Welcome to pherotalk Ntintis!
You did your research and I do recommend that you give all the products you mentioned a shot except the tuth.
Tuth has raw none and if not used in a highly sexual environment you can come off looking like a perv.
In regards to whether or not you should go for double strength on products like Ammo or 5mcg on tuth this thread should assist you :
In terms of the social products 2X may be a good choice. The older you are the less pheromones you produce naturally so you are probably gonna use quite a few sprays with the 1x and since the dosage is stronger you will use less sprays and thus not go through the bottle so quickly and save money.
Maths here I come. lol
