Sorry to disagree, but I've seen a HD video of him measuring quite honestly about 8.5" (21.6 cm) NBP x 7.5" (19 cm), and he wasn't even 100% hard, with no tricks, pumping etc, all natural. So, based on that, I think we can safely guess that at his biggest/hardest, like during a peak of effect of an erection enhancement drug, he can reach about 9" (23 cm) BP with a solid 7.5"+ (19 cm+) rock hard girth. And, speaking from my own experience (I've gained in some occasions a temporary girth boost of 1"+ through pumping before sex), with the proper technique, he can get even more girthier, about ~8.5"+, after a long and highly intense pumping session, if he decides to try.
