Hello and welcome to the forum,
You should consider what effects do you expect ? Some people think that they will be humped by girls while using pheromones, and they usually get disappointed. Phero effects are much more subtle, and people normally need some time to learn to recognize them. For me, it took at least 5 applications (at 5 different occasions) to be able to notice any difference.
You are 20 and your body most probably produce alot of Androstenone, which is primary ingredient in Turn Up The Heat. I wouldn’t go with more than 2 sprays, otherwise you are risking OD. You should also take into account fact that about 40 % of man can’t smell androstenone (me included), and for these who can, it has quite strong sweaty smell. The nasty fact is that you can be smelly without knowing it, that’s what happend to me once !
Phero users tend to say that they notice more effects with people who they don’t know very well. It is because your friends and people who you know well, already have well formed opinion about you, and change in your phero signature seems to have none or minor effects on them.
Other elements to consider:
-Ability of dispersion of pheros, which is low when humidity is low (during the winter the humidity is low, especially in heated space. For instance, in my apartment it is 20 % of relative humidity now, and between 50-75% during summer)
-Mood and attitude of your target. If she feels different about you, question is will she express it ?
-Phase of menstrual cycle of your target (it seems that women respond much better to androstenone during fertile days)
I think that good idea would be to continue with 1 or 2 sprays of TUTH for couple more times, wearing in club or bar and allowing yourself more time to notice the difference. You can also consider trying some other great products like Ammo, Instant Shine, Instant Openness…
If you didn’t already, you should read all sticky posts in this forum. Reading of older posts, which are great source of all information that you need, is a good idea. I believe that 99 % of all questions that come up in your head now are already answered in older threads. I hope this helps !
