This is a good idea in my opinion
Test @400 and tren e @ 700 1-12.
Test will just be used to maintain a stable libido, less estrogen sides from test. Since these two fight for the same receptor it would be wise to just keep the tren high and test low(just for maintenance. Thats what has worked best for me in the past.
Ive ran
test @1000 1-16
Tren @500. 1-16
With more sides, bloat, gain fat, my waist went from a 32-34, i gained 30 but most of it was fat/water and i did not look lean after this cycle.
Then i was suggest to flip it around
Test @400
Tren @800
Minimal sides, i looked leaner, better and felt better, i was stronger, more vascular, i dropped fat, my waist size went from a 33 to a 30, gained 25 pounds of lean muscle in 14 weeks.
So its your choice
I would recommend you to keep the tren higher than the test and just use test for maintenance
