Stacking fina, cytomel, winny, clen for a show that is a year away

I am trying to get ready for my first show for next June. I have one year to get ready and the guy that is training me has gotten me fina, clen, cytomel, and winny amps. I am currently 275 pds., 24yrs old, 6'3" and bodyfat somewhere in the middle to low teens. I am currently off everything and am suppose to start this stuff in 2 weeks. I have two questions: 1) have you guys ever heard of people cutting down this far out and then trying to bulk back up 2) I know this stack is going to cause night sweats and on top of hardly any carbs is probably going to put me in a foul mood, other than that will I have any other bad side effects. I believe I have my diet down pat. If you guys can help me in anyway please do. Thank you
