Whoopsie, so my info was off afterall.

Sorry guys, but i get my info from dutch boards most of the time. I never read any info there about arimidex/femara helping to get the axis back up.
I did a thorough pubmed search regarding anastrozole/letrozole and LH and now definitely have to conclude you're right.
So thanx Bryan2 for the info and the link.

What they stated on my board was the following:
When on an cycle using AAS combined with an AI, the AI would drop your axis even more during and following your PCT.
The reason was that an AI would make your receptors more sensitive + you would get a temporary upregulation of estrogen receptors (because of the aromatase enzym). This would lead to more estrogen and less testosterone. The discussion was very interesting i'd have to say between 2 biochemists.

But none of them ever brought up the fact AI's would boost LH/FSH levels DURING a cycle.

In the light of this information i had to draw my conclusions. Convinced AI's would put pressure up the axis even more for at least 6 months following a cycle (this might possibly still be true), i concluded not to make AI's my friend. But i missed the point AI's would keep LH/FSH levels normal during a cycle.
