A little hard to follow on my cell but it looks pretty good. First off dmz is usually not recommend for a first cycle(epi and hdrol). But at 265lbs you should be ok. How old are you?
Few things that are more personal preferences but I would also add tudca on cycle for additional liver support and taurine for multiple reasons mainly back pumps.
For pct I wouldn't use milk thistle. It's been debated multiple times that it could possibly alter the effectiveness of your serm. While it's probably nothing I'm on the side of caution and I wouldn't use it. Plus your otc pct product should have some type of liver protection in it.
Lastly make sure your diet is proper for a cycle. Not eating enough is one of the biggest first cycle mistakes. Looking at your weight I'm guessing that won't be a problem lol.
I don't think week 12 is needed but it won't hurt and why skip training week 13?
