You don’t need a lot of pheros to get an effect. There’s people who mix 5, 6+ products expecting an effect, which often they do, but it’s not one most desirable. (Not saying yours is this, and actually seems pretty okay with right doses) The effect you want to achieve can sometimes be gotten with just 1 or 2 products most of the time. Every product you wear together, you lessen the strength of, which with enough products becomes a ghosting state. You send too many phero messages out there and people get confused and/or irritated by the headache you give them.(Not to mention the smell at that point you could be giving off) Also when mixing, you should take care because of the ratios you are changing within the product. Effectively making the mix a whole kind of somethin new. Usually you see this type of reporting with products that are low in the amount of different phero molecules in them(like IH is only 2 molecules + maybe secret stuff). Single mixing is how you basically make your own mixes and blends. ex, androstenone + Alpha Nols
ironically on what I just said and since your new to mones, enjoy a phero baptism. Meaning go all out with your pheros the first time or few times out, but only till you notice an effect of any kind. This helps you become a believer in that pheros do work and that they can be both an improvement and hindrance to your life. After you are now believing in pheros, it’s time to sweet spot test, see what works for you, and save money in the long run by not wasting product.
putatives and singles for a new user, not exactly the best route to take when just starting out your phero journey. Familiarize yourself with a consumer line product(s) first, usually more easier to use and get effects from.
idk if this is your first time using pheros? If it is, dont do a baptism around someone(s) you really care about. It can sometimes end ugly lol. If it is, then I would start small.
To use your very very potent combo in front of someone who knows you already, may draw blanks in their head as they try to understand why they feel like they do around you. Not surprisingly, this can lead to an event where the person doesn’t want to believe this and shields themselves form this ‘new-you’. Understand that some people who know you just won’t ever change their view on you as if it were set in stone and that sometimes you just have to move on and keep interacting with new people 
All phero guru aside,
Around your girl, I would start small. 1 spray Ammo &/or 1-2 sprays IH, That’s it. Try that out for a few days around her, if you don’t notice Anything, even negative reactions, up the doses of one of the products. You can easily scare your SO, significant other, by with too much product of any kind. As I described above.
She’s young, and often young girls (<25) can be intimidated by too much -none. You shouldn’t have to worry though since Ammo (+IH) has enough buffers in it, at least for 1 spray.
Be prepared to answer to the question, “What cologne are you wearing” when wearing Ammo. You can either make something up or say the name of the cologne it’s modeled after, Creed’s Green Irish Tweed. FF21’s strong potent scent will make sure are noticed for sure. It leaves a nice whispy trail for others to follow and can easily know it’s coming from you. I myself was embarassed the first few days wearing it at work cause it was so damn strong of a scent, but I’ve learned it’s what a lot of women like and shows just how manly you are with such a scent 
Leave P83 out till your SO is more comfortable with your phero signature. If you don’t plan on getting physical or pushing the boundaries anytime soon, don’t waste money on getting it. It’s a nice product to have, but not a necessity. For public use, it can be okay, but again, it’s not something you could wear by itself and be amazed more than something like Ammo/Consumer line could provide.
Being 19 as we both are, I’ve had very nice success with Ammo as a stand alone (especially with older women and co-workers Lol). I myself have Ammo, IS, and P83 (15mcg/spray). Ammo & Is together, being the most popular combo to use, has been well for me. Around work, I don’t ever use more than 3 sprays. Ammo’s very strong scent can be overbearing for most if not given the correct amount of time to die down. I give my Ammo (@ 2 sprays) at least 15-20 mins to dry down before going to somewhere. I learned my lesson the hardway when 2 of my female co-workers said I smelled too strong and it hurt their nose. Just the day before they said they loved my same cologne. So I got cocky and put on too much too fast.
I’m going to say, out of the 8 times testing Ammo in my college’s library, I’ve had every single girl I sat next to keep stealing glances at me the moment I sit down to a few minutes later. Even had an older girl (early 20s) ask me if I knew what time it is. This is while she was o nher phone texting and in front of a computer herself. Other products havn’t really done this for me and I believe it’s because of the rad FF21 Ammo rocks and I love it. Stays on for a long time as well (3+ hours for me) could be a bad or good thing on how you look at it. Forgot to mention it’s kind of hard to scrub off the scent too Lol.
If you want you can search my journal and plop on by. It took me 3 days or so using just Ammo till I got the biggest hit of my phero use so far and I don’t think I’ll have one the same ever again at work Lol.
