Orals and vitamins

Will taking a multi vitamin + C keep you from having as much muscle gain as you would without while on an oral cycle?
Vitamin C acts as an anti-toxin so would it try to flush it out before all is used?
I've heard milk thristle can hurt in gains , from it cleaning your liver.

Should I take my vitamins everyday with my oral or would it put extra stress on my liver and hurt my gains is basically what im asking....

Burn me, I get into shit, I let it out like diarrhea
Got burnt once, but that was only gonorrhea
Dirty, I keep shit stinks in my drawers
So I can get fzza-funky for yah
