Thanks! 
Also, how would you recommend I go about testing the products I buy? Where should I first go to test them? How long do the products last? What behaviour should I look for to gauge the reactions (or lack thereof) that I get?
That’s the pleasure of testing. You’ll have enough sprays in each bottles to test them in different settings and find your best dose for each. You can also experiment different application points. Remember to test the products solo first before attempting mixes.
TUTH: This one is a sexual and is better for intimacy or the bedroom.
MX297: This works better in party settings / clubs / bars.
The others can pretty much be used in any settings.
