Yeah I personally cut back on the Test a little bit when I am stacking with Tren. But I used Test Prop//Tren A just EoD injections. But I only ran Tren for 6 weeks, Test for 12. Tren is a great AAS, but it is harsh as they come, so I took it easy both times I used it.
I love the results, but Tren always makes me a bit nervous to use.
