Looking To Extend My Test Cycle

I'm on an 12wk, 500mg wk test e cycle. I'm looking to extend to 20wks. I was thinking of doing 8wks of prop/tren. This is what my source has:

trenbolone + test prop - 75mg/ml tren + 100mg/ml prop x 10ml

What do you guys think? Is this enough mg's to inject EOD? Or do you recommend something else within those last 8wks?

Thanks

I'd wait, and run a second cylce later.
