Let me share something with you:
if you have a Low budget: RU + E3 topical. Continue finasteride and OM if you are using those. Big 3 is not an option. Microneedlling with minoxidil
A Medium budget: RU higher dosage + Latan + E3 higher dosage topical for regrowth. Duta and OM oral. Add SMI oral if it fits your budget. UT is more affordable than ARV at the correct dose. So I believe it fits in here as a SARD. If you use minoxidil, add tretinoin to accelerate its effect. Buy a D2 with 12 needle heads, it's worse it.
Higher budget: Keep using what you have. Try to experiment with more "exotic" topicals that have high potential (UT, WAY).: Go for expensive stuff at the right dosage. Don't try to cut corners. keep using some proven stuff that don't clash with what you are experimenting with. Have a no regret mindset on what you are trying to achieve.
For all the above, use the right vehicle. Avoid too much DMSO and PG. DMI and Transcutol are much better for the skin. Get a .001g scale or a .0001g one if you can afford it for your topicals and making pills yourself.
