Just got in my first blood test post starting TRT.
My Serum T was way up (original 127) to 682
Free T up from 6.5 to 21.8
But LH dropped from 2.7 pre TRT to 0.1
FSH dropped from 4.8 to 0.2
Estradiol up from 5.5 to 34.2
I'm on 150 test cyp/wk
500 hcg 2x a week.
But I've asked to switch...
I'm injecting 200 mg of Test Cyp per week - I've broken it up into two injections (100mg every 3.5 days). For 24-48 hours after the injection I'm really sore in my joints (hips/knees mostly). Could this be due to too much T? Could this be a reaction to the T Cyp? The pain is pretty high...

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.
