Hi,
When searching, do paxhorse or paxcalmer as the word pax only being three letters I dont' think the search allows anything under four!
Anyway, I have it also. Not sure why you want to use it, whether you want it for your horse or to mask the smell of you being nervous... But I think its just of those things that you have to try and see if it makes any difference. Like calmers or anything else - There is no mirical cure - out there, but sometimes the want for something to work can make a little difference
EG - My mare can get anxious, so if I say to myself; 'oh, I'll put on pax, that means if I get uptight, she wont be able to smell me getting uptight'' thus in the process of not being found out I am more relaxed and don't get to too ''I want everything perfect'' So it can work like that a bit... But it will not make a horse into something its not.
Goodluck.x
