Looking to dilute RU, suggestions?

[JohnyX]

I have the premixed RU 5% in k+b carrier. I ordered this just to start me off I'll probably get the raw powder next time. I was thinking of starting on 25mg per day but this is only 0.5ml of liquid which is gonna be very hard to spread over the entire top of my head.
Could you give me any suggestions about diluting it or maybe adding it to my minoxidil to make this easier?
