Good advice above - so i won’t repeat it.
I will say that you need to be careful with none and it is best to start low and build-up slowly till you find your effective dose, so diving int the sort of fairly overt mixes you suggest is maybe not the best way. Have a look at this thread and particularly the “Sweet Spot” post:
TUTH in social environments is a fickle one at best - clubs and more overtly sexual situations are often the places you will get the best out of it. Moderating it with something like IS or better still IO will help a lot.
Smell - Well, yes that can happen ant does depend a lot on the bacterial comtent of your skin and sweating, heat humidity etc. Pheros diffuse/break down fastest in warm humid places. You should still have a good four hours or so before needing a freshen-up, with more like six hours in a cooler place. Also remember that scent response varies widely with pheros and whilst you might smell nothing, others might detect a strong scent at tiny doses no matter what cover you use, whilst others will smell nothing at all - So don’t be put-off by the odd negative reaction, the vast majority won’t be troubled.
Cologne - yes, you can spray over alcohol-base pheros or use different points but do leave a couple of minutes to let the solvent evaporate first. You only need to keep your application points strictly apart when using oil-base, spraying over can wreck diffusion.
Another thing to remember is that there is a known issue with Asians and none sensitivity - Asian women can be responsive to far lower levels of none compared to other races and a dose that would be fine around western women might well be into OD for them - Again, a little time finding your sweet spot is well worth the effort.
You should also look at IG as well as it also appears that Asian women can be very responsive to Androsterone and maybe you should consider using that in conjunction with the IS and a reduced dose of Ammo. IG’s light smart/smooth/charming, status effects will do you no harm anyway.
