He is currently touring with Flex Wheeler for a company. I thought he was sizing down by his pics. Then I seen a pic of him standing next to someone and his is still huge.
I don't think he's "officially" retired but Branch is a lot smarter than people think he is. He's very strategic with what he does so while I think he is done competing I think he'll hold most of his size to rep his supp company for now. Kinda like Kai, Kai is making money being huge and not competing that's who he is a mass monster he has no reason to really down size yet although I think Kai is most likely done competing as well
