Anastrozole is a powerful drug guys!

April 2017:
60 mg cyp (twice weekly) and 1/4 mg AI (twice weekly)
Total Test 863 ng/dl (264 - 916)
Free Test 23 pg/ml (6.8 - 21.5)
Estradiol, Sensitive 21 pg/ml (8.0 - 35.0)

August 2017:
50 mg cyp (twice weekly) and 0 AI
Total Test 599 ng/dl (264 - 916)
Free Test 18 pg/ml (6.8 - 21.5)
Estradiol, Sensitive 35 pg/ml (8.0 - 35.0)

I've never taken hcg.

Amazing how effective an AI is at lowering E2.
 
Vince Carter - It's a strong point when you decrease exogenous test by 20%, yet increase E2 by 75%, simply by removing your AI.
 
AbsoluteZ3RO - I think I feel best as long as there's not a lot of movement with my E2. I don't necessarily feel any significant difference between the two E2 values...eventhought the T/E ratio is quite different. As has been stated many times on these boards, multiple weekly injections can go a long way in helpng to even out a guy's E2 peaks and valleys. And I'm only injecting twice weekly. The fluctuation is what gives me problems. Not so much the end number.
 
JakeH - no, doc prefers me in that higher TT range. I think I got stuck in the trap that many guys here can relate to. Over analyzing things a bit. Been doing this for years now and always tweaking things to find that perfect fit. Big picture, my numbers usually look pretty good, I feel good, all good.

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.
