actually I read in to this. It’s the same mones, but in different doses which greatly affect reactions: IJ has 12.5mcg/spray of androstenone
Ammo has 2.5mcg/spray of androstenone and a mix of androsterone and alphanol
IG is primarily made of androsterone around 15 mcg/spray
TUTH has 2.5 mcg/spray of anstrostenone (lower doses for holy sh*t attraction? Confuses me too! I guess this goes to show the more none you have, the more sex driven vibe you give off - like a jerk? Idk..lol)
It seems that the amount of -none greatly effects the reactions/outcomes on others. More info about separate molecules in the links below - brownie points for pheromojo and toiloftheday!
(info may have changed through time):

Taking it slow is not a bad thing my friend! One must strike at the peak of attraction, and mood through time - never too early, or never too late for optimal results. Whatever that means.. 
I think you should go for it man. I think IJ might work better for people 20+ (I have no idea). Just don’t blame me if you OD and get a bad reaction haha..i think with these heavy none products, it’s best to test them out first on people other than primary target as you don’t want to ruin anything you have with her..that is, if she doesn’t know you that well. Try finding your sweet spot first. Let us know how it goes if you decide to! No pressure..
