[QUOTE="Fireproof, post: 47803, member: 13038"] This is an interesting thing to try to predict. Just thinking out loud... if you assume that the testosterone serum levels peak and wane similar to the graph below, then test level will peak about 24 hours after injection. I don't know the time delay of aromatization, but let's assume it aromatizes quickly...then e2 levels should be at a peak 24 hours after your Test Cyp injection and before you take your arimidex. For the e2 trough - I've been told that half life of Anastrozole is 12 hours. (I expect arimidex to be similar...but maybe not). Anyway - assuming a similar curve, peak level of your AI in your system is probably a few hours after taking it... So it would seem that your e2 trough would likely be on your non-injection day, when your AI is peaking in your system, which would be a 3-4 hours after taking it. Just trying to guess. HOWEVER - the 2nd graph below indicates that with daily Anastrozole dosing, plasma levels tend to even out after a few days showing minimum peaks and valleys - so I'm not sure your AI dose timing really matters that much. Test Cyp Levels after Single Injection....
