Guy is 6’4, 325lbs. Wouldn’t be surprised if he was using/had a history of extra “supplementation”.
I think the prime concern is the guys sheer size, does it having a big frame correlate with being well endowed? According to literature, not particularly…
Actually there is rationale to this. If you diet down VERY lean (sub 6% BF) hormonal parameters go to shit. Cutting on mere TRT allows an individual to retain an extra 5-10lbs when shredded. In the grand scheme of things this makes quite a large aesthetic difference, particularly when stepping on stage.
Should also be noted lifestyle parameters no longer make quite as big a difference as they might have once made. Sleep deprivation, ethanol consumption, excess soy consumption, cannabis consumption etc can all drop testosterone quite a bit if such behaviours are frequent/intermediate in nature. On TRT one needn’t worry about these variables. The prospect of lifestyle mediated secondary hypogonadism is no longer a concern.
