Low Test Running Cycle of Test E

I am new here and this is my first post, so hello everyone. There is an immense amount of great info on here. I have a few questions that some of you may be able to help me out with. I am running a cycle of Test E and I am on my fifth week. I am doing 2 a week of 250. Have seen some pretty nice results in strength gains so far but not much in weight.

My question is about gyno though. As a teenager I developed some gyno but it is just something that I have learned to live with. So far in my cycle I have not experienced any change that I can notice. I have Tamoxifen on hand but have not used any. Should I be using it and also due to my test already being low which was if I remember correctly it was around 260. Should I increase my weekly dosage? And I guess I should add that I am 28 6’3" 216 lbs and around 22% bf. Any suggestions would be great and if I did was not clear enough on anything or did not provide enough info just let me know. Thanks in advance to any suggestions or criticism.
