All depends on how your body reacts to the hormones I guess. My buddy was on test (don't remember how much, but over 1g for sure), 1g tren (I know, fucking crazy powerlifters), and some orals. Got his gf pregnant and she just gave birth a couple months ago to a healthy baby girl. I suspect he's an anomaly though.
And before people start saying its not his, the kid looks like a spitting image of him.
