Honestly, I'd be surprised if he didn't love it. From what I've heard, he was very strong. Someone who trained with him once said they witnessed him incline bench press 600 lbs (272.5 kg)!
I've read that Chad at least used to be a fan of Anadrol for his athletes. And why not, it's hard to beat a stack of Test, Tren and Anadrol. Or even Anadrol by itself, which I did for extended periods in my youth. Nasser was a fan, Milos said Nasser used up to 10 a day and showed it in his old journal notes. In a podcast Chad said Nasser's eyes were turning yellow, because he was using 5 a day with a ton of Winstrol. Dianabol does make me feel better mood-wise though and those who say it's shit and antiquated are full of shit IMO.
