I noticed that the pheros smell different if you spray them versus dripping. Sprayed smells much sweeter.
I’m sure spray diffuses more, but I would think dripping has longer retention?
Any thoughts?
I usually spray since dripping takes too much time, you need to unscreew the bottle cap first and blah blah blah 
I Like Spraying too it helps difuse it better and you can smell it right a way always good to know that what you spray on yourself can be smelt right away on your own nose, Like MB said drip takes too much time especially if your in a club you have to go all the way into the toilet and find an empty cubilcle and re-apply too much hard work.

To spray, drip or dab, that is the question. Dabbing is the most precise as you can apply to tiny areas, e.g., behind ears or nap of the neck. Works with both oil and alcohol carriers. Dripping is best used with oil carriers or else you get a mess and quick. Spraying is imprecise and wastes much precious fluids by spewing the over-spray into the atmosphere. However it affords the best coverage and is the fastest and most convenient app method while on the go. I mainly dab 'n drip at home and spray on the run in cars, parking lots and bathrooms. It’s all good.
I really like to spray, I think it’s fast and effective and really does the job.
I prefer to drip CTTM on my head, it seems to last a lot longer. Ammo I just spray. I don’t have any other sprays that I use as consistently as Ammo. Spaceland I’ve tried dripping and it’s just as effective as spraying.
Also: spraying is good for those times you want “general purpose” wide area effects (like your “social” pheromones). Dabbing or other small area applications are good for when you want to “direct” attention somewhere specific (perhaps more for your “sexual” pheromones).
Some forum users have reported good results by applying high androstenone products to small specific areas such as upper lip (kissing) or around crotch (hmm.. could see some “kissing” there too… besides other things).
I put androstenone on my zipper.
seriously? how does that work out for you? How much?
