I have to say that it is only wishfull thinking when you say you can take 80-100 mg e 5 days without permenant shutdown.
I just started a HRT cycle, and as usual, my nuts began to shrink after only 3 weeks at 100mg e5d.
I think that the human body does not want to see any more test than it is producing naturally, even if your nat production is as low as 200.
My test at the time had dropped back down to 277 after being as high as 800 while on nolvadex.
You would think that my body wouldnt want to shut down at that level, but it did.
When it comes to atrophy, i dont think that dosage really maters at all. If you shut down, then it doesnt matter if it is from 100 mg weekly or 1000mg e5d. I know that lipids/chlosterol profile go down hill real fast after 500-600mg of test weekly, so why not do HRT with 300-400 weekly so long as your Blood Pressure and HDL/LDL are ok why the hell not?
