Crash with minoxidil

[Gonzo]

I've been using minoxidil for 15 years without issues. I tried a different brand and crashed. The new brand has the same % of minoxidil and the same fillers (unknown % of fillers)
I asked gpt chat, who says it may be different percentage of fillers, which allows a major sistemic absorption in the new brand.
So am I fucked up now? Now I also have PFS on top of pssd? This is the worse possible escenario.
It seems tha minoxidil works with androgen receptors and it's also a 5ar inhibitor. I didn't believe this as I used it for 15 years without side effect, but it seems the new brand catched my androgen receptors.
I'm terrified
