Comp cycle

One week away from finishing my first ever cycle I ran 500mgs of test enthanate for 10 weeks. I have now
Decided to compete again this year, however the show is in 15 weeks.
Any advice would be appreciated, I want to keep things simple still but don't want to sell myself short on possibilities, do I up the dosage and get some last minute bulk? Do I add in winstrol for cutting?
This is not practical for me to do 26 weeks on my first course but the shape I have got myself into would be a waste not to compete.
