I’m the same with Mx300 BUT…don’t give up on it though! I have found that the bitchiness is dosedependent, so I’m fine with 2 sprays or so. I also found that if I layer it with a softer social (IH etc, or a few spritzes of Mx274) you get the great effects of Mx300 without the bitch-claws coming out 
There is a big difference in my (male) colleagues behaviour towards me depending on if I send out the “I’m a stong, assertive & competent woman” and “I’m a PMS’ing, aggressive bitch/feminist” vibe…
