[49ER]

Hey what's up guys I've been reading a lot what I can off ology for over a year and finally joined. I'm 33 6ft tall about 245lb I'm I've packed on a lot of muscle but just can't figure out my diet to lose fat around stomach. I just signed up with 3js so I can't wait for my new diet plan. I know I did wrong but I started my first cycle over a year ago went 500mg test e ew 12 weeks and tren ace 100mg eod week 7-12 second cycle same except I ran test and tren e 12 weeks I had everything I could possibly need letro tamoxifen Clomid armidex. I got really nice results I love tren but I lose so muchsleep so my next cycle I'm running test e 600 and eq 500 and mast e for 15 weeks my question is can I throw in 100 or 200mg of deca just for joint issues? Any advice will be appreciated
