Proviron & birth control

[Ironlady]

I'm about to start a cutting cycle to harden up and got some Proviron to do that along with Clen. My question is - will this interfere with birth control pills? I know that Proviron is an estrogen blocker but not sure if it interferes with birth control pills, they have progestin and estradiol in them

Please advise........thank you

Estrogen blocker? What? Proviron is also an estrogen antagonist which prevents the aromatization of steroids. I think you are OK.
