The extra strength TUTH when where who or what
is that right for. Thanks for any insight or info.
Age mainly.
As we age, our natural Androstenone production falls and as women age, they tend to go-on higher/more overt doses of Androstenone compared to younger women. Around age thirty is often an importing tipping point in mone preferences and again in the mid/late 40s.
If you or your subjects are under 30, don’t even think on starting with the 2x product till you have found your dose with the 1x first. Then if the dose/number of sprays work-out, going to 2x can be a useful scent control/economy measure. Stronger is not always better with pheros.
Im 38 she is 32
Most of the women im around are 30 to 50.
Then 2x is a viable option here, although 2x Ammo and 1x TUTH is a wise way to get started. TUTH is in 6% Neroli - but smells a bit spicer than other instants because of its None, so its scent is less brutal than Ammo and you can easily add more sprays as you go along till you get the right dose without the scent becoming overpowering.
Another useful tactic with TUTH is to start the night wearing something like Ammo, then transition the mix by adding-in some TUTH as things get more relaxed, uninhibited and determinedly sexual. Smoother if you like. 
This is also where P83 is a valuable secondary because of its disinhibiting qualities. You will probably find that with a more overt primary mix ,you will probably benefit from a bit more P83 as well.
With this age range, you won’t usually have so much of a problem with overt products (but you can get exceptions at any age) but I’d still shy-off using TUTH at work and in sedate/polite company.
