Do estradiol levels "move" in parallel to test levels?

[krm]

Just curious - do estradiol levels "follow" test levels? With test, you have the half life of your supplement of choice, so you can almost draw a curve how your levels will look like.
Does E "follow" this curve in a timely manner?

So, as an example, let's say I'm on gel (short-acting) and I half my dose. T levels will drop almost immediately, as there's no depot.

will E level drop shortly after, or does E build up and takes a while to follow?

E does follow T but E does linger. When I had to lower my testosterone dose I felt off for a week. I believe that’s because my estradiol was still elevated but my testosterone dropped so there was a short period of imbalance. After about a week my testosterone and estradiol found and equilibrium and I started to feel good. Ive changed doses a few times whenever I go down there’s a shity period but when I go up I don’t notice that “off” feeling. Just what I’ve found, maybe it doesn’t have to do with estradiol at all.

So it seems we're talking about a few days of "lag" here?

My best guess would be approximately three days.

I have definitely noticed after any adjustments to my protocol there is a 3 day period where I feel off. Up or down. I'm sure it's a combination of all the hormones effected. Testosterone, E2, DHT ect ect. The next day I get hit with severe fatigue. To the point I feel like I'm gonna pass out and sleep the whole day. I just made an adjustment last Thursday and I have been feeling Friday, Saturday and today. Yesterday I was lucky enough I got to take a nap with my 1 year old when the fatigue set in. Hopefully tomorrow will feel better.

That greatly depends on your aromatization enzyme activity. It typically is not a linear dose dependent response.

Keep Es in check with Aromasin.
