How long did you experiment with them?
As I found out it can take a looooong time till you really get a acceptable skill to recognize REAL hits. Often people think “oh she gave me a smile” this must be a hit, of cource could be but also without mones she would have given you this smile.
I did not have such an awesome playground as high school, so it was much harder for me to learn due to few chances to use the mones.
But although when you have many chances at frequent intervals, it still can and most times takes a lot of time to learn this! The mones enhance your behavior. So if you use IO you must be open and if you use A314 you must behave dominant to get the maximum out if it. You cannot expect to have blatant hits especially at high school.
So be patient, look at the stickies in the forums like: How to Tell a Woman is Interested In You -- The Master "Indicators of Interest List"
However what works for the others must not work for you. You have to experiment with the dosage. Find a dosage with the certain product or mix you can best be congruent to.
I read so often that it is 90% you and 10% the mones but I think different. It is always 100% you and the mones can amplify it to 110%, 150% or even more 
It just belongs to you what you make out of it.
So read carefully the stickies and tips from others howto make the most out of your mones and you WILL succeed I swear.
And as I told before be patient, every skill just is not a present, you have to learn and earn it
