how fast does estrogen drop when test drops

I am on TRT in UK (Sustanon 250) due to way the medication works there is an initial spike where levels can go v high followed by a drop - during the spikes I assume my estrogen rockets up to (in line with test) - once test drops though does estrogen drop with it? I know by the end of the injection period my Test ends up around 500 and estrogen around 45.

I am carrying a a fair bit of body fat which isn't helping.

There isn't anyone who can make sense of those levels, usually E2 in the UK is in pmol/l, which 45 would be ridiculously low.

Just post the labs in their original format.

Yes, estradiol drops when test does, as test is its source.

Understanding Your Hormones

Estradiol (E2)

A form of estrogen produced from testosterone. Important for bone health, mood, and libido. Too high can cause side effects; too low can affect well-being.

DHT

Dihydrotestosterone is a potent androgen derived from testosterone. Affects hair growth, prostate health, and masculinization effects.

Free Testosterone

The biologically active form of testosterone not bound to proteins. Directly available for cellular uptake and biological effects.
