You are injecting too much T.
Please try this:
100mg T per week, injected twice a week, 50mg X 2
0.5mg anastrozole at time of injection
250iu hCG SC EOD [if doc will script, needed to preserve fertility and testicles]

Read that sticky and try the above and you should feel better.

There is a lot of reading and learning curve to deal with.
