Hi Lady! 
No, you’re not the only one… trust me. MX300 is the reissue of MX134. It’s TAL heavy.
MX134/MX300 are way different in feel, to me, than MX135. Though MX135 contains both TAL and TAH (56 pheromones all together!), it’s TAH heavy. It’s more a glittery, fun, attention getting mix and has a much softer feel than MX134. So, I wouldn’t use that for the situaton she describes.
MX300/MX134 is an alpha mix, the female equivalent of A314. I’m very alpha by nature and have a low tolerance for fools, so I find that I must use TAL heavy products…with caution. (Yes, that means IS/A.) One spray too much and everybody’s headin’ for the hills! Including me…only it’s a little difficult to run away from myself! 
I only pull that baby out when I need to make a very strong impression.
If you’re looking to play with the big boys and are feeling a bit over the top when using MX300…try spraying it to the back of your head or somewhat lower on your body away from your face. Then spray some Shine and/or TAH to your neck or chest where you can huff it and see if it balances it out some for you. That way they can be happy while respecting you. I find adding socials to be of help when ridin’ that bucking pony. Can’t hurt to give it a shot.
Good luck to both of you and let us know what happens.
Bella
