Agreed.
Even Oxandrolone and Primo, usualyy taken in a bridge for their low effect on HPTA will reduce your chances .
I made the exact same question 2 months ago, and my closet is full of Primo/ Eq/ Ox that I WON'T USE 'till my wife gets pregnant.
I'm using some Proviron this month, and if nothing happens next month I'll use Arimidex,.
