I think it usually follows that if a significant rise of testosterone is seen with normal males (82% is nothing to sniff at) then similar or better responses can be seen with hypogonadal men. In fact, I think the following statement at the end of the extract supports this:
"In five boys with delayed puberty, tamoxifen treatment appeared to activate the pituitary-gonadal axis and pubertal development."
That is before the tamoxifen treatment, their pituitary-gonadal axis wasn't working at all.
"in a normogonodal model, men producing normal levels of GnRH, tamoxifen does raise test slightly more, though this effect is transient and followed by lowered levels."
Again the effect isn't slight, and where is it written that this is followed by lower (than baseline) levels?
Also, I want to point out that the low libido that some people get while taking tamoxifen, while an issue, is probably caused by the tamoxifen itself and is not a function of your testosterone levels (which should actually be rising).
I'm not saying tamoxifen is better than clomid I'm just saying its a viable alternative. I'll believe its almost useless as Macro seems to be saying when he backs up all his statements very clearly for all to see.
