Hello Feliciano & nice to have you as a member of Pherotalk 
Hmm, i see you tried some other pheros before but have no results with them. So what kind of pheros did you use that time?
Ok i gotta agreed with my buddy Jamesbonded there, AMMO is suitable for attraction & it 's a all rounder & buffered phero. Another phero that i would like to recommend is TUTH but careful with this one as it contain a lot of Androstenone which can cause OD. To know about OD, just move your Cursor to the word OD & it will show you what does it mean
Here is a link about AMMO, TUTH & the other pheros here> mens pheromone guide
See you
