Hello Nexz & nice to have you as a member of Pherotalk 
Hmm, a fellow singaporean, i’m from Singapore too 
Good that you decide to join this forum after reading some posts here & your keen interest in pheros there
Yes A314 is suitable for work situation like your job there but i suggest if you use it with Instant Openness, it will create better results
And yes what my buddy Mockingbird have said is correct AMMO will be more suitable than Turn Up The Heat if you want to use it for clubbing or getting attraction from girls And i would suggest using it with Instant Shine & Instant Openness for better results Btw an advice from a fellow singaporean here, if you want to get AMMO, get it in regular strength as it is more suitable for your age there & try to get the 2X strength for the instants if possible.
Here is a link about A314, AMMO, TUTH & all the Instants as well as the other pheros here> mens pheromone guide & another link on how pheros works> What pheromones can do and what they cant Updated and i leave it to you to decide on my suggestions there.
I hope i was able to help you out there. See you
