1 - No, provided you scrub-up well, you can vary your phero signature as drastically as you like. Although a regular “clean” day or two/break between a run of a particular mix and the next does help you keep perspective and improve you evaluations.
However, if you do change your sig a lot but are regularly around the same people, they can find this confusing and this can become a hurdle all by itself. Some mixes can be immediate whilst others, especially ones involving IH or A314 can take repeated exposure to hit home fully and will reveal further nuances with prolonged use.
2 - All those are good but do remember that whilst the strongest self effects can be from products like IJ and A314 but whilst they may give you confidence, they can also repel the very people you are interested-in. Whilst this can be offset with socials and A314, the none content in IJ is difficult to moderate without massive doses - and then you lose almost all its effect anyway.
3 - You certainly used to be able to “hint” at what freebie you might like to see but IME, AD have usually managed to put-in something that complemented the order in some interesting way. However, the current series of MXs prompted a change in policy a few months back - John posted a thread explaining the current position but its not leaping to hand just now.
4 - No, not easily. For starters, oils need a much higher phero concentration (7-20x depending) for an equivalent volume. You can prolong alcohol activity slightly by applying over a small amount of lotion - Use as little as you possibly can to cover the app point then give it a minute or two to sink-in, so you are not applying to sticky skin, which will impact on diffusion.
5 - You know my opinion of A1 in your context already and it is far from a beginners phero. Maybe think about working through the instants first? Also, any mix involving A1 will not count towards your RU status, which would be a shame. Lastly, IMO, people can get too hung-up on status. Which is fine if you can be congruent but in many cases they could do far better with something social/engaging that draws people to them and topples barriers/inhibitions. Anyway, just don’t use A314/IO together - IME they just wreck each other to the point of being a complete waste of product.
Female pheros - can do, it seems to work for some and others use them as alternatives to socials when moderating none. You will need to try them and see. Try searching past threads as some folk have done this before with good results. My experience was mixed - Yes I got results but not always in the range or quality I wanted.
