Mixing minoxidil powder

[combatant]

Hello.

Recently I acquired minoxidil powder for sake of mixing minoxidil 5% solution. I did it since in my country is really hard to get minoxidil and even if you do it is really expensive.

Since I need like 5 ml/day buying expensive minoxidil is not a solution.

So I tried to mix my own. I made 5% solution using 2500 mg of minoxidil powder and 50 ml solution of 96% ethanol (63%), propylene glycol (20%) and distilled water (17%). So my calculations were correct to make 5% minoxidil.

However the solution didn't mixed as well as expected. Powder didn't solved completely, there are leftovers on the bottom of bottle. And if I shake the bottle, minoxidil powder floating in liquid becomes obvious.

Will this solution even work? Did anyone tried to mix minoxidil powder? How to make it better?

Thanks
