Hey brother, The classic cycle for contest prep, that most NPC and IFBB guys are always going to use, is some variation of Test/Tren/Mast. This is the "magic formula"...if there was such a thing as magic haha. There are many ways to use this cycle. Since you have about 10-12 wks left, if you wanted to run this cycle, I would make sure that you are on the test by at least 8 wks out. You can start the tren and mast at that time. Since you are short on time, I would opt for prop for your test. I would use adex for your AI, starting at 1mg EOD and if needed, go to 1mg ED. This is quite an advanced cycle, so I am assuming you have already used gear. If you wanted, you can add an oral at the end. Here is the set up. I'll draw the plan up for a 10 wk cycle, starting test sooner

Wk 1-10

Test prop 100mg EOD

adex as outlined above

3-10

tren 100mg EOD

mast 100mg EOD

7-10

Winstrol oral 50mg ED

Dont forget to do a PCT after the show. I might keep running test and adex for a few wks after the show, as you rebound. Then come off the test and start PCT. If you are interested in hiring me for your plan, hit me up over at the Next Level Nutrition page, here at Naps Gear. There is so much more to say that would take working together week by week. I hope this outline helps!
