test p/tren a cycle help

[pballer]

Hey dudes. This will be my fourth cycle and I would like to test the tren waters but need a little clarification. Test p and tren a both have a 48 hour life correct? So should I be pinning 75mg tren a and 100mg test p EOD? Should I just stick to the norm 8 week cycle? Any advice would be great. Have been researching for hours and majority of them are the "this is my very fist cycle" posts that all go down hill and provide no info.

Thank you for your time!
