Back of the head is great for Instant Honesty, especially if you don’t want to be spilling your beans.

I can clear this up for ya. It’s neither. MX274 = TAA + P74 + 4/5 other pheromones. MX335 is the grapefruit scented version of MX135. MX235 is the cookie version of MX135. So, MX135/235/335 are all the same TAH heavy mix of 56 different pheromones. 
MX134 is TAL heavy and better know as the women’s A314. 
MX108/109 aren’t available. They’re long gone and were part of the Drive Him Crazy series. MX109 is the “woody maker”…uh huh. 
We’d all like to get our…hands…on that one.

O, this tread is interesting.
So, I recently purchased To-Go of Instant Shine, and used it before going to class, library and such. This was more of a self affect test as I was trying to monitor myself rather than others around me.
First half hour was ok, no noticable change. Then all when I went to sit down to study, I got agitated because I was thristy. I mean like agitation felt when you are extremely thristy. So, I got up, got a bottle of water, drank a small bit, and found out that I was not all that thristy. Weird, still agitated.
The agitation is more of a restless type of agitate where you can not stop moving or something like that. After about 3 hours of this, I decided to shower to wash everything off. Now I can sit down to study.!
BTW: I think I over dose, as I used 3 spray of 2x instant shine. (hey, I didnt read anything negative with this, so I thought my first try, I would use a bunch to see if I would be in this happy state) - will try lower dosage tmw.
OMG, yes, that is a lot of IS to spray on for self effect. I’ve overdosed myself (on a little more than what you did). Always start with one spray to test for self effects and then move up. That way you can find your sweet spot and know what your limit is. More is not always better.
When I od’d on Instant Shine it was so bad I almost quit testing pheromones. The effects for me lasted almost 24 hours after exposure, included agitation, anxiety and extreme muscle spasm to the point of intense pain.
Most people use 1 - 2 sprays of Instant Shine at normal dosage, sometimes up to 3. For you I’d recommend either swapping your 2x strength with Androtics for a regular dose, or spray it on the back of your head. That way your diffusion cloud will be a little less intense by the time it reaches your face.

I use Ishine extreme which is like 8X but I have a tolerance for it.
With 2X at one or two sprays. Just use it to the back of head or lower on the body till you get accustomed to it as Di suggested. Almost everyone gets a head rush feeling the first 2 or 3 times they use Ishine, similar to a caffeine high and even a caffeine high can make you cranky at times.

Thx Tisha,
I used it again today, with 1 spray, very comfortable and got me in a positive mood.
So, it might be just the day. dunno.
Did OP try it again and what were the affects?
AHHHH that’s explains why I’m soo sleepy…Caffeine makes me fall asleep. xD
Yes when you put it like that, it makes sense that this stuff affects people in different ways, and now I definitely see that it’s not just me. Thanks all. I’ve def had more success with about 2 sprays of IS.
