How to properly use and store RU58841?

I’m currently getting a 5% solution and storing it in fridge. Applying around 1-1.5ml at night. Have been doing it for 6 weeks now. I’ve also been on dut 0.5mg daily and 2.5mg minox daily for over 7 months (and fin for 2.5 years before that). I’ve never had sides from any of this stuff. It does look like I have more baby hairs on temples now than before starting RU. However, it’s hard for me to differentiate between further miniaturizing hairline and new baby hairs. For people who had successfully used and gotten results from RU58841: 1. Did you order a pre mixed bottle or mix it yourself every day? I’ve seen people mention it’s not stable for long so proper application requires frequent mixing of actual powder. 2. How long did you use it for to see results? Thank you
