I suppose it depends on how each compound effects you personally at each dosage... My first time with tren I did 75mg-100mg (ramped up after second week) EOD tren with 125mg test per week, I felt great most of the way through and looked really freaky by the end of my run....
This time around I've gone for 100mg test EOD 100mg tren EOD, on this run I'm a hell of a lot stronger, PRs being blown straight out of the water, but then I'm eating more... The only other difference is I don't look nearly as good this time due to test bloat despite a 100% clean diet, I'm coming to the conclusion that 250mg per week of test is a max for me....
