Ru58841! How long before I wash? Can I mix it with PGE2?

[Diffthinner]

I just ordered Ru58841 and a bunch of supplements, vitamins and products. I was wondereing, how long do I have to leave it on before I wash my hair? Also, I don't know if 1ml would fully cover the area I am losing hair in, since my thinning seems like it's in a diffused pattern. Can I just use a 1% concentration and apply 3 or 5 ml instead of 1?? Please help! Also, any experience with Ramatroban, D-cloprostenol, and Pge2 peptide topically? Can I mix PGE2 with the same vehicle for ru? Can I mix it with my Ru? Please help
