I really want to get instant fem magic because it says it readily builds comfort which is a big ideal in the mystery method, but most of the reading i do suggests openess. If I am going to be going around approaching tons and tons of college girls, which of these two would be best?
Personally that depends on the setting and circumstances.
for a Club, restaurant or public atmosphere, I would say Ammo.
for Sales, canvasing or signature grabbing- IH
Sports or Cheerleading- IFM!
if you are slightly shy, IO.
for general classes or daily wear IO or IH.
Do you have a financial constraint that means you have to get either one or the other right now? If so I’d recommend the Instant Openness - just because the effects and self effects seem to have more oomph to me, for the approaching thing.
If not, there’s no reason why they shouldn’t work together… -nols and Androstadienone won’t interfere with each other’s effects.
Even if it is a cash constraint, a $15 gift certificate from the Welcome forum is a free togo of something to play with.
So getting 2-3 togo bottles is pretty cheap. (less than 1 full bottle) (unless footing the bill for overseas shipping, in which case ordering 3-4 full bottles would be recommended)
The trouble is you could get hooked on all the purchased products and you will find your self scrounging for money to buy full bottles of all of them. 
You seem to be very knowledgable, usually you find guys who think they can use Turn up the heat to arouse a girl enough into having sex with em after meeting them in 5 minutes… Id use openness over IFM but thats only preferences, openess leads to more communication, which is more helpful for me…
You really need to try both man. IO does not seem to work for me, even after extensive testing. Going to try IFM next.
Openness will work on just about anyone at any time. IFM works best on females, can be a “downer” to males, and is best used when the girls are bitchy or otherwise on edge. I see it more as a “comfort” pheromone, and it may not have an “immediate” effect. They may think of you in good terms when you meet later however.
If you can’t swing both, go for IOpenness first. Just remember not all all pheromones work on/for all people all the time.
My opinions.
I don’t know shit about reading friggen mystery novels, but I do know something about Instant Female Magic and Instant Openness. Both are great products but totally different tools.
Instant Openness is a general purpose product–mainly alpha Androstenol–and enhances verbal communication. Yeah, ah hoe lotta tongue wanglin’ ‘n cluckin’. In my book, it’s the most important and essential pheromone for life. Period. It says “talk to me as I’m a healthy and friendly dude.” Business or pleasure–a-Androstenol gets it done.
Instant Female Magic–mostly A-1–in my experience is a one trick pony albeit the among the best and most consistent at its single duty. In most circumstances I found it does little or nothing. Zippo. However when a woman is suffering PMS or other hormone related moodiness or bitchiness, Instant Female Magic wipes that shit off her face and replaces it with a smile 'n a giggle. Works every damn time (assuming you’re not an asshole & being nice). Amazing.
Unless she’s on the rag, I wouldn’t bother with Instant Female Magic to create “comfort.” A waste of expensive product. Use your damn sweet personality coupled with nols & maybe a dab 'o Instant Gentleman for that.
Damn…didn’t know that. Just paid for a bottle if IH double strength. I hope that was worth it.
