Finished a raw hypnotic techno track (-10 dB peak). How should I prep it for DJ sets, sharing, and labels?

Hi everyone, I have a few questions and I'd really like to hear your thoughts.

l've propluced a techno track in a PoleGroup/WarmUp style, so it's quite raw and hypnotic. I made it using only Ableton's stock plugins and my own samples, since I don't currently have my MacBook and I'm working on my girlfriend's PC. During the production process, I also worked on the mix, refining it further after completing the arrangement. At the moment, the master peaks at around

-10.1 dB.

At this point, I'm wondering what the ideal next steps would be. How should I prepare the track (pre-master, master, headroom, mono compatibility, phase, etc.) if I want to test it in one of my DJ sets, send it to a DJ friend so they can play it, or possibly submit it to a label?
