Bloodwork (estradiol LC/MS)

ad

Wanted to general advice for how long most wait to get their blood work during cycle. Blood work looked good to go before starting so I have baseline reference.

Running 375mg Test E/week (anavar 30-40mg on the back end) and wanted to dial in on how much arimidex I may need, if any at all.

Basically was planning on getting total t with free (LC/MS) and estradiol (LC/MS), see where I’m at and if estradiol levels are rising to a point near/outside of reference range. If yes, I’ll throw in arimidex .5mg around each injection (Mon/Th) then get estradiol (LC/MS) 1-2 weeks later to see if I hit that sweet spot or not and adjust accordingly.

Would 2-3 weeks into cycle (4-6 injections) typically be a good start for when to assess these values?

Wait 2 wks after starting AI to get bloods. With long ester AI is started 4th wk so I would test 6 wks in and adjust AI as needed then.

That’s what I want to avoid. IMO it makes sense to hold off on the AI until week 4 bloods as you suggested then go from there rather than prophylactically starting adex, like some do. Would you agree with this?

Looked into adex but specific questions like this seem hard to retrieve. I also see some who argue for ED or EOD use while other claim 6-12 hours post injection is sufficient. With a half life of 30-60 hours it seems pretty variably and im not sure if steady state serum concentrations are as much a priority compared to test.
