You are going to replace your testosterone with tren if you use tren alone. There are many systems in your body that rely on test. You're going to take it away from them. Then you're going to try to recover your natural test when you're done. This will be difficult to do because as your testes come back online all these systems will be needing it and you won't be making enough for several weeks. DO NOT USE TREN WITHOUT TEST. Get it?
