From what I was able to gather:There was some thing recently with John, and Phil Viz and Trigili maybe wasn't able to parse out what the fuss was about. Anyone? Just drama?
Phil was arguing that the androgen receptor downregulates over time on cycle based on his observations with clients that the cycle becomes less effective the longer you stay on. Also that you can cycle, take a break, and return to the same dosages and continue to grow without increasing gear. He also said that the studies are not relevant to the bodybuilding population and had a limited timeframe, something like 8 weeks.
John was arguing that the evidence doesn't show that and that the limited studies show the opposite.
I think Dean St Mart and Kurt Havens are going to make a video diving into it, they're in the same camp as Jewett on their views on it.
