@Cataceous, this is really useful. I am currently tying to find actual data on E2 levels over the course of hours after a testosterone injection. I think your estimates here are good. Since posting this, have you seen any data on this?
@Nelson Vergel, your book is priceless. I scanned over the estradiol section and see a ton of good information, but don't see anything that answers how quickly testosterone aromatizes in terms of hours after injection.
I have been doing a low dose daily injection, and lately, around 10-12 hours after injecting, I start getting really anxious and jittery. My first instinct is to assume I am supraphysiologic, but my doses are modest compared to what many are doing. Labs from last week show Total T (LCMSMS) is 651 and Free 122.5 pg/ml (46-224). Estrogen is 45 pg/ml. So, I don't think the bad-feeling anxiety is from T, although this was technically a trough (first thing in the morning, prior to injection), so peaks are higher. My lead suspects are E2 or DHT. I suspect E2. Unfortunately, I did not get an ultrasensitive test. But, this is driving me nuts, so I may break down and take a small dose of anastrazole to see if that makes a difference.
Does 10-12 hours seem like a reasonable estimate for peak E2 levels? Or, it may be dropping levels that I am feeling - a common migraine trigger in women.
