Hi Enrique & nice to have you as a member of Pherotalk 
I see some experienced users including Lady Tisha has given their opinion about A314, Turn Up The Heat & AMMO. Ok for what i think about A314 is it give the wearer respect & high status & the trusted effect be it at work or outside.
I agreed with Lady Tisha on what she have said about TUTH, you should start with AMMO as it is a all rounder sex pheromone & it is buffered to prevent OD compared to TUTH. If you wish to know more about OD, move your cursor to the word OD & you will know what does it mean. And if you want to know more info on AMMO,TUTH or A314, check out this link> Mens Pheromone Guide revised 6/15
I hope i managed to help you there & wish you all the best if you have decided to get & test the pheros. See you
