I know a guy that started out about 187 pounds at 6 foot 1 who is on the same amount, but he was put on that dose because he has only a single nut. I believe he is now around 208, but he is looking to up the dose soon and start cycling it as other HRT people do. I know that guy trains hardcore though (HIT guy) and has been doing it for quite some time, so I know his diet and training are both pretty dead on.
It sounds like you are doing Upjohn cypionate? I would run 400-600 of that IMO, should start showing results around week 4-5 but wont be as noticeable on a lesser dose as you are running now. If you EVER were to bump up the dose the last weeks would be the last time to do it, you could have front loaded that at double dose for the first two weeks to get blood levels up.
