Let's discuss this subject from a few points of view.

Some say this is a bad idea.
Some say they used tren alone successfully.

What is your experience and knowledge on this subject?

I prefer test with mine. Libido stays up and sides are the same for me with or without test

I would not run it without test. From my understanding, tren by itself will lower natural test. So without running test as a base you will tend to experience elevated cortisol levels while working out which lead to muscular atrophy. Not to mention a non existing sex drive and mood swings. Someone feel free to correct me if I am incorrect.
