You said you didn’t notice people behaving any different with the IS. How many sprays did you use? Have you done any sweet spot testing? Sweet spot testing is important for you to find your optimum number of sprays for the best effect. Sweet spot being a number of sprays** not** a location on your body. Locations can be anywhere; for the socials, I like to put them on my wrists and the back of my hands. So if you talk with your hands (I do) you wave the mones in people’s general direction 
. Personally, I like to keep IH on my head, or back of my neck. I’ve already done the thing where the effect has people telling me all sorts of stuff that maybe the shouldn’t be saying out loud - and I wanted to reciprocate!!! 
Had to keep a tight lid on that! If you read the journals of experienced testers, they will specify at the beginning of the post what and where they are applying mones.
When testing, try one spray to see if there’s any reactions, then 2 the next day and so on. Testing one product at a time - so you know what these do for you, the people around you and the best dose with each product. For instance: I max out on IS (apparently this is unusual) at 3 sprays. IO, on the other hand, I’m up to four sprays and still getting amazing effects. Read this, it’s not long and explains in proper detail what it is you’re needing to do:
How to find your sweet spot...
So, what I think is you haven’t done any real testing just yet and haven’t found your sweet spot for IS. Do that and regale us with your adventures . . . 
Hope this is the help you wanted. Looking forward to reading your posts!
