Just thinking about it, im a facility supervisor at a gym. I was wondering if using pheromones their would be ineffective, being that the majority of the people there are sweating… I was thinking of purchasing A314 and i considered using it at work. Is this usefull at my job?
I suppose the young fit guys will be pumping out surplus Androstenone power all around the place, No need for Raw Power here ha ha.
I have used Alpha 314 in a labouring work type enviroment and have received consistant good results with those i have been working with, especially women who seemed to be competing amoungst themselves just to please me for some reason, As i was equal to them in authority.
I was a relatively new person and had no more experience than any of the group of 14 i was working with, But every time the boss came onto the floor to demonstrate a proceedure he must have picked up on my A314 signature because he was always directing everyone to to take notice of my directions.
The days that i wore a dab of Androstenone with 2 drops Alpha 314 to work then the group of about 5 out of the 7 girls were competing amoungst themselves to help me when ever they could find any excuse to do so.
With me wearing the above application one day a very large strong butch sorta young girl came new on the job and she hated me from the very first whiff and was trying to compete with me for the full 4 hours that she was on the job, Fortunately she did not return to work after lunch break.
Where as the other girls were asking me back to sit in the car with them during breaks, where i would apply little samples of fragrance and pheromones to their wrists.
But overall Alpha 314 has proved to be a consistant product for me in social situations. And A314 for interveiws when i also spray a little Alpha Androstenol on top of my cologne. ie Spaceland.. 
It depends on congruence.
Since you work at a gym your probably in good shape which means there is already an intimidation factor. Because of this A314 will be that much more effective but not necessarily in a good way.
The couple of times I’ve worn while working out* people at the gym gave me much more space and went out of their way to ask if I was using machines/weights I clearly wasn’t. This even applied to the ultra muscular gym rats. In fact it was so effective I wore it the second time just to avoid people wanting to work in.
Don’t take this to mean that wearing A314 in a gym setting is a bad idea. A potential positive effect it had/has is that other gym members watch what you’re doing (albeit from afar) and echo your form more then usual. Something that would be invaluable if you were a trainer (or training trainers).
It could also have people looking to you for guidance, but only if go out of your way to be approachable.
*(1 drop of A314 with 1 spray of Instant Openness 2x as a buffer)
