I'm running tren right now and just finished a 3 week kickstart with superdrol.... and i have to say the sides were pretty harsh. I am glad i'm done with the superdrol. my blood pressure was insanely high and i would get periodic attacks of anxiety regarding blood pressure. Also, I am running test cypionate at 200 mg a week, so some of the symptoms like lethargy and low libido were not an issue for me, I couldn't imagine how rough it would be without running some form of test...
So in answer to your question, i would not run the sd and tren concurrently.. the sides outweigh the potential gains and in fact, i believe that the severity with which my lipids were trashed may actually have inhibited some of my gains from the superdrol. I will never run these two compounds again and would strongly advise anyone considering it to try a different stack
