Test stacks well with tren, test stacks well with everything.
I have gone against the grain many times and said it is ok to run tren in a first cycle if the research has been done and the doses make sense.
However, recently I ran tren for the first time in over a year. I had a bunch of stuff going on, stress at work, recent breakup of a LTR, etc. The tren kinda messed with me - I had quite a bit of anxiety, difficulty sleeping, diminished libido, even heart papitations at times.
Based on this experience I'm going to go back to recommend that people not use tren at all until they've first used test.
