I’m about to order a full sized bottle of ammo, and I just want to know what are people’s thoughts on the other versions compared to the original?
The “summer” version also comes with some kind of “booster”, anyone know much about that?
The best scent is the one you like best.
For me that is FF22 - World Edition, a more euro-centric floral-based scent. FF21 - Standard is a strong, young clean/detergenty smell that doesn’t suit me, and I get mild irritation from it. I can’t deny that it is a very good diffuser though.
FF23 - Blue Summer is the best of the lot IMO - but yes, Summer is a different product as it has TAA and P130 in the mix, which gives it a more chilled and better moderated feel.
My first post in a while lol - I found world edition to smell a bit feminine - nice smell but floral scents aren’t for me. Regular ammo (ff21) I find to be a bit too strong, and smells like laundry detergent. I just got summer ammo and love it. The mones in it are different then regular ammo. To me, it smells like a powdery aquatic. The scent isn’t too strong either, so if you’re layering with other scents you won’t be the cologne guy.
I’m glad I asked this, I’m really picky about smells, especially if I’m going to be wearing it, but I don’t want to spend $45 to test them all out. Summer really sounds like my best bet. Plus, I get uncomfortable when people get too near me, even girls I like, maybe that TAA can calm me down a bit =P .
The thing with FF22 is also that it combines very well indeed with a number of good colognes - that give it a more masculine character but still retain a distinctive/original/mature scent. There is no way you can do that with FF21!
FF23 however is a brilliant scent, although it is difficult to combine with anything stronger than Neroli. But if you are going with Summer, you may need to bolster it with something else to offset its more gentle/youthful nature. P75 or TUTH for sexuals and a bit of IG make it much more suitable for an older guy. 
I agree with mobocaster. I’m only 20 and as such have a higher none production. I can’t get away with more than one spray of ammo, summer is tamed down and I typically wear 2 sprays with good results so far.
I think world edition F22 is the best of the lot… F21, as mobo pointed out, smells like detergent and Summer F23 smells like cheap over the counter deodrant (at least to me)
Summer Ammo smells really nice to me, but when it comes to AMMO, I’m an F21 fan! People say it smells like detergent, but to me, it has a sweet smell.
The other scents, to me, smells boring.
Standard Ammo has an excellent scent IMO can be over powering if you use a few sprays though. It is excellent as a cover scent if using other mones in addition eg. Shine. Ammo’s scent is very long lasting,I can still detect ammo scent the next day.
Very useful to cover the additional “NONE” that I add to augment for an older user.
Summer Ammo has a more subtle scent which I also like alot, Works well with the TAA and P130. Overall a more universally acceptable scent IMO
I am torn between the two TBH.
A combination of both Ammo original and Ammo Summer works very well for me.
