here are some free test numbers from a 2001 study.....
25 mg base:593 16weeks:253
50 mg base:566 16weeks:306
125 mg base:553 16weeks:570
300 mg base:653 16weeks:1,345
600 mg base:632 16weeks:2,370
Notice that 25 and 50mg a week significantly lowered free test at the 16 week mark. The reason being is that the exo test shut down natural production. The 125mg/wk group appeared to have approx the same free test while the 300mg/wk group basically doubled their free test.
So what conclusion can be drawn by this? If you want mid range test numbers on your labs then you should probably be an approx 125mg/wk. If you want high normal range then your probably looking at a dose of around 250mg/wk.
The above study these numbers came from showed virtually no sides on the 125 and 300mg dose.
16 weeks is basically a long cycle. the principle behind HRT is that you arent supposed to come off. I was on 10 months (40+ weeks). At the 5 month mark my T levels were higher than normal. oftheshore is wanting to know if he can "goose up" his test levels but still remain in the high normal range and get a little anabolic kick or something. The thread I posted shows how it cant be done because eventually the body gets shut down and you end up worse off than before you even started any HRT.
So either you take too little and get shut down anyway (25mg-50mg), or you take too much and get shut down because its taken too long. Its no win, either take a full on cycle and go into pct and give your body a chance to normalize, or dont do it at all.
