Hello! Good to have you!
To try and answer your questions, there’s no such thing as an unscented pheromone - they have a smell of their own, but the ones sold by Androtics (unless you pay a dose extra) all come with a light oil called Neroli. It’s a slightly citrusy scent, quite nice on its own, but subtle enough that using your own cologne on top will be absolutely fine. The mixing with the oil increases the diffusion of the mones, so I’d strongly recommend against getting the no added scent ones.
Recommandation-wise, TUTH is the “come fuck me” mone that oozes pure, raw sex. Ammo, on the other hand, is more about attraction - quite good in bars, I find, although it’s a cologne in and of itself. And quite possibly one of the best smelling colognes I know of. If you want to try something a bit off the wall, get an otg of IJ - you won’t want it regularly, so a full bottle would be a waste, but it produces some serious results to go experimenting with - layering it with some Ammo can give fun results…
Alternatively, you might want to try the killer pheromone kit - otgs of most of the Androtics range, so fun to experiment with.
Now, a couple of questions for you! Do you play sports? Like reading? Cooking? Dancing? Help us get to know you, it makes us better friends and might just help with giving you advice - all kinds of things can change how mones will work for you.
