Taking the Eq as the limiting factor, you just needtoplump for a duration.
600mg EW would use 3ml EW and give 13 weeks minus some for losses, call it 12 weeks. I remember that you posted somewhere that 12 weeks is your limit for a cycle so go with 12 weeks. Calculate your spare and spread it over the first couple of weeks as a frontload.
I've no idea what levels of Test you like to run but let's plump for 750-1000 EW. We can shoot higher on the sust at the beginning due to the long esters so let's take 3ml of Sust to start the cycle shot EOD or just M, W, F.
Run the Sust at 3ml EW until it runs out which will be during the sixth week. At that stage, switch to Cyp, also at 3ml EW. You'll be cruising on the long esters of the Sust so can probably still get away with 3ml EW, even though it's less at 750 than the 900 of the Sust, which will see you through to about the time that the Eq runs out. Switch to Prop for a further two or three weeks.
You've gone over the 12 weeks while running the prop but you need to wait for esters to clear anyway.
Job done. Have a nice cycle.
