I have been have some anxiety following a 8wk cycle of testosterone enanthate, 250 twice a week. nothing like this has happened before. I stopped pinning about 2 weeks ago, I had gotten a cold and was having congestion and it was hard to breath, I guess my question is , could high or low test Levels cause anxiety, I'm 46 years old male about 10% BF this is the 2nd time I did a 8wk test only cycle, the last time I had no problems, all I know is I'm scared and don't have anyone to talk to about this! and this is not me !!!! I'm normally mentally strong and have never felt like this in my life!! Also how long will this test stay in my body? thanks for your help Dylan!!!
