Whats the best place to apply TUTH
Have a look at the App Points Sticky. Lots of good advice there:
And personally, at 31, you should be applying it somewhere prominent, near the centre where it can diffuse well. Don’t hide it away under clothing or on the periphery.
On your chest, right before sex starts.
Also what kind of self effects does it have
Self confidence, feeling more manly, a swagger… It seems to enhance moods also whatever I’m feeling.
Some people get anxiety the first times they ever use product like this. Its because your body doesnt recognize the signature is yours and is reacting to a ‘threat’ nearby. This goes away once your body starts making that signature yours…
If you get negative effects otherwise, you are using too much. It can also last a day so keep that in mind. What you apply today, some may be still there tomorrow when you apply more. If your testosterone happens to be higher to begin with and your already pumping out these pheromones in higher quantity, then be mindful of this…
self effects are well described above but do remember that they are highly variable between individuals and that you can adapt to them pretty quickly. which can land you in an unproductive cycle where you push the dose-up to maintain the self effects but at the same time, you can go into od-range, which works against you by actively discomforting or driving people away.
also, what environments are you planning on using TUTH in? ime it is more suited to uninhibited/determinedly sexual environments as opposed to sedate.formal.polite company.
and Wotan is right - if you get a woman responding well to you and pretty obviously dtf, then it is very likely that her liking for None has gone right-up compared to a cold start/introduction, so whacking-on a bit more as things get messy is quite viable. 
I’d add that TUTH also tends to cause feelings of high energy, determination, and sometimes a slight ‘disinterest’ like I’m ‘too cool’ for everyone else to me.
I think TUTH is best applied chest or neck region.
