the major way you can screw up is by wearing a too sexual/aggressive mix in the wrong context when she isn’t ready for it. so a none/Edge overdose can ruin peoples’ perception of you semi-permanently almost independently of how you behave (and the self-effects are likely to get you deeper into trouble).
I haven’t had any experience of wearing a friendly mix (eg nol, Instant Openness) and screwing things up - unless I didn’t steer it right (eg talking too much or revealing things I shouldn’t due to combined effects of betanol+alcohol).
Ie it’s most likely your behaviour rather than the pheros that is to blame. So should this be a problem for you then likely you need to develop more sexual, manly subcommunication and work on eradicating any kind of needy vibe.
it’s easier to create attraction in somebody you just met than with a girl that has you in the friend zone, so why would you bother… (but you can do it - and social proof is key here)
the friendly vibe comes from not treating her like a woman. if you start projecting a sexual pheromone signature whilst acting asexual then yes it is a recipe for confusion.
