Need some advice on therapies, cycle advice and mixing compounds.

I have been eating very clean for a little more than a year now generally eat about 6 meals daily as well as hitting the gym on a regular basis. During this time I've managed to maintain weight, shed body fat but I have not put on any considerable amount of muscle. At least nothing that would show my efforts over the last year. I talked with my doc about my concerns and he suggested we do a hormone workup. My T levels came back at 36. We recently started replacement therapy with a new FDA approved long acting test called Aveed. I inject bi-weekly and so far have noticed some considerable changes.

My question is:
I am considering adding a pro hormone and possibly an antiestrogen to my regimen but am unsure if this is advisable. I will be on the injections for the foreseeable future.

If so, what would be best to use and/or cycle while having the injections?

Or, should I just stay the course with my test therapy and give it some time to do its thing?

Again, my diet is clean. Maybe too clean. Also, am I setting up to hit a brick wall with test therapy and should I be taking anything else along with it like antiestrogens or something.

Advice appreciated.
