and which one would be better wearing all year long, just incase the summer one was actually just meant to be worn doing the summer time lol
Two extra steering molecules - TAA and P130 in Summer. Quantities/proportions have never been revealed.
Wear it any time you like! - All the steering does is gives it a more chilled/laid-back feel and help make the mix more tasty to younger women.
Its “Blue Summer” scent is also far nicer and more widely wearable that standard Ammo’s FF21 IMO but that’s a personal thing. 
Blue summer? Is that what it’s actually called, not summer ammo
No, the Scent used for Summer Ammo is called Blue Summer (FF23).
Standard Ammo uses a different scent, FF21 whilst World Edition uses FF22 but the pheros remain the same for these two.
Oh ok now I understand lol thanks
Ive read that ammo is better for older people (for wearing it) im 26 is summer still a good choice for me because of my natural pheromones?
Depends - If the women you are most interested in are around your age, then yes Ammo might be more practical but if they are quite a bit younger, then Summer may be a better choice.
But then again, Summer is a nice chilled/laid back kind of all-rounder and I’ve enjoyed it often - although I do find it benefits from tuning with a bit of TUTH and IG to suit my age.
