I've also recently moved to a upper/lower split focusing on hypertrophy. I was doing 4 days PPL in a lower rep range before.
I'm liking it, seeing more growth and I'm losing weight pretty quickly right now (also losing muscle mass according to the fancy scale at the gym but I can get that back later) coupled with the keto-style diet I've gone on. Speaking of the fancy scale, when I first started at the gym it recorded my visceral fat at a level of 26. This week I hit 12 which is the very end of the "healthy" scale.
The two days of lower are a bit of a killer but I did add deadlifts on my second lower day, something which I didn't think I'd ever do as I was scared that I'd throw my back out. Haven't had any problems and I think it might actually be my favourite lift right now, there's something really satisfying about it even if it ruins me because of how taxing it is on the whole body.
